Readme

cordova-plugin-keyboard
This plugin provides the Keyboard object which has some functions to customize and control the keyboard. It also supports the HideKeyboardFormAccessoryBar (boolean) and KeyboardShrinksView (boolean) preferences in config.xml.

This plugin has only been tested in Cordova 3.2 or greater, and its use in previous Cordova versions is not recommended (potential conflict with keyboard customization code present in the core in previous Cordova versions).
If you do use this plugin in an older Cordova version (again, not recommended), you have to make sure the HideKeyboardFormAccessoryBar and KeyboardShrinksView preference values are always false, and only use the API functions to turn things on/off.
This plugin was based on this Apache project and has a compatible API.

Methods

Keyboard.shrinkView

Shrink the WebView when the keyboard comes up.
Keyboard.shrinkView(value, successCallback);

Description

Set to true to shrink the WebView when the keyboard comes up. The WebView shrinks instead of the viewport shrinking and the page scrollable. This applies to apps that position their elements relative to the bottom of the WebView. This is the default behaviour on Android, and makes a lot of sense when building apps as opposed to webpages.

Supported Platforms

  • iOS

Keyboard.shrinkView(true);
Keyboard.shrinkView(false);
Keyboard.shrinkView(null, function (currentValue) { console.log(currentValue); });
