JSON Editor =========== ![JSON Schema -> HTML Editor -> JSON](https://raw.github.com/jdorn/json-editor/master/jsoneditor.png) JSON Editor takes a JSON Schema and uses it to generate an HTML form. It has full support for JSON Schema version 3 and 4 and can integrate with several popular CSS frameworks (bootstrap, foundation, and jQueryUI). Check out an interactive demo (demo.html): http://jeremydorn.com/json-editor/ Download the [production version][min] (22K when gzipped) or the [development version][max]. [min]: https://raw.github.com/jdorn/json-editor/master/dist/jsoneditor.min.js [max]: https://raw.github.com/jdorn/json-editor/master/dist/jsoneditor.js Requirements ----------------- JSON Editor has no dependencies. It only needs a modern browser (tested in Chrome and Firefox). ### Optional Requirements The following are not required, but can improve the style and usability of JSON Editor when present. * A compatible JS template engine (Mustache, Underscore, Hogan, Handlebars, Swig, Markup, or EJS) * A compatible CSS framework for styling (bootstrap 2/3, foundation 3/4/5, or jqueryui) * A compatible icon library (bootstrap 2/3 glyphicons, foundation icons 2/3, jqueryui, or font awesome 3/4) * [SCEditor](http://www.sceditor.com/) for WYSIWYG editing of HTML or BBCode content * [EpicEditor](http://epiceditor.com/) for editing of Markdown content * [Ace Editor](http://ace.c9.io/) for editing code * [Select2](http://ivaynberg.github.io/select2/) for nicer Select boxes * [Selectize](http://brianreavis.github.io/selectize.js/) for nicer Select & Array boxes * [math.js](http://mathjs.org/) for more accurate floating point math (multipleOf, divisibleBy, etc.) Usage -------------- If you learn best by example, check these out: * Basic Usage Example - http://rawgithub.com/jdorn/json-editor/master/examples/basic.html * Advanced Usage Example - http://rawgithub.com/jdorn/json-editor/master/examples/advanced.html * CSS Integration Example - http://rawgithub.com/jdorn/json-editor/master/examples/css_integration.html The rest of this README contains detailed documentation about every aspect of JSON Editor. For more under-the-hood documentation, check the wiki. ### Initialize ```js var element = document.getElementById('editor_holder'); var editor = new JSONEditor(element, options); ``` #### Options Options can be set globally or on a per-instance basis during instantiation. ```js // Set an option globally JSONEditor.defaults.options.theme = 'bootstrap2'; // Set an option during instantiation var editor = new JSONEditor(element, { //... theme: 'bootstrap2' }); ``` Here are all the available options:

Option	Description	Default Value
ajax	If `true`, JSON Editor will load external URLs in `$ref` via ajax.	`false`
disable_array_add	If `true`, remove all "add row" buttons from arrays.	`false`
disable_array_delete	If `true`, remove all "delete row" buttons from arrays.	`false`
disable_array_reorder	If `true`, remove all "move up" and "move down" buttons from arrays.	`false`
disable_collapse	If `true`, remove all collapse buttons from objects and arrays.	`false`
disable_edit_json	If `true`, remove all Edit JSON buttons from objects.	`false`
disable_properties	If `true`, remove all Edit Properties buttons from objects.	`false`
form_name_root	The first part of the `name` attribute of form inputs in the editor. An full example name is `root[person][name]` where "root" is the form_name_root.	root
iconlib	The icon library to use for the editor. See the CSS Integration section below for more info.	`null`
no_additional_properties	If `true`, objects can only contain properties defined with the `properties` keyword.	`false`
refs	An object containing schema definitions for URLs. Allows you to pre-define external schemas.	`{}`
required_by_default	If `true`, all schemas that don't explicitly set the `required` property will be required.	`false`
keep_oneof_values	If `true`, makes oneOf copy properties over when switching.	`true`
schema	A valid JSON Schema to use for the editor. Version 3 and Version 4 of the draft specification are supported.	`{}`
show_errors	When to show validation errors in the UI. Valid values are `interaction`, `change`, `always`, and `never`.	`"interaction"`
startval	Seed the editor with an initial value. This should be valid against the editor's schema.	`null`
template	The JS template engine to use. See the Templates and Variables section below for more info.	`default`
theme	The CSS theme to use. See the CSS Integration section below for more info.	`html`
display_required_only	If `true`, only required properties will be included by default.	`false`

__*Note__ If the `ajax` property is `true` and JSON Editor needs to fetch an external url, the api methods won't be available immediately. Listen for the `ready` event before calling them. ```js editor.on('ready',function() { // Now the api methods will be available editor.validate(); }); ``` ### Get/Set Value ```js editor.setValue({name: "John Smith"}); var value = editor.getValue(); console.log(value.name) // Will log "John Smith" ``` Instead of getting/setting the value of the entire editor, you can also work on individual parts of the schema: ```js // Get a reference to a node within the editor var name = editor.getEditor('root.name'); // `getEditor` will return null if the path is invalid if(name) { name.setValue("John Smith"); console.log(name.getValue()); } ``` ### Validate When feasible, JSON Editor won't let users enter invalid data. This is done by using input masks and intelligently enabling/disabling controls. However, in some cases it is still possible to enter data that doesn't validate against the schema. You can use the `validate` method to check if the data is valid or not. ```javascript // Validate the editor's current value against the schema var errors = editor.validate(); if(errors.length) { // errors is an array of objects, each with a `path`, `property`, and `message` parameter // `property` is the schema keyword that triggered the validation error (e.g. "minLength") // `path` is a dot separated path into the JSON object (e.g. "root.path.to.field") console.log(errors); } else { // It's valid! } ``` By default, this will do the validation with the editor's current value. If you want to use a different value, you can pass it in as a parameter. ```javascript // Validate an arbitrary value against the editor's schema var errors = editor.validate({ value: { to: "test" } }); ``` ### Listen for Changes The `change` event is fired whenever the editor's value changes. ```javascript editor.on('change',function() { // Do something }); editor.off('change',function_reference); ``` You can also watch a specific field for changes: ```javascript editor.watch('path.to.field',function() { // Do something }); editor.unwatch('path.to.field',function_reference); ``` ### Enable and Disable the Editor This lets you disable editing for the entire form or part of the form. ```js // Disable entire form editor.disable(); // Disable part of the form editor.getEditor('root.location').disable(); // Enable entire form editor.enable(); // Enable part of the form editor.getEditor('root.location').enable(); // Check if form is currently enabled if(editor.isEnabled()) alert("It's editable!"); ``` ### Destroy This removes the editor HTML from the DOM and frees up resources. ```javascript editor.destroy(); ``` CSS Integration ---------------- JSON Editor can integrate with several popular CSS frameworks out of the box. The currently supported themes are: * barebones * html (the default) * bootstrap2 * bootstrap3 * foundation3 * foundation4 * foundation5 * foundation6 * jqueryui The default theme is `html`, which does not rely on an external framework. This default can be changed by setting the `JSONEditor.defaults.options.theme` variable. If you want to specify your own styles with CSS, you can use `barebones`, which includes almost no classes or inline styles. ```javascript JSONEditor.defaults.options.theme = 'foundation5'; ``` You can override this default on a per-instance basis by passing a `theme` parameter in when initializing: ```js var editor = new JSONEditor(element,{ schema: schema, theme: 'jqueryui' }); ``` ### Icon Libraries JSON Editor also supports several popular icon libraries. The icon library must be set independently of the theme, even though there is some overlap. The supported icon libs are: * bootstrap2 (glyphicons) * bootstrap3 (glyphicons) * foundation2 * foundation3 * jqueryui * fontawesome3 * fontawesome4 By default, no icons are used. Just like the CSS theme, you can set the icon lib globally or when initializing: ```js // Set the global default JSONEditor.defaults.options.iconlib = "bootstrap2"; // Set the icon lib during initialization var editor = new JSONEditor(element,{ schema: schema, iconlib: "fontawesome4" }); ``` It's possible to create your own custom themes and/or icon libs as well. Look at any of the existing classes for examples. JSON Schema Support ----------------- JSON Editor fully supports version 3 and 4 of the JSON Schema [core][core] and [validation][validation] specifications. Some of The [hyper-schema][hyper] specification is supported as well. [core]: http://json-schema.org/latest/json-schema-core.html [validation]: http://json-schema.org/latest/json-schema-validation.html [hyper]: http://json-schema.org/latest/json-schema-hypermedia.html ### $ref and definitions JSON Editor supports schema references to external URLs and local definitions. Here's an example showing both: ```json { "type": "object", "properties": { "name": { "title": "Full Name", "$ref": "#/definitions/name" }, "location": { "$ref": "http://mydomain.com/geo.json" } }, "definitions": { "name": { "type": "string", "minLength": 5 } } } ``` Local references must point to the `definitions` object of the root node of the schema. So, `#/customkey/name` will throw an exception. If loading an external url via Ajax, the url must either be on the same domain or return the correct HTTP cross domain headers. If your URLs don't meet this requirement, you can pass in the references to JSON Editor during initialization (see Usage section above). Self-referential $refs are supported. Check out `examples/recursive.html` for usage examples. ### hyper-schema links The `links` keyword from the hyper-schema specification can be used to add links to related documents. JSON Editor will use the `mediaType` property of the links to determine how best to display them. Image, audio, and video links will display the media inline as well as providing a text link. Here are a couple examples: Simple text link ```js+jinja { "title": "Blog Post Id", "type": "integer", "links": [ { "rel": "comments", "href": "/posts/{{self}}/comments/", // Optional - set CSS classes for the link "class": "comment-link open-in-modal primary-text" } ] } ``` Make link download when clicked ```js+jinja { "title": "Document filename", "type": "string", "links": [ { "rel": "Download File", "href": "/documents/{{self}}", // Can also set `download` to a string as per the HTML5 spec "download": true } ] } ``` Show a video preview (using HTML5 video) ```js+jinja { "title": "Video filename", "type": "string", "links": [ { "href": "/videos/{{self}}.mp4", "mediaType": "video/mp4" } ] } ``` The `href` property is a template that gets re-evaluated every time the value changes. The variable `self` is always available. Look at the __Dependencies__ section below for how to include other fields or use a custom template engine. ### Property Ordering There is no way to specify property ordering in JSON Schema (although this may change in v5 of the spec). JSON Editor introduces a new keyword `propertyOrder` for this purpose. The default property order if unspecified is 1000. Properties with the same order will use normal JSON key ordering. ```json { "type": "object", "properties": { "prop1": { "type": "string" }, "prop2": { "type": "string", "propertyOrder": 10 }, "prop3": { "type": "string", "propertyOrder": 1001 }, "prop4": { "type": "string", "propertyOrder": 1 } } } ``` In the above example schema, `prop1` does not have an order specified, so it will default to 1000. So, the final order of properties in the form (and in returned JSON data) will be: 1. prop4 (order 1) 2. prop2 (order 10) 3. prop1 (order 1000) 4. prop3 (order 1001) ### Default Properties The default behavior of JSON Editor is to include all object properties defined with the `properties` keyword. To override this behaviour, you can use the keyword `defaultProperties` to set which ones are included: ```json { "type": "object", "properties": { "name": {"type": "string"}, "age": {"type": "integer"} }, "defaultProperties": ["name"] } ``` Now, only the `name` property above will be included by default. You can use the "Object Properties" button to add the "age" property back in. ### format JSON Editor supports many different formats for schemas of type `string`. They will work with schemas of type `integer` and `number` as well, but some formats may produce weird results. If the `enum` property is specified, `format` will be ignored. JSON Editor uses HTML5 input types, so some of these may render as basic text input in older browsers: * color * date * datetime * datetime-local * email * month * number * range * tel * text * textarea * time * url * week Here is an example that will show a color picker in browsers that support it: ```json { "type": "object", "properties": { "color": { "type": "string", "format": "color" } } } ``` #### Specialized String Editors In addition to the standard HTML input formats, JSON Editor can also integrate with several 3rd party specialized editors. These libraries are not included in JSON Editor and you must load them on the page yourself. __SCEditor__ provides WYSIWYG editing of HTML and BBCode. To use it, set the format to `html` or `bbcode` and set the `wysiwyg` option to `true`: ```json { "type": "string", "format": "html", "options": { "wysiwyg": true } } ``` You can configure SCEditor by setting configuration options in `JSONEditor.plugins.sceditor`. Here's an example: ```js JSONEditor.plugins.sceditor.emoticonsEnabled = false; ``` __EpicEditor__ is a simple Markdown editor with live preview. To use it, set the format to `markdown`: ```json { "type": "string", "format": "markdown" } ``` You can configure EpicEditor by setting configuration options in `JSONEditor.plugins.epiceditor`. Here's an example: ```js JSONEditor.plugins.epiceditor.basePath = 'epiceditor'; ``` __Ace Editor__ is a syntax highlighting source code editor. You can use it by setting the format to any of the following: * actionscript * batchfile * c * c++ * cpp (alias for c++) * coffee * csharp * css * dart * django * ejs * erlang * golang * groovy * handlebars * haskell * haxe * html * ini * jade * java * javascript * json * less * lisp * lua * makefile * markdown * matlab * mysql * objectivec * pascal * perl * pgsql * php * python * r * ruby * sass * scala * scss * smarty * sql * stylus * svg * twig * vbscript * xml * yaml ```json { "type": "string", "format": "yaml" } ``` You can use the hyper-schema keyword `media` instead of `format` too if you prefer for formats with a mime type: ```json { "type": "string", "media": { "type": "text/html" } } ``` You can override the default Ace theme by setting the `JSONEditor.plugins.ace.theme` variable. ```js JSONEditor.plugins.ace.theme = 'twilight'; ``` #### Booleans The default boolean editor is a select box with options "true" and "false". To use a checkbox instead, set the format to `checkbox`. ```json { "type": "boolean", "format": "checkbox" } ``` #### Arrays The default array editor takes up a lot of screen real estate. The `table` and `tabs` formats provide more compact UIs for editing arrays. The `table` format works great when every array element has the same schema and is not too complex. The `tabs` format can handle any array, but only shows one array element at a time. It has tabs on the left for switching between items. Here's an example of the `table` format: ```json { "type": "array", "format": "table", "items": { "type": "object", "properties": { "name": { "type": "string" } } } } ``` For arrays of enumerated strings, you can also use the `select` or `checkbox` format. These formats require a very specific schema to work: ```json { "type": "array", "uniqueItems": true, "items": { "type": "string", "enum": ["value1","value2"] } } ``` By default, the `checkbox` editor (multiple checkboxes) will be used if there are fewer than 8 enum options. Otherwise, the `select` editor (a multiselect box) will be used. You can override this default by passing in a format: ```json { "type": "array", "format": "select", "uniqueItems": true, "items": { "type": "string", "enum": ["value1","value2"] } } ``` #### Objects The default object layout is one child editor per row. The `grid` format will instead put multiple child editors per row. This can make the editor much more compact, but at a cost of not guaranteeing child editor order. ```json { "type": "object", "properties": { "name": { "type": "string" } }, "format": "grid" } ``` Editor Options ---------------- Editors can accept options which alter the behavior in some way. * `collapsed` - If set to true, the editor will start collapsed (works for objects and arrays) * `disable_array_add` - If set to true, the "add row" button will be hidden (works for arrays) * `disable_array_delete` - If set to true, all of the "delete" buttons will be hidden (works for arrays) * `disable_array_delete_all_rows` - If set to true, just the "delete all rows" button will be hidden (works for arrays) * `disable_array_delete_last_row` - If set to true, just the "delete last row" buttons will be hidden (works for arrays) * `disable_array_reorder` - If set to true, the "move up/down" buttons will be hidden (works for arrays) * `disable_collapse` - If set to true, the collapse button will be hidden (works for objects and arrays) * `disable_edit_json` - If set to true, the Edit JSON button will be hidden (works for objects) * `disable_properties` - If set to true, the Edit Properties button will be hidden (works for objects) * `enum_titles` - An array of display values to use for select box options in the same order as defined with the `enum` keyword. Works with schema using enum values. * `expand_height` - If set to true, the input will auto expand/contract to fit the content. Works best with textareas. * `grid_columns` - Explicitly set the number of grid columns (1-12) for the editor if it's within an object using a grid layout. * `hidden` - If set to true, the editor will not appear in the UI (works for all types) * `input_height` - Explicitly set the height of the input element. Should be a valid CSS width string (e.g. "100px"). Works best with textareas. * `input_width` - Explicitly set the width of the input element. Should be a valid CSS width string (e.g. "100px"). Works for string, number, and integer data types. * `remove_empty_properties` - If set to true for an object, empty object properties (i.e. those with falsy values) will not be returned by getValue(). ```json { "type": "object", "options": { "collapsed": true }, "properties": { "name": { "type": "string" } } } ``` You can globally set the default options too if you want: ```js JSONEditor.defaults.editors.object.options.collapsed = true; ``` Dependencies ------------------ Sometimes, it's necessary to have one field's value depend on another's. The `dependencies` keyword from the JSON Schema specification is not nearly flexible enough to handle most use cases, so JSON Editor introduces a couple custom keywords that help in this regard. The first step is to have a field "watch" other fields for changes. ```json { "type": "object", "properties": { "first_name": { "type": "string" }, "last_name": { "type": "string" }, "full_name": { "type": "string", "watch": { "fname": "first_name", "lname": "last_name" } } } } ``` The keyword `watch` tells JSON Editor which fields to watch for changes. The keys (`fname` and `lname` in this example) are alphanumeric aliases for the fields. The values (`first_name` and `last_name`) are paths to the fields. To access nested properties of objects, use a dot for separation (e.g. "path.to.field"). By default paths are from the root of the schema, but you can make the paths relative to any ancestor node with a schema `id` defined as well. This is especially useful within arrays. Here's an example: ```json { "type": "array", "items": { "type": "object", "id": "arr_item", "properties": { "first_name": { "type": "string" }, "last_name": { "type": "string" }, "full_name": { "type": "string", "watch": { "fname": "arr_item.first_name", "lname": "arr_item.last_name" } } } } } ``` Now, the `full_name` field in each array element will watch the `first_name` and `last_name` fields within the same array element. ### Templates Watching fields by itself doesn't do anything. For the example above, you need to tell JSON Editor that `full_name` should be `fname [space] lname`. JSON Editor uses a javascript template engine to accomplish this. A barebones template engine is included by default (simple `{{variable}}` replacement only), but many of the most popular template engines are also supported: * ejs * handlebars * hogan * markup * mustache * swig * underscore You can change the default by setting `JSONEditor.defaults.options.template` to one of the supported template engines: ```javascript JSONEditor.defaults.options.template = 'handlebars'; ``` You can set the template engine on a per-instance basis as well: ```js var editor = new JSONEditor(element,{ schema: schema, template: 'hogan' }); ``` Here is the completed `full_name` example using the default barebones template engine: ```js+jinja { "type": "object", "properties": { "first_name": { "type": "string" }, "last_name": { "type": "string" }, "full_name": { "type": "string", "template": "{{fname}} {{lname}}", "watch": { "fname": "first_name", "lname": "last_name" } } } } ``` ### Enum Values Another common dependency is a drop down menu whose possible values depend on other fields. Here's an example: ```json { "type": "object", "properties": { "possible_colors": { "type": "array", "items": { "type": "string" } }, "primary_color": { "type": "string" } } } ``` Let's say you want to force `primary_color` to be one of colors in the `possible_colors` array. First, we must tell the `primary_color` field to watch the `possible_colors` array. ```json { "primary_color": { "type": "string", "watch": { "colors": "possible_colors" } } } ``` Then, we use the special keyword `enumSource` to tell JSON Editor that we want to use this field to populate a drop down. ```json { "primary_color": { "type": "string", "watch": { "colors": "possible_colors" }, "enumSource": "colors" } } ``` Now, anytime the `possible_colors` array changes, the dropdown's values will be changed as well. This is the most basic usage of `enumSource`. The more verbose form of this property supports filtering, pulling from multiple sources, constant values, etc.. Here's a more complex example (this uses the Swig template engine syntax to show some advanced features) ```js+jinja { // An array of sources "enumSource": [ // Constant values ["none"], { // A watched field source "source": "colors", // Use a subset of the array "slice": [2,5], // Filter items with a template (if this renders to an empty string, it won't be included) "filter": "{% if item !== 'black' %}1{% endif %}", // Specify the display text for the enum option "title": "{{item|upper}}", // Specify the value property for the enum option "value": "{{item|trim}}" }, // Another constant value at the end of the list ["transparent"] ] } ``` You can also specify a list of static items with a slightly different syntax: ```js+jinja { "enumSource": [{ // A watched field source "source": [ { "value": 1, "title": "One" }, { "value": 2, "title": "Two" } ], "title": "{{item.title}}", "value": "{{item.value}}" }] ] } ``` The colors examples used an array of strings directly. Using the verbose form, you can also make it work with an array of objects. Here's an example: ```js+jinja { "type": "object", "properties": { "possible_colors": { "type": "array", "items": { "type": "object", "properties": { "text": { "type": "string" } } } }, "primary_color": { "type": "string", "watch": { "colors": "possible_colors" }, "enumSource": [{ "source": "colors", "value": "{{item.text}}" }] } } } ``` All of the optional templates in the verbose form have the properties `item` and `i` passed into them. `item` refers to the array element. `i` is the zero-based index. ### Dynamic Headers The `title` keyword of a schema is used to add user friendly headers to the editing UI. Sometimes though, dynamic headers, which change based on other fields, are helpful. Consider the example of an array of children. Without dynamic headers, the UI for the array elements would show `Child 1`, `Child 2`, etc.. It would be much nicer if the headers could be dynamic and incorporate information about the children, such as `1 - John (age 9)`, `2 - Sarah (age 11)`. To accomplish this, use the `headerTemplate` property. All of the watched variables are passed into this template, along with the static title `title` (e.g. "Child"), the 0-based index `i0` (e.g. "0" and "1"), the 1-based index `i1`, and the field's value `self` (e.g. `{"name": "John", "age": 9}`). ```js+jinja { "type": "array", "title": "Children", "items": { "type": "object", "title": "Child", "headerTemplate": "{{ i1 }} - {{ self.name }} (age {{ self.age }})", "properties": { "name": { "type": "string" }, "age": { "type": "integer" } } } } ``` ### Custom Template Engines If one of the included template engines isn't sufficient, you can use any custom template engine with a `compile` method. For example: ```js var myengine = { compile: function(template) { // Compile should return a render function return function(vars) { // A real template engine would render the template here var result = template; return result; } } }; // Set globally JSONEditor.defaults.options.template = myengine; // Set on a per-instance basis var editor = new JSONEditor(element,{ schema: schema, template: myengine }); ``` Language and String Customization ----------------- JSON Editor uses a translate function to generate strings in the UI. A default `en` language mapping is provided. You can easily override individual translations in the default language or create your own language mapping entirely. ```js+jinja // Override a specific translation JSONEditor.defaults.languages.en.error_minLength = "This better be at least {{0}} characters long or else!"; // Create your own language mapping // Any keys not defined here will fall back to the "en" language JSONEditor.defaults.languages.es = { error_notset: "propiedad debe existir" }; ``` By default, all instances of JSON Editor will use the `en` language. To override this default, set the `JSONEditor.defaults.language` property. ```js JSONEditor.defaults.language = "es"; ``` Custom Editor Interfaces ----------------- JSON Editor contains editor interfaces for each of the primitive JSON types as well as a few other specialized ones. You can add custom editors interfaces fairly easily. Look at any of the existing ones for an example. JSON Editor uses resolver functions to determine which editor interface to use for a particular schema or subschema. Let's say you make a custom `location` editor for editing geo data. You can add a resolver function to use this custom editor when appropriate. For example: ```js // Add a resolver function to the beginning of the resolver list // This will make it run before any other ones JSONEditor.defaults.resolvers.unshift(function(schema) { if(schema.type === "object" && schema.format === "location") { return "location"; } // If no valid editor is returned, the next resolver function will be used }); ``` The following schema will now use this custom editor for each of the array elements instead of the default `object` editor. ```json { "type": "array", "items": { "type": "object", "format": "location", "properties": { "longitude": { "type": "number" }, "latitude": { "type": "number" } } } } ``` If you create a custom editor interface that you think could be helpful to others, submit a pull request! The possibilities are endless. Some ideas: * A compact way to edit objects * Radio button version of the `select` editor * Autosuggest for strings (like enum, but not restricted to those values) * Better editor for arrays of strings (tag editor) * Canvas based image editor that produces Base64 data URLs Select2 & Selectize Support ---------------- Select2 support is enabled by default and will become active if the Select2 library is detected. Selectize support is enabled via the following snippet: ```js JSONEditor.plugins.selectize.enable = true; ``` See the demo for an example of the `array` and `select` editor with Selectize support enabled. Custom Validation ---------------- JSON Editor provides a hook into the validation engine for adding your own custom validation. Let's say you want to force all schemas with `format` set to `date` to match the pattern `YYYY-MM-DD`. ```js // Custom validators must return an array of errors or an empty array if valid JSONEditor.defaults.custom_validators.push(function(schema, value, path) { var errors = []; if(schema.format==="date") { if(!/^[0-9]{4}-[0-9]{2}-[0-9]{2}$/.test(value)) { // Errors must be an object with `path`, `property`, and `message` errors.push({ path: path, property: 'format', message: 'Dates must be in the format "YYYY-MM-DD"' }); } } return errors; }); ``` jQuery Integration ------------------- __*WARNING__: This style of usage is deprecated and may not be supported in future versions. When jQuery (or Zepto) is loaded on the page, you can use JSON Editor like a normal jQuery plugin if you prefer. ```js $("#editor_holder") .jsoneditor({ schema: {}, theme: 'bootstrap3' }) .on('ready', function() { // Get the value var value = $(this).jsoneditor('value'); value.name = "John Smith"; // Set the value $(this).jsoneditor('value',value); }); ```
