refresh Method

The refresh method reloads the DataView, and provides an object to which you can bind event handlers such as the .then() method. See deferred.then() in the jQuery API documentation for more information.

Syntax

Javascript (Usage)
Javascript (Specification)

var instance = new wijmo.data.AjaxDataView();
var value; // Type: any
value = instance.refresh();

function refresh() : any;

Return Value

Returns a deferred promise object. (See deferred.promise() in the jQuery API documentation for more information.)

Example

The deferred object sets the state to success or fail. So we can define the success callback and fail callback in the .then() method.

Javascript

ajaxDataView.refresh().then(
          function(){
              alert("Refresh Success!");
          },
           function(){
              alert("Refresh Fail!");
          },
     );
