bootstrap-slider Build Status

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

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

Want to use npm? npm install bootstrap-slider

Want to get it from a CDN? https://cdnjs.com/libraries/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!

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);

Using bootstrap-slider (via data-provide-API)

Create an input element with the data-provide="slider" attribute automatically turns it into a slider. Options can be supplied via data-slider- attributes.

<input
	type="text"
	name="somename"
	data-provide="slider"
	data-slider-ticks="[1, 2, 3]"
	data-slider-ticks-labels='["short", "medium", "long"]'
	data-slider-min="1"
	data-slider-max="3"
	data-slider-step="1"
	data-slider-value="3"
	data-slider-tooltip="hide"
>

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
	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);

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

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
tooltip_position string null Position of tooltip, relative to slider. Accepts 'top'/'bottom' for horizontal sliders and 'left'/'right' for vertically orientated sliders. Default positions are 'top' for horizontal and 'right' for vertical slider.
handle string 'round' handle shape. Accepts: 'round', 'square', 'triangle' or 'custom'
reversed bool false whether or not the slider should be reversed
enabled bool true whether or not the slider is initially enabled
formatter function returns the plain value formatter callback. Return the value wanted to be displayed in the tooltip
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.
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 always be 0, the last value should always be 100 percent.
ticks_labels array [ ] Defines the labels below the tick marks. Accepts HTML input.
ticks_snap_bounds float 0 Used to define the snap bounds of a tick. Snaps to the tick if value is within these bounds.
scale string 'linear' Set to 'logarithmic' to use a logarithmic scale.
focus bool false Focus the appropriate slider handle after a value change.
labelledby string,array null ARIA labels for the slider handle's, Use array for multiple values in a range slider.

Functions

How Do I Run This Locally?

  • Clone the repository
  • Run nvm use in your Terminal to switch to the proper Node/NPM version
  • Once you are on specified Node version, run npm install
  • Install the Grunt CLI: npm install grunt-cli -g
  • Type grunt dev to launch browser window with Examples page

Grunt Tasks

This plugin uses Grunt as its command-line task runner.

To install the Grunt CLI, type npm install grunt-cli -g.

To execute any of the commands, type grunt <task-name> in your terminal instance.

The following is a list of the commonly-used command line tasks:

  • grunt development: Generates the index.html, compiles the LESS/JS to the /temp directory, and launches the index.html in your system's default browser. As changes are made to source code, the browser window will auto-refresh.
  • grunt production: Generates the /dist directory with minified and unminified assetts.
  • grunt dev: Alias for grunt development
  • grunt prod: Alias for grunt production
  • grunt build: Transpiles JavaScript source via Babel and compiles LESS source to CSS to temp directory.
  • grunt lint: Runs JSLint on the JavaScript source code.
  • grunt test: Runs unit tests contained in /test directory via Jasmine.

Version Bumping and Publishing (Maintainers Only)

To bump the version number across all the various packagement systems the plugin is registered with, please use the grunt bump plugin.

  • grunt bump:patch - patch version bump, 0.0.0 -> 0.0.1
  • grunt bump:minor - minor version bump, 0.0.0 -> 0.1.0
  • grunt bump:major - major version bump, 0.0.0 -> 1.0.0
