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 completely different.
Please ensure that you are using this library instead of the Petre version before creating issues in the repository issue tracker!!
Note also that Bootstrap 4 is not yet supported, see issue #689.
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
Basic Setup
Grab the compiled JS/CSS (minified or non-minified versions) from the /dist directory, load them 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)
Using .slider
namespace
Create an input element and call .slider() on it:
var mySlider = $("input.slider").slider();
var value = mySlider.slider('getValue');
mySlider
.slider('setValue', 5)
.slider('setValue', 7);
Using .bootstrapSlider
namespace
Create an input element and call .bootstrapSlider() on it:
var mySlider = $("input.slider").bootstrapSlider();
var value = mySlider.bootstrapSlider('getValue');
mySlider
.bootstrapSlider('setValue', 5)
.bootstrapSlider('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 provide an alternative namespace bootstrapSlider and will emit a console warning telling you the slider namespace has already been taken and will encourage you to use the alternate namespace instead. If the slider namespace is available however, the bootstrapSlider namespace will not exist.
var mySlider = $("input.slider").bootstrapSlider();
var value = mySlider.bootstrapSlider('getValue');
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.
var mySlider = new Slider("input.slider", {
});
var value = mySlider.getValue();
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();
How do I exclude the optional JQuery dependency from my build?
Browserify
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 --im -u jquery main.js > bundle.js
Webpack
To exclude JQuery from your Webpack build, you will have to go into the Webpack config file for your specific project and add something like the following to your resolve.alias
section:
resolve: {
alias: {
"jquery": path.join(__dirname, "./jquery-stub.js")
}
}
Then in your project, you will have to create a stub module for jquery that exports a null
value. Whenever require("jquery")
is mentioned in your project, it will load this stubbed module.
module.exports = null;
Other
Please see the documentation for the specific module 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 |
rtl | bool | string | 'auto' |
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, useful for string values. If a string is returned it will be indicated in an aria-valuetext attribute. |
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. |
ticks_tooltip | bool | false | Used to allow for a user to hover over a given tick to see it's value. Useful if custom formatter passed in |
scale | string | 'linear' | Set to 'logarithmic' to use a logarithmic scale. Logarithmic scales will be calculated based on the difference between min to max; e.g. (0..10000) (-100..9900) both have a net range of 10001 and will slide in the same net increments. |
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. |
rangeHighlights | array | [] | Defines a range array that you want to highlight, for example: [{'start':val1, 'end': val2, 'class': 'optionalAdditionalClassName'}]. |

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 files, SASS-Lint on the SASS source code files, and LESSLint on the LESS source code files.grunt test
: Runs unit tests contained in /test
directory via Jasmine 2.x.x
Version Bumping and Publishing (Maintainers Only)
For versioning rules, we follow the Semver convention.
To do the following release tasks:
- bump the version
- publish a new version to NPM
- update the
gh-pages
branch - push a new
dist
bundle to the master
branch on the remote origin
- push new tags to the remote
origin
Type the following command:
npm run release <patch|minor|major>
If you do not specify a version bump type, the script will automatically defer to a patch bump.
Updating Github.io Page
The Github.io page can be automatically updated by running the following command:
npm run update-gh-pages
This command will handle generating the latest versions of the JS/CSS and index.html page, and push them to the gh-pages
branch.
