angular-rangeslider

Current version: 0.0.14

Angular RangeSlider is a directive that creates an interactive slider that allows a user to change model values.

It has been styled to match form elements styled by Twitter's Bootstrap CSS framework.

Requirements

• Angular (v1.0.8+)
• jQuery (v1.7+)

Looking for collaborators

This directive was written for a project completed way back in 2013. I've not needed to use it since and have no plans (or time) to continue development / maintenance.

I'm sure there are better rangesliders out there these days.

If anyone would like to become a collaborator please let me know: @iamdanielcrisp

Installation

Download the files from Github or use Bower:

$ bower install angular-rangeslider

Add the JS and CSS to your page:

<script src="bower_components/angular-rangeslider/angular.rangeSlider.js"></script>
<link rel="stylesheet" href="bower_components/angular-rangeslider/angular.rangeSlider.css">

Add the ui-rangeSlider module as a dependency for your app: angular.module('myApp', ['ui-rangeSlider']);

Bootstrap is not required.

If you use SCSS & Compass you can include the source SCSS directly into your project CSS if you add bower_components to your include path:

@import "angular-rangeslider/scss/rangeSlider"; // requires Compass

Demo

• Demo - Angular v.1.1.*
• Legacy Demo - Angular v.1.0.*

Quick example

A basic slider with a range of 0 to 100:

<div range-slider min="0" max="100" model-min="min" model-max="max"></div>

As the handles are moved the model values min and max will be updated in the parent controller.

Options

Options are set as attributes on the <div range-slider>

= two-way bindings

min - the minimum value the user can select (must be a number, can be a model property)

max - the maximum value the user can select (must be a number, can be a model property)

model-min - the model property for the min value, represents the position of the min handle

model-max - the model property for the max value, represents the position of the max handle

disabled - model property or boolean, disables the slider when true

@ attributes

orientation - slider orientation, default: 'horizontal' - options: 'horizontal' | 'vertical' | 'vertical left' | 'vertical right'

step - amount to change the value by when moving a handle, default: 0

decimal-places - the number of decimal places to round to, default: 0

filter - a built-in filter to apply to the displayed values, for example currency or currency:'$'

filter-options - options to pass to the filter

pin-handle - disable/hide one handle, default: null - options: 'min' | 'max'

prevent-equal-min-max - prevent the min and max values from being equal. The step value is used to set the minimum difference, otherwise a value of 1 is used.

attach-handle-values - move the value labels in sync with the slider handles when true, default: false

on-handle-up - call a function whenever a handle is released

on-handle-down - call a function whenever a handle is grabbed

getter-setter - enable getter / setter support for model values - options: true | false

Some more examples

Using model properties

The following properties are present in the scope:

// set available range
$scope.minPrice = 100;
$scope.maxPrice = 999;

// default the user's values to the available range
$scope.userMinPrice = $scope.minPrice;
$scope.userMaxPrice = $scope.maxPrice;

So we can include the directive in the HTML like this:

<div range-slider min="minPrice" max="maxPrice" model-min="userMinPrice" model-max="userMaxPrice" step="5"></div>

As the user moves the min and max handles the userMinPrice and userMaxPrice will be updated in increments of 5 in real-time in the model.

Using filters

Continuing from the example above we can format the values displayed to the user as currency.

<div range-slider min="minPrice" max="maxPrice" model-min="userMinPrice" model-max="userMaxPrice" step="5" filter="currency"></div>

This will automatically be localised by Angular, but we can force it to be USD by passing this as an option:

<div range-slider min="minPrice" max="maxPrice" model-min="userMinPrice" model-max="userMaxPrice" step="5" filter="currency" filter-options="USD$"></div>

Alternatively you can use Angular's filter notation directly in the filter attribute, such as filter="currency:'GBP £'", which would result in values like this: GBP £7,500.00.

<div range-slider min="minPrice" max="maxPrice" model-min="userMinPrice" model-max="userMaxPrice" step="5" filter="currency:'GBP £'"></div>

NOTE: If the filter-options attribute is defined you cannot use Angular filter notation. You must only use the filter name in the filter attribute.

Making the slider vertical

Simply add one of the following values to the orientation attribute: 'vertical', 'vertical left' or 'vertical right'.

This will create a vertical slider that is centred in it's parent element:

<div range-slider min="0" max="100" model-min="min" model-max="max" orientation="vertical"></div>

To left-align the slider use 'vertical left':

<div range-slider min="0" max="100" model-min="min" model-max="max" orientation="vertical left"></div>

And to right-align the slider use 'vertical right':

<div range-slider min="0" max="100" model-min="min" model-max="max" orientation="vertical right"></div>

Disabling the slider

If you have a boolean property in your scope you can simply change this value to true to disable the slider:

$scope.sliderDisabled = false;

And then specify the property using the disabled attribute:

<div range-slider min="0" max="100" model-min="min" model-max="max" disabled="sliderDisabled"></div>

// clicking this button will toggle the sliderDisabled value between true and false
<button ng-click="sliderDisabled=!sliderDisabled">Toggle slider disabled status</button>

Pinning a handle

If you would like only allow setting one value, effectively creating a single-value silder, set the pin-handle attribute to 'min' or 'max'. You may then omit the corresponding model-xxx property:

<div range-slider min="0" max="100" model-max="max" pin-handle="min></div>

Move values with handles

Set the attach-handle-values attribute to true to have the values move with the slider handles. This works for either horizontal:

<div range-slider min="0" max="100" model-min="min" model-max="max" attach-handle-values="true"></div>

or vertical:

<div range-slider min="0" max="100" model-min="min" model-max="max" attach-handle-values="true" orientation="vertical"></div>

Angular 1.0.* Support

If you use this directive with an older version of Angular (e.g. v1.0.*) then the directive automatically detects this and switches on legacy support.

This basically changes the optional isolate scope properties disabled, modelMin and modelMax so that they are no longer optional and must always be defined on the directive element.

So, this would give an error (Error: Non-assignable model expression: undefined (directive: rangeSlider)) if you were using Angular v1.0.8:

<div range-slider min="0" max="100" model-min="demo1.min" model-max="demo1.max"></div>

However this would work correctly:

<div range-slider min="0" max="100" model-min="demo1.min" model-max="demo1.max" disabled="false"></div>

Note, only tested in v1.0.8

To Do

• Remove full jQuery dependency
• Improve behaviour when model values are not valid (e.g. min is greater than max)
• Improve the dev architecture (add jshint, tests, minification, auto-versioning etc)

Known Issues

• The slider restricts the model value when editing outside the slider (e.g. in an ) but the only notification is made to the console
• The min slider handle disappears behind the max slider handle
