EXT Js Synchronous ajax request

rated 0 times [ 171] [ 1] / answers: 1 / hits: 46613 / 13 Years ago, fri, june 3, 2011, 12:00:00

How can I make synchronous ajax requests in EXT JS?

For example, given this code:

test1();

ajaxRequest(); //Ajax Request

test2();

The test2 function is executed without even finishing the execution of ajaxRequest(), which has an Ext.Ajax.request call .

How can I make text2() execute only after the ajaxRequest() function has been executed?

I understand that one way of doing it is to call the test2 function in a callback, but I have some dependencies and a lot of code that has to be executed after the ajax request, in a synchronous manner. Can you please help me with the best solution?

I needed something similar and after looking the source code of Ext.Ajax.request() and Ext.data.Connection, I found that they check for a async attribute, on the request() method, so, it's actually possible to make a synchronous request, like this:

var response = Ext.Ajax.request({

    async: false,

    url: 'service/url'

});

var items = Ext.decode(response.responseText);

It seems this async attribute is not documented, so... of course... be aware that it may change in future releases.
