SYSK 309: How To Cancel a Web Service Request
AJAX makes asynchronous invocation of web service methods very easy. For example, the line below instantiates a web service proxy (MyService) and calls a method (MethodX):
var request = new MyService().MethodX(param1, param2, OnRequestComplete, OnError);
The question is: if you needed to cancel this request (e.g. it’s a resource intensive request and the user is navigating to another page, or a user made a request with different parameters but the previously submitted request has not been completed, etc.), how can you accomplish it?
As it turns out, it’s quite simple as well:
// Abort previously submitted request
request.get_executor().abort();
Special thanks to Steve Marx for the information.
