could anyone help me out on this one.

 

i'm not proficient in using ajax...

 

 

it's not working on my part.

I highly recommend that you use a javascript library for this. It would only take two or three lines of code to do an ajax request, compared to the hundred or so lines of code you have there.

 

And the big benefit is, the libraries code works from the git allowing you to move on to the good stuff

 

I use and recommend Yahoo YUI. jQuery is another great library as well.

Firstly, a question to you. What are you trying to do with that code? You are using POST which is not required most of the time. Using GET method is much more simple.

 

Where and how did you call the function makePOSTRequest2?

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script>
<script type="text/javascript">
  function makePOSTRequest2(url, parameters) {
    $.post(url,parameters,function(response){
      alert(response);
    });
  }
</script>
