Hello all. I the 'test.js' examples to run smoothly on Firefox, however it doesn't work on IE9 or chrome. I tried it with both my code and the downloaded code. The code produces no error but the data is not retrieved. Problem seemd to be at 'ajax.onreadystatechange = function() {...'. I placed an alert both before and after and the one before is the only one that pops up. Any ideas what I am doing wrong or what the problem is? Thank you in advance!
