AJAX POST n00b Problem

programming
1

Hello,
I am trying to write a simple AJAX program that alerts the parameters passed to the server.

JS:


http = new XMLHttpRequest();

http.onreadystatechange = function()
{
    if (http.readyState==4 && http.status==200)
    {
        alert(http.responseText);
    }
};

function post()
{
    http.open("POST", "http://url.com/get.php", true);
    http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
    http.send("number=100");
};

post();

get.php:


<?php
    echo $_POST['number'];
?>

When I run this program nothing shows up…
What am I doing wrong?

Thanks! :slight_smile:

Also if I add a tracer in the onreadystatechange fucntion the readyState goes from 2 to 4 but the status stays at 0.

And I just thought of it, but I am opening the html page from my local computer.
