带有jQuery 1.5.1的跨域ajax

Question

I have used ajax with jquery 1.4.2 on my domain, but I need to get a page from another domain. The following code works with jquery 1.4.2 but I want to use 1.5.1:

$.ajax({
    type: "POST",
    dataType: "html",
    crossDomain: true,
    url: "http://www.domain.com/page.aspx",
    error: function() {
        alert("error");
    },
    success: function(msg){
        alert(msg );
    }
});

For some reason I get an error, but when I change to jquery 1.4.2 it works.

what am I doing wrong?

Answer 1

You need to add the following header in the response (need control over both domains)

Header set Access-Control-Allow-Origin "http://your-domain.com"

In your Javascript code you need to add

jQuery.support.cors = true;

It works at least with 1.6.2, but only in Firefox (and Chorme I think), IExplorer don't support CORS standard...
