/*
In order to use ajaxLoader, you need to do 2 things:
1. Define a state change handler that accepts an XMLHttpRequest object as
its first parameter -- this is the callback in which you actually get to do
stuff with the server response, e.g.:
function handleStateChange(req) {
if (req.readyState == 4 && req.status == 200) {
el = document.getElementById("output");
el.innerHTML = req.responseText;
}
}
2. Call ajaxLoader as the onload handler of your document's body tag,
passing in handleStateChange as the second param, e.g.:
Text retrieved from server will go here:
*/
function ajaxLoader(url, stateChangeHandler, arg1, arg2, arg3, arg4, arg5) {
if (document.getElementById) {
var x = (window.ActiveXObject) ? new ActiveXObject("Microsoft.XMLHTTP") : new XMLHttpRequest();
}
if (x) {
x.onreadystatechange = function() {
stateChangeHandler(x, arg1, arg2, arg3, arg4, arg5);
};
x.open("GET", url, true);
x.send(null);
}
}
