Question

Prototype's Ajax.Request and Internet Explorer 8

Answer 1

+1 A:

Are you doing this in a web site or using a file? I was able to get your code working in a web site in Visual Studio, but when I tried it from a file I got an "Access Denied" error. I suspect that it is not able to do an Ajax request to a file in the local file system due to security restrictions in IE8.

Here's the exact code I used in my Default.aspx page to load the page.htm file. Note that I changed the method -- since it's not a form -- and I added callbacks for failure and exceptions. The exception callback was what got triggered for me with a local file. As I said, it works fine when accessing a page in the same web site.

<script type="text/javascript">
    document.observe( 'dom:loaded', function() {
     new Ajax.Request("page.htm", {
      method: 'get',
      onSuccess: function(response) {
       alert(response.responseText);
      },
      onFailure: function(response) {
       alert(response);
      },
      onException: function(request,error) {
       alert(error.message);
      }
     }); 
    });
</script>

Answer 2

A:

Just an aside to the existing answer, and just wanted to mention, that IE8 does some crazy caching when you use 'get' in your Ajax calls. My web application worked fine in FF, but in IE8, some of the ajax calls were never made. I changed the method: from 'get' to 'post' and all was well.

method: 'post'

Also, to further ensure no funny business in IE8 with session variables, put the following meta tags in the head of your html pages.

<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="-1">
