ui-rangebar

AngularJS directive for Elessar.js

Draggable multiple range sliders

Installation

Install ui-rangebar via npm or bower:

npm install ui-rangebar | bower install ui-rangebar ----------------------|------------------------

<script src="path/to/elessar.css"></script>

<script src="path/to/elessar.js"></script>
<script src="path/to/angular.js"></script>
<script src="path/to/ui.rangebar.js"></script>

Simple Usage

1. Reference ui-rangebar to angularjs:

angular.module("app", ["ui.rangebar"]);

2. Add in your html page

<ui-rangebar ng-model="bar.ranges"></ui-rangebar>

Usage with options

<ui-rangebar ng-model="bar.ranges" ui-options="options"></ui-rangebar>

In addition to Elessar options

syncOnChanging:false, //Sync ngModel on 'changing' event
model: {
   bind: {
      startProp: "", //Name of property to be bound for start of range
      endProp: "", //Name of property to be bound for end of range
      totalSize: "" //Name of property for total size of the range
      valuesKeyPath: "", //Path to values array ex. person.intervals. Useful for nested objects
   },
   formatter: fn //a function that returns start and end range as array in a format that will be bound to ngModel
},
addrange: function (range, bar, index){},//Event raised when new range is added
changing: function (ev, range, bar) {},
change: function (ev, ranges, changed) {},
click: function (ev, bar, index) {},
mouseenter: function (ev, bar, index) {},
mouseleave: function (ev, bar, index) {},
mousedown: function (ev, bar, index) {},
mouseup: function (ev, bar, index) {},

Update selected range explicitly

Note:

Following cases apply only in case ngModel is updated/removed explicitly. Otherwise it's sufficient to add or remove item from ngModel array and changes will be reflected. See demos!

In case ngModel is changed by an external source such as popover/popup, you might need to force update for the selected bar.

bar.update(); //bar - selected range obj, can be fetched from any event, typically from click event

// @newModel: optional parameter.
bar.update(newModel); //Recommended

Remove selected range explicitly

bar.delete();

Advance Example

Example with nested values. Set, add and remove from ngModel.

Following example could be done much easier using momentjs. This is just for demostration purpose.

Controller.js

(function (app) {

    app.controller("HomeController", [HomeController])
    function HomeController() {
        var vm = this;
        var counter = 0;
        var baseName = "X_";
        var sampleModel = {name: "Interval X", startTime: "04:10:00", endTime: "06:10:00"};
        var values = {
            name: "Main object",
            intervals: [

        function timeToMinutes(time) {

            }
        }

• uiRangebarConfigProvider:

Configure default options for the whole application

Note: Configuration from attributes or controller will have priority against config provider.

angular.module("app", ["ui.rangebar"])
    .config(function (uiRangebarConfigProvider) {
        var defaults = {
            syncOnChanging:true,
            min: 0,
            max: 100,
            rangeClass: "someClass"
        };
        uiRangebarConfigProvider.setOptions(defaults);
});

• uiInstance:

Instance of rangebar object. Avoid using it for add/remove operations since it might not syncronize with ngModel. Use it for readonly purpose!

$scope.rangeBarInstance = {};

<ui-rangebar ng-model="values" ui-options="options" ui-instance="rangeBarInstance"></ui-rangebar>
