constructor and the core CSS:
import rangeSlider from 'range-slider-input';
import 'range-slider-input/dist/style.css';
CDN
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/rangeslider.umd.min.js"></script>
or
<script src="https://unpkg.com/range-slider-input@2"></script>
The core CSS comes bundled with the jsDelivr and unpkg imports.
Usage
import rangeSlider from 'range-slider-input';
import 'range-slider-input/dist/style.css';
const rangeSliderElement = rangeSlider(element);
API
rangeSlider(element, options = {})
Returns an object of functions that can be called to read or write the properties initially set by options
.
Parameters
element
options
Object that specifies the characteristics of the range slider element with the following available properties:
Return value
Object of functions that can be called to read or write the properties initially set by the options
parameter. Available functions:
min()
, max()
, step()
, value()
and orientation()
These are simple getter and setter functions. So, while calling these functions, if a parameter is supplied, the corresponding values will be set, and if a parameter is not supplied, the corresponding values will be returned.
E.g. Calling step()
will return the step
value, and calling value([0, 0.5])
will set the lower and upper offsets to 0
and 0.5
respectively.
disabled()
, rangeSlideDisabled()
The default parameter is set to true
. So, if they are called without a parameter, they will set the corresponding values to true
.
Thus, calling disabled()
or disabled(true)
will set options.disabled = true
and calling disabled(false)
will set options.disabled = false
.
thumbsDisabled()
The default parameter is set to [true, true]
. So, if it is called without a parameter, it will disable both thumbs. Example uses:
// thumbs -> lower upper
// ----- -----
thumbsDisabled() // disabled disabled
thumbsDisabled(true) // disabled disabled
thumbsDisabled(false) // enabled enabled
thumbsDisabled([]) // enabled enabled
thumbsDisabled([false]) // enabled enabled
thumbsDisabled([true]) // disabled enabled
thumbsDisabled([true, false]) // disabled enabled
thumbsDisabled([false, true]) // enabled disabled
thumbsDisabled([false, false]) // enabled enabled
thumbsDisabled([true, true]) // disabled disabled
currentValueIndex()
Returns the index (0
for the lower value and 1
for the upper value) of the value which is currently being modified.
Returns -1
when the slider is idle.
removeGlobalEventListeners()
Removes the global event listeners. It should be called when removing the range slider element from the DOM dynamically.
Elements
<div class="range-slider"><!-- range slider element -->
<input type="range" /><!-- hidden -->
<input type="range" /><!-- hidden -->
<div class="range-slider__thumb" data-lower></div>
<div class="range-slider__thumb" data-upper></div>
<div class="range-slider__range"></div>
</div>
<div class="range-slider"></div>
is the wrapper element that was used to instantiate the range slider initially and is added with a CSS class named range-slider
.
<input type="range" />
elements are used to set values and are hidden.
<div class="range-slider__thumb"></div>
elements are the slidable thumbs replacing the original thumbs from the <input type="range" />
elements.
<div class="range-slider__range"></div>
element fills up the space between the thumbs.
