paper-range-slider - v3.0.0
paper-range-slider allows the user to select a range of values within a given (possibly wider) range. values are selected by moving the position of two knobs, or by dragging the selected range of values within the allowed limits. paper-range-slider - v1.* is compatible with Polymer v2.* (For Polymer v1.*, use paper-range-slider - v0.2.7.)

npm installation

Do either
npm i paper-range-slider
or add the following to your package.json:
"dependencies": {
  "paper-range-slider": "^3.0.0"


Basic use:


Additional options

  • Use min and max to specify the limits of values for the slider (the lower and upper bounds).
  • Use value-min and value-max to set the initial position of the two knobs (the selected range of values).
  • Use value-diff-min and value-diff-max to set the minimal and maximal allowed difference between the lower and upper selected values.
  • Use always-show-pin to never hide the pins.
  • The following options apply, as for paper-slider: snaps, pin, step, disabled.

```html ```
  • The current position of the knobs (selected range of values) may be accessed by setting up a listener to the updateValues event:

```html ```
  • One can programmatically set the selected range by e.g.,
```javascript window.addEventListener('WebComponentsReady', function(e) {
var myMin = 10, myMax = 90, myEventName = 'setValues';
}); `` The third argument (myEventName) is an optional event name, which will be propagated to e.g., on-value-min-changed` events. It is allowed to set myMin and/or myMax to null or to a value outside of the allowed range, in order to ignore them, e.g., use the following to only change the lower value: ```javascript document.querySelector("#myPaperRangeSliderId").setValues(10,null); ```
  • Likewise, one can set the minimal and maximal values of the slider (the lower and upper bounds), the step-size, the minimal and maximal difference between selected values, and the disabled state. These correspond respectively to the following:
```javascript document.querySelector("#myPaperRangeSliderId").setMin(myMin); document.querySelector("#myPaperRangeSliderId").setMax(myMax); document.querySelector("#myPaperRangeSliderId").setStep(myStep); document.querySelector("#myPaperRangeSliderId").setValueDiffMin(myValueDiffMin); document.querySelector("#myPaperRangeSliderId").setValueDiffMax(myValueDiffMax); document.querySelector("#myPaperRangeSliderId").setDisabled(isDisabled); ```
  • One can get the ratio of the current slider values in percent (within [0,1]) by e.g.,
var ratioMinMax = document.querySelector("#myPaperRangeSliderId").getRatio();
  • The tapValueExtend, tapValueReduce and tapValueMove properties control what happens when a user taps the slider (not e.g., relevant for when the user drags the selected range). The tapValueExtend property (true by default) allows to modify the selected range of values, by tapping on the slider below or above the selected range. On the other hand, tapValueReduce (false by default) allows to modify the selected range of values, by tapping on the slider within the selected range. Finally tapValueMove supersedes the tapValueExtend and tapValueReduce properties if set (it is false by default). If tapValueMove is enabled, tapping the slider will update the selected range, while keeping the same difference between valueMin and valueMax. One may set these properties by e.g.,

``` or programmatically with ```javascript document.querySelector("#myPaperRangeSliderId").setTapValueExtend(isTapValueExtend); document.querySelector("#myPaperRangeSliderId").setTapValueReduce(isTapValueReduce); document.querySelector("#myPaperRangeSliderId").setTapValueMove(isTapValueMove); ```
  • The above properties which do not have an explicit method, may be reset directly. In order for the changes to take effect properly, use the init() method. For instance, to change the alwaysShowPin option of an already-defined slider, do:
```javascript document.querySelector("#myPaperRangeSliderId").alwaysShowPin = true; document.querySelector("#myPaperRangeSliderId").init(); ```
  • It is possible to "revert" the paper-range-slider into a paper-slider (and back again) by

```html ```
or programmatically with ```javascript document.querySelector("#myPaperRangeSliderId").setSingleSlider(isSingleSlider); ``` In this case, the minimal value of the range is effectively ignored. The value of the single slider may now be manipulated with e.g., ```javascript // set a new value for the single slider var setVal = 90; document.querySelector("#myPaperRangeSliderId").setValues(null,setVal); // get the current value of the single slider var valNow = document.querySelector("#myPaperRangeSliderId").valueMax; ```
