Ajax不会在IE 11中重新加载

Question

My code works flawlessly in chrome, however the AJAX doesn't reload in IE. Link to my code, suggestions? It loads at first but refuses to reload the page. I'm very stuck and I'd like to use only JavaScript if possible, I am open to use jQuery solution too.

Answer 1

By default, IE caches your AJAX calls. So, in order to make sure that a call is send, just add a time stamp. You need to update

xmlhttp.open("GET","chat.php",true);

to

xmlhttp.open("GET","chat.php?t=" + new Date().getTime(),true);
