bootstrap-slider

Originally began as a loose "fork" of bootstrap-slider found on http://www.eyecon.ro/ 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!!

Installation

Clone the repository, then run npm install

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

Want to use npm? npm install bootstrap-slider

Then 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!

Examples

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
	mySlider
		.slider('setValue', 5)
		.slider('setValue', 7);

If there is already a JQuery plugin named slider bound to the 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
	mySlider
		.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
mySlider
	.setValue(5)
	.setValue(7);

Loading as CommonJS module

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

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

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
precision	float	number of digits after the decimal of step value	The number of digits shown after the decimal. Defaults to the number of digits after the decimal of step value.
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.
selection	string	'before'	selection placement. Accepts: 'before', 'after' or 'none'. In case of a range slider, the selection will be placed between the handles
tooltip	string	'show'	whether to show the tooltip on drag, hide the tooltip, or always show the tooltip. Accepts: 'show', 'hide', or 'always'
tooltip_split	bool	false	if false show one tootip if true show two tooltips one for each handler
handle	string	'round'	handle shape. Accepts: 'round', 'square', 'triangle' or 'custom'

natural_arrow_keys	bool	false	The natural order is used for the arrow keys. 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.

Functions

NOTE: Optional parameters are italicized.
