xAjax response

How to find status of response while using xajax.
I want to check in cases like when loading response, when loading completed.

In firebug we can just see the loading status.
But in code i want to check.
Like in normal ajax we check as if(respobj.status==200)... like this i want to check.
any idea on this?

[eluser]TheFuzzy0ne[/eluser]
Firebug does all of that, and much, much more! You can see the data sent, data received, headers sent and received, the status. The list is endless.

thanks for replying.
yes.. firebug will display all those things.

I am not telling about that status.
I am telling about XMLHttp object onreadystatechange Properties.

please go through this link http://www.w3schools.com/ajax/ajax_xmlhttprequest.asp.

here responseobject's ready state properties are tabulated(like '0' for request has not initialized , '1' for request has been set up) .

I want to know how we can test these status of response object in CI?

How can i test this below code using CI ?

xmlHttp.onreadystatechange=function()
{
if(xmlHttp.readyState==4)
{
// Get the data from the server's response
}
}


any ideas on this is very help full for me
