jQuery AJAX request failing in IE

Question

The following AJAX call is failing in IE.

$.ajax({
    url:\"{{SITE_URL}}/content/twitter.json\",
    dataType:\"json\",
    error:function(xhr, status, erro         


        

Answer 1

What is the {{SITE_URL}} chunk giving is about. Try looking at the code in view source code of the browser. If the {{SITE _URL}} chunk has a trailing slash and that would make the request url:

http://modomain.com//content/twitter.json

Which could creep IE out?

Answer 2

For the caching problem why don't you simple use the cache: false parameter?

$.ajax({ 
    url: "yoururl",
    cache: false,
    ....

Answer 3

is this a copy/paste? the one thing that gets me all the time is leaving the last ',' in an object constructor. that is, most browsers JS accept:

o = { a:1, b:2, c:3, };

but IE chokes on this because the comma after the last item. change it to:

o = { a:1, b:2, c:3 };

and it works.

Answer 4

IE caches AJAX requests really aggressively (more so than Firefox, anyway). You need to set the Cache-Control headers in the response appropriately if this is not right for your site.

Answer 5

Fixed, I changed the content-type from application/json; charset=utf8 to just plain application/json.
I hate IE :)

Also to avoid IE super-caching try this:

var d = new Date();
$.ajax({
        url:"{{SITE_URL}}/content/twitter.json?_="+d.getTime(), 
...Snip...

That way each request is a new url for IE to get :D
