Text

It specifies the text content of the tag. The value set to this property is string type.

URL

This property specifies the URL for an image. The value set to this property is string type.

Query

This property retrieves data from remote data. This property is applicable only when a remote data source is used. Each data value is used to render an item for the Rotator. The value set to this property is object type.

Local data binding

Rotator provides the data binding support for the Rotator item. So you can bind the data from JSON Data. For this behavior, you need to map the corresponding filed with their column names. The data can be bound as a list and it is assigned to dataSource property. You can refer the following code example to bind local data.

  • html
  • <div class="cols-sample-area">
      <ul id="sliderContent"></ul>
    </div>
  • javascript
  • /// <reference path="../tsfiles/jquery.d.ts" />
     /// <reference path="../tsfiles/ej.web.all.d.ts" />\
    
    module RotatorComponent {
        $(function () {
            var website = [
          { text: "Beautiful Bird", url: "../images/rotator/bird.jpg" },
          { text: "Colorful Night", url: "../images/rotator/night.jpg" },

          { text: "Amazing Sculptures", url: "../images/rotator/sculpture.jpg" }
            ];
         var rotatorInstance = new ej.Rotator($("#sliderContent"), {
                slideWidth: "600px",
                frameSpace: "0px",
                displayItemsCount: "1",

                dataSource: website,
                orientation: ej.Orientation.Horizontal,
