Ajax/PHP

[COLOR=”Blue”]Ok so I am still trying to understand AJAX hopefully someone can help me with this.[COLOR=”Black”] I have (3) files ajax.js, index.php and classes.php .[/COLOR][/COLOR]

[B]On my index.php I call the object Menu() to display my menu links from the classes.php page. When I click on the link I want to use ajax to display the MapIt() function in the <div> area. But it still needs to go through the viewmaps process located on the classes.php page.[/B]

[B]What do I need to add to the viewIt() function in ajax.js to make this possible?[/B]

[B][U]ajax.js[/U][/B]

var xmlHttp;

function createXMLHttpRequest(){
if(window.ActiveXObject){
xmlHttp = new ActiveXObject(“Microsoft.XMLHTTP”);
}
else if(window.XMLHttpRequest){
xmlHttp = new XMLHttpRequest();
}
}

function loadingMessage(){
document.getElementById(“ajaxDiv”).innerHTML = “Loading please wait…”;
}

function clearResults(){
document.getElementById(“ajaxDiv”).innerHTML = “”;
}

function handleStateChange(){
if(xmlHttp.readyState == 4){
if(xmlHttp.status ==200){
document.getElementById(“ajaxDiv”).innerHTML = xmlHttp.responseText;

}
}

}

function viewIt(){
createXMLHttpRequest();
loadingMessage();
var url = “classes.php”;
xmlHttp.onreadystatechange = handleStateChange;
xmlHttp.open(“GET”, url + new Date().getTime(), true);
xmlHttp.send(null);
}
