I just update jQuery RIA framework from jQuery1.3.2 to 1.4.2, connot call callback function.

Demo url: ​http://dwz.duqn.com/

jQuery.ajax({

type:"POST", url:url, data:{}, success:callback, dataType:"json"

});

I was unable to read the test page to see how to submit an ajax request. The most likely cause of a problem with json from 1.3 to 1.4 is that the site is not producing valid json:

VALID: {"test": "string"} INVALID: { test: "string"} INVALID: { 'test': "string"} INVALID: { "test"": 'string'}

jQuery 1.4.2 Ajax bug

[zhanghuihua]

jQuery.post( url, [ data ], [ success(data, textStatus, XMLHttpRequest) ], [ dataType ] )

Connot call success callback function, when dataType is "json" the jQuery version is 1.4.2.

Please download the attachment "ajax-bug.zip" and open "json-test.html" on IE or firefox.

The problem with your original example is that you were attempting to parse/load malformed JSON structures using $.post. If you take a look at your original file (ajaxDone.html) you will see this.

I've uploaded a correctly formed JSON example here, being loaded by your original code, save for the output being different due to the change in JSON file.

As you can see in FireFox, this is working fine using jQuery 1.4.2.

Closing this ticket as it is not a bug.
