Abort the AJAX Request (dojo)

gaya3 · #1 September 5th, 2008, 05:24 AM

Hi All,

I am using dojo.xhrPost to send an ajax request.I would like to know if there is a way that when another javascipt event is executed before that request was finished, can I abort that request.
How can i abort the request? Thanks in Advance...

why do you want to abort the ajax request?

nevertheless, you only need a second condition (besides request.status == 200) that the second javascript invokes.

I don't think you can abort ajax request. You can ignore handle the ajax response. for example:

Expand|Select|Wrap|Line Numbers

 
var ajaxHandler = function( returnData )

{

    if ( flag == false )

    {

        //do something with the returnData

    }

}
 
var otherEventHandler = function()

{

    flag = true;    //When another event is executed,set flag to true.

}
 
var flag = false;    //false when handle ajax response

var ajax = new Ajax(...);    //initialize ajax object

ajax.onreadystatechange = ajaxHandler;    //set ajax handler

ajax.post(...);

hope it helps

in case you have a reference to the requestobject then you may use its abort()-method ... have a look at it here

kind regards

ISSUE IN ABORTING XHRPOST

We are using Dojo 1.1 to display data in grid format.

When the display button is clicked grid will be displayed and ajax calls( dojo xhrpost) will be initiated to fetch data. AJAX calls will update the session with fetched data. AJAX calls will be initiated until all the data is fetched.( Complete data set cannot be fetched at a stretch, as the data set is large. Hence we use AJAX calls to update the session)

If the display button is clicked again, the ongoing AJAX cals should be aborted and new AJAX calls should be triggered for the new serach criteria.

We are unable to abort the ongoing AJAX calls. The previous AJAX calls and the new AJAX calls are updating the data in session leading to incorrect data.

Please provide us some suggestion

Thanks

Check post #4 by gits. If that doesn't help, check the API reference on the dojo website.

How can we get the reference of XMLHTTPRequest in DOJO

acoder · #10 December 9th, 2008, 09:56 AM

This link might help. Use the cancel() method. If that doesn't work, you can use the abort() method on the args object passed to the xhrPost function.
