View Full Version : My Broken AJAX auto reload DIV

Mar 10th, 2007, 01:17 AM
I spent a little while, I can't find why my script won't work.


That is the demo, it should (in the loading... section) show a blank area, since ajax.php is blank.

The message, if you hit enter, I don't think it should reset, and I don't think my sendRequest object is working proper. If anyone could take a look at the script I would really appreciate it.

function createRequestObject() {
var req;
// Firefox, Safari, Opera...
req = new XMLHttpRequest();
} else if(window.ActiveXObject) {
// Internet Explorer 5+
req = new ActiveXObject("Microsoft.XMLHTTP");
} else {
// There is an error creating the object,
// just as an old browser is being used.
alert('Problem creating the XMLHttpRequest object');
return req;


function handleDivTag(divtag)
var divtag;
return divtag;

// Make the XMLHttpRequest object
var http = createRequestObject();

// Create the Divtag Handler -- Mainly an IE 6 Fix
var divhandler = new handleDivTag(null);

function sendRequest(act,divtag) {
// Open PHP script for requests
http.open('get', 'ajax.php?act='+act);
http.onreadystatechange = handleResponse;
divhandler.divtag = divtag;


function handleResponse() {

if(http.readyState == 4 && http.status == 200){

// Text returned FROM the PHP script
var response = http.responseText;

if(response) {
// UPDATE ajaxTest content
document.getElementById(divhandler.divtag).innerHTML = response;



Thats AJAX.js.

Now here is chat.php.

<title>AJAX Example</title>
<script language="Javascript" type="text/javascript" src="/ajax.js"></script>
<script type="text/javascript">
function timingex( ){
setTimeout("sendRequest('chat', 'chat');",100);
// -->
<body onLoad="timingex( )">

<div id="chat" align="center">
Chat loading...

<br /><br />
<div align="center">Message: <form name="message" onsubmit="sendRequest(message.msg.value, 'chat'); message.msg.value = '';"><input type="text" name="msg" /></form></div>


I don't see what is wrong with it, please help.

The code in this post and the code on the link are very different. Did you figure out the problem and move on?

I used a new script. I couldn't figure out how that library worked.
