jquery ajax error json response

Question

i have jquery global error event set, like following:

 $("#message_alert").ajaxError(function(event, XMLHttpRequest, settings, thrownError){
    ajax_error(XMLHttpRequest);
 });

and ajax_error method gets the XMLHttpRequest parameter totally fine init. now the request which XMLHttpRequest gets, it also have json data from the backend in XMLHttpRequest.responseText

now i want to know, how can i parse this json data, i tried doing

eval("var request = "+XMLHttpRequest.responseText);

which for some reason was working fine, but dose not work anymore and i know for sure that data is getting back to ajax response. maybe something im doing wrong.. well firebug shows following error from it, i dont know what im doing wrong

Error:

missing ; before statement

Answer 1

Have you tried -

eval("var request = XMLHttpRequest.responseText");

That should fix the error you are getting.
