[SOLVED] Single Instance Multiple Request

[xenophobia]

I had a single instance of XHR object.

 

Everytime I clicked a button, this XHR object will send the request to server to get some info.

 

What I want is, whenever I clicked, if there is some unfinished transaction in the previous one will be aborted and start with the new one. How am I going to do that?

 

Better picture:

// Get the xmlHttpRequest object.
var xhr = init_object();

if(isLoading) {
   xhr.abort();
}

xhr.open('new.php', ...blar blar...);
xhr.send(null);

Maybe I should ask in this way:

 

Say currently, request A is made to server.

While it is loading, a user click on another button, request B is made.

 

So I want to abort the request A and made a new request to server (request B).

 

How do I do that??

Is actually not the ajax problem. =[ I've found that is actually my server's side scripting problem.

 

Problem solved.
