Common issues

My slider is not rendered correctly on load

If the slider's parent element is not visible during slider initialization, the slider can't know when its parent becomes visible. For instance, when displaying a slider inside an element which visibility is toggled using ng-show, you need to send an event to force it to redraw when you set your ng-show to true.

Here's an example of refreshSlider method that you should call whenever the slider becomes visible.

vm.refreshSlider = function () {
    $timeout(function () {
        $scope.$broadcast('rzSliderForceRender');
    });
};

Installation

NPM

npm i angularjs-slider

or

Bower

$ bower install --save angularjs-slider

or

CDNJS

Directly use:

https://cdnjs.cloudflare.com/ajax/libs/angularjs-slider/2.5.0/rzslider.min.js
https://cdnjs.cloudflare.com/ajax/libs/angularjs-slider/2.5.0/rzslider.min.css

Module

angular.module('yourApp', ['rzModule']);

Single slider

// In your controller
$scope.priceSlider = 150;

<div>
    <rzslider rz-slider-model="priceSlider"></rzslider>
</div>

Above example would render a slider from 0 to 150. If you need floor and ceiling values use rz-slider-options attribute and provide an object with floorand ceil.

<div>
    <rzslider
         rz-slider-model="slider.value"
         rz-slider-options="slider.options"></rzslider>
</div>

$scope.slider = {
  value: 150,
  options: {
    floor: 0,
    ceil: 450
  }
};

If you don't want to bother with an object set in your javascript file, you can pass an anonymous object literal to the slider options:

<div>
    <rzslider
         rz-slider-model="value"
         rz-slider-options="{floor: 0, ceil: 450}"></rzslider>
</div>

$scope.value = 150;

Range slider

// In your controller
$scope.slider = {
  min: 100,
  max: 180,
  options: {
    floor: 0,
    ceil: 450
  }
};

<rzslider
    rz-slider-model="slider.min"
    rz-slider-high="slider.max"
    rz-slider-options="slider.options"></rzslider>

Directive attributes

rz-slider-model

Model for low value slider. If only rz-slider-model is provided single slider will be rendered.

rz-slider-high

Model for high value slider. Providing both rz-slider-model and rz-slider-high will render range slider.

rz-slider-options

An object with all the other options of the slider. Each option can be updated at runtime and the slider will automatically be re-rendered.

The default options are:

{
    floor: 0,
    ceil: null, //defaults to rz-slider-model
    step: 1,
    precision: 0,
    minRange: 0,
    id: null,
    translate: null,
    stepsArray: null,
    draggableRange: false,
    draggableRangeOnly: false,
    showSelectionBar: false,
    showSelectionBarEnd: false,
    hideLimitLabels: false,
    readOnly: false,
    disabled: false,
    interval: 350,
    showTicks: false,
    showTicksValues: false,
    ticksTooltip: null,
    ticksValuesTooltip: null,
    vertical: false,
    selectionBarColor: null,
    keyboardSupport: true,
    scale: 1,
    enforceRange: false,
    noSwitching: false,
    onlyBindHandles: false,
    onStart: null,
    onChange: null,
    onEnd: null
}

floor - Number (defaults to 0): Minimum value for a slider.

ceil - Number (defaults to rz-slider-modelvalue): Maximum value for a slider.

step - Number (defaults to 1): Step between each value.

precision - Number (defaults to 0): The precision to display values with. The toFixed() is used internally for this.

minRange - Number (defaults to 0): The minimum range authorized on the slider. Applies to range slider only.

translate - Function(value, sliderId): Custom translate function. Use this if you want to translate values displayed on the slider. For example if you want to display dollar amounts instead of just numbers:

<div>
    <rzslider
         rz-slider-model="slider.value"
         rz-slider-options="slider.options"></rzslider>
</div>

$scope.slider = {
  value: 0,
  options: {
    floor: 0,
    ceil: 100,
    translate: function(value) {
      return '$' + value;
    }
  }
};

id - Any (defaults to null): If you want to use the same translate function for several sliders, just set the id to anything you want, and it will be passed to the translate(value, sliderId) function as a second argument.

stepsArray - Array: If you want to display a slider with non linear/number steps. Just pass an array with each slider value and that's it; the floor, ceil and step settings of the slider will be computed automatically. The rz-slider-model value will be the index of the selected item in the stepsArray.

draggableRange - Boolean (defaults to false): When set to true and using a range slider, the range can be dragged by the selection bar. Applies to range slider only.

draggableRangeOnly - Boolean (defaults to false): Same as draggableRange but the slider range can't be changed. Applies to range slider only.

showSelectionBar - Boolean (defaults to false): Set to true to always show the selection bar before the slider handle.

showSelectionBarEnd - Boolean (defaults to false): Set to true to always show the selection bar after the slider handle.

getSelectionBarColor - Function(value) or Function(minVal, maxVal) (defaults to null): Function that returns the current color of the selection bar. If the returned color depends on a model value (either rzScopeModelor 'rzSliderHigh), you should use the argument passed to the function. Indeed, when the function is called, there is no certainty that the model has already been updated.

hideLimitLabels - Boolean (defaults to false): Set to true to hide min / max labels

readOnly - Boolean (defaults to false): Set to true to make the slider read-only.

disabled - Boolean (defaults to false): Set to true to disable the slider.

interval - Number in ms (defaults to 350): Internally, a throttle function (See http://underscorejs.org/#throttle) is used when the model or high values of the slider are changed from outside the slider. This is to prevent from re-rendering the slider too many times in a row. interval is the number of milliseconds to wait between two updates of the slider.

showTicks - Boolean (defaults to false): Set to true to display a tick for each step of the slider.

showTicksValues - Boolean (defaults to false): Set to true to display a tick and the step value for each step of the slider.

ticksTooltip - Function(value) (defaults to null): (requires angular-ui bootstrap) Used to display a tooltip when a tick is hovered. Set to a function that returns the tooltip content for a given value.

ticksValuesTooltip - Function(value) (defaults to null): Same as ticksTooltip but for ticks values.

scale - Number (defaults to 1): If you display the slider in an element that uses transform: scale(0.5), set the scale value to 2 so that the slider is rendered properly and the events are handled correctly.

enforceRange - Boolean (defaults to false): Set to true to round the rzSliderModel and rzSliderHigh to the slider range even when modified from outside the slider. When set to false, if the model values are modified from outside the slider, they are not rounded but they are still rendered properly on the slider.

noSwitching - Boolean (defaults to false): Set to true to prevent to user from switching the min and max handles. Applies to range slider only.

onlyBindHandles - Boolean (defaults to false): Set to true to only bind events on slider handles.

onStart - Function(sliderId, modelValue, highValue): Function to be called when a slider update is started. If an id was set in the options, then it's passed to this callback. This callback is called before any update on the model.

onChange - Function(sliderId, modelValue, highValue): Function to be called when rz-slider-model or rz-slider-high change. If an id was set in the options, then it's passed to this callback.

onEnd - Function(sliderId, modelValue, highValue): Function to be called when a slider update is ended. If an id was set in the options, then it's passed to this callback.

vertical - Boolean (defaults to false): Set to true to display the slider vertically. The slider will take the full height of its parent. Changing this value at runtime is not currently supported.

keyboardSupport - Boolean (defaults to true): Handles are focusable (on click or with tab) and can be modified using the following keyboard controls:

Left/bottom arrows: -1
Right/top arrows: +1
Page-down: -10%
Page-up: +10%
Home: minimum value
End: maximum value

Change default options

If you want the change the default options for all the sliders displayed in your application, you can set them using the RzSliderOptions.options() method:

angular.module('App', ['rzModule'])
	.run(function( RzSliderOptions ) {
		// show ticks for all sliders
		RzSliderOptions.options( { showTicks: true } );
	});

Slider events

To force slider to recalculate dimensions, broadcast reCalcViewDimensions event from parent scope. This is useful for example when you use slider inside a widget where the content is hidden at start - see the "Sliders into modal" example on the demo site.

You can also force redraw with rzSliderForceRender event.

At the end of each "slide" slider emits slideEnded event.

$scope.$on("slideEnded", function() {
     // user finished sliding a handle
});

Project integration

    <link rel="stylesheet" type="text/css" href="/path/to/slider/rzslider.css"/>
    <script src="/path/to/angularjs/angular.min.js"></script>
    <script src="/path/to/slider/rzslider.min.js"></script>

    <script>
        var YourApp = angular.module('myapp', ['rzModule']);
    </script>

Browser support

I use Slider on couple of my projects and it's being tested on desktop versions of Chrome, Firefox, Safari, IE 9/10 (Ticks are displayed using flex display so they don't work on IE9). Slider is also tested on Android and iPhone using all browsers available on those platforms.
