Originally began as a loose "fork" of bootstrap-slider found on by Stefan Petre.

Over time, this project has diverged sigfinicantly from Stefan Petre's version and is now almost completly different.

Please ensure that you are using this library instead of the Petre version before creating issues in the repository Issue tracker!!


Clone the repository, then run npm install

Want to use bower? bower install seiyria-bootstrap-slider

Want to use npm? npm install bootstrap-slider

NOTE for NPM users: In order to keep the version numbers in our dist/ file consistent with our Github tags, we do a patch version bump, generate a new dist, and create a commit/tag on postpublish.

This does mean the Github repo will always be one patch commit off of what is published to NPM. Note that this will not affect functionality, and is only used to keep package management system files and the dist file version numbers in sync.

Basic Setup

Load the plugin CSS and JavaScript into your web page, and everything should work!

Remember to load the plugin code after loading the Bootstrap CSS and JQuery.

JQuery is optional and the plugin can operate with or without it.

Look below to see an example of how to interact with the non-JQuery interface.

Supported Browsers

We only support modern browsers!!! Basically, anything below IE9 is not compatible with this plugin!


You can see all of our API examples here.

Using bootstrap-slider (with JQuery)

Create an input element and call .slider() on it:

// Instantiate a slider
var mySlider = $("input.slider").slider();

// Call a method on the slider
var value = mySlider.slider('getValue');

// For non-getter methods, you can chain together commands
		.slider('setValue', 5)
		.slider('setValue', 7);

What if there is already a slider plugin bound to the JQuery namespace?

If there is already a JQuery plugin named slider bound to the JQuery namespace, then this plugin will take on the alternate namespace bootstrapSlider.

// Instantiate a slider
var mySlider = $("input.slider").bootstrapSlider();

// Call a method on the slider
var value = mySlider.bootstrapSlider('getValue');

// For non-getter methods, you can chain together commands
		.bootstrapSlider('setValue', 5)
		.bootstrapSlider('setValue', 7);

Using bootstrap-slider (without JQuery)

Create an input element in the DOM, and then create an instance of Slider, passing it a selector string referencing the input element.

// Instantiate a slider
var mySlider = new Slider("input.slider", {
	// initial options object

// Call a method on the slider
var value = mySlider.getValue();

// For non-getter methods, you can chain together commands

Using as CommonJS module

bootstrap-slider can be loaded as a CommonJS module via Browserify, Webpack, or some other build tool.

var Slider = require("bootstrap-slider");

var mySlider = new Slider();

Note that the JQuery dependency is considered to be optional. For example, to exclude JQuery from being part of your Browserify build, you would call something like the following (assuming main.js is requiring bootstrap-slider as a dependency):

browserify -u jquery main.js > bundle.js

Please see the documentation for the specific CommonJS loader you are using to find out how to exclude dependencies.


Options can be passed either as a data (data-slider-foo) attribute, or as part of an object in the slider call. The only exception here is the formatter argument - that can not be passed as a data- attribute.

Name Type Default Description
id string '' set the id of the slider element when it's created
min float 0 minimum possible value
max float 10 maximum possible value
step float 1 increment step

orientation string 'horizontal' set the orientation. Accepts 'vertical' or 'horizontal'
value float,array 5 initial value. Use array to have a range slider.
range bool false make range slider. Optional if initial value is an array. If initial value is scalar, max will be used for second value.

Arrow up select the upper slider value for vertical sliders, arrow right the righter slider value for a horizontal slider - no matter if the slider was reversed or not. By default the arrow keys are oriented by arrow up/right to the higher slider value, arrow down/left to the lower slider value.
ticks array [ ] Used to define the values of ticks. Tick marks are indicators to denote special values in the range. This option overwrites min and max options.
ticks_positions array [ ] Defines the positions of the tick values in percentages. The first value should alwasy be 0, the last value should always be 100 percent.
ticks_labels array [ ] Defines the labels below the tick marks. Accepts HTML input.
