JQuery AJAX fails with IE

Question

I have a function for doing ajax calls (line numbers supplied):

9 function doAjax(url, args){ 10 var retVal; 11 retVal = $.ajax({ 12 type: "GET", 13 url: url, 14 data: args, 15 async: false, 16 }).responseText; 17 if(retVal==null || retVal=="")retval=99; 18 return retVal; 19 }

When I use IE8, I get an error stating:

User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; GTB7.1; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; MDDR; .NET4.0C; .NET4.0E) Timestamp: Mon, 25 Jul 2011 17:45:36 UTC

Message: Expected identifier, string or number

Line: 17

Char: 21

Code: 0

URI: local host web server

This script works perfectly fine with FireFox. Being a novice, I am at a loss as to why this is generating an error. Can anyone point me in the right direction?

Does anyone else laugh to themselves a little when they hear AJAX refer to a function which is not asynchronous, and does not use xml? — aepheus

Try taking out the comma after

async: false

Putting a comma after the last member of an object can cause IE to freak out.

Thanks for the quick feedback. That did indeed resolve my issue. Many times in life it is the very smallest of things that cause the most problems.
