[jQuery] Response Status Codes

[Anjanesh]

Hi

All this time I was using AJAX natively. But now Im getting the hang
of jQuery.

I normally want to check if Im getting a 200, 404, 500 etc response
status on success
[code]
var xhr = NewXMLHttpRequest();

xhr.onreadystatechange = xhrChange;

function xhrChange()
 {
        switch (xhr.readyState)
         {
                case 1: // Open
                break;
                case 2: // Send
                break;
                case 3: // Receiving
                break;
                case 4: // Loaded
                switch (xhr.status)
                 {
                        case 200: // OK
                        break;
                        case 404: // Not Found
                        break;
                        case 500: // Internal Server Error
                        break;
                 }
                break;
         }
 }
[/code]
Looking at the docs (http://docs.jquery.com/Ajax/jQuery.ajax#options)
I see that :success and :complete can stand for case 4 and case 200
respectively.

But how do I get to 'know' the other status codes ?

Thanks
