What is the difference between these jQuery ready functions?

Question

what is difference between

$(function(){

}); 

and

$(document).ready(function() { 

});

Answer 1

We have run into situations where IE9 does not run functions within $(function() {}); in the same manner or timing as $(document).ready(function(){});

The issue reared its head for us specifically in reading information out of a query string and processing and displaying that information on the screen, or using it to process a form. IE9 would process the information once it was cached with $(function(), and a user refreshed the page. But on first run, nothing worked right. However, once we switching from $(function(){}); to $(document).ready(), the issue was fixed. We changed NOTHING else.

I so look forward to the day I don't have to test for IE9 and lower.
