PHP AJAX CHAT, Bug fixes - including weird mozilla bug ...

When I released PHP AJAX chat I knew that there was a problem with a few of the build of Firefox that didn’t like having SetTimeouts() outside of functions and requestobjects opening without full parameters. Well I have now fixed that and here is the patch. To install the patch do the following.

   1. Open up index.php oh php ajax chat archive
   2. find where this line is <script type=”text/javascript”> in mine it’s around line 33 and also find the end </script> which is around line 99.
   3. Hilight this area and replace it with the following code

function sndReq(doit) {
var xmlhttp;
/*@cc_on
@if (@_jscript_version >= 5)
try {
xmlhttp = new ActiveXObject(”Msxml2.XMLHTTP”);
} catch (e) {
try {
xmlhttp = new ActiveXObject(”Microsoft.XMLHTTP”);
} catch (E) {
xmlhttp = false;
}
}
@else
xmlhttp = false;
@end @*/
if (!xmlhttp && typeof XMLHttpRequest != ‘undefined’) {
try {
xmlhttp = new XMLHttpRequest();
} catch (e) {
xmlhttp = false;
}
}
httpr = xmlhttp;

if(doit){
chatsend = document.getElementById(”textbox”).value;
guyname = document.getElementById(”guyname”).value;
parameters = “nick=”+encodeURI(guyname)+”&textbox=”+encodeURI(chatsend);
httpr.onreadystatechange = handleResponse;
httpr.open(”POST”, “<?php echo $url;?>rpc.php”,true);
httpr.setRequestHeader(”Content-type”, “application/x-www-form-urlencoded”);
httpr.setRequestHeader(”Content-length”, parameters.length);
httpr.send(parameters);
document.getElementById(’textbox’).value = ”;
}else{
httpr.onreadystatechange = handleResponse;
httpr.open(”GET”,”<?php echo $url;?>rpc.php”,true);
httpr.send(null);
}
setTimeout(”sndReq(false)”,2000);
}

function handleResponse() {
if(httpr && httpr.readyState == 4){
var response = httpr.responseText;
document.getElementById(”chatbox”).innerHTML = response;
}
}
function formsubmit(e){
characterCode = null;
if(e && e.which){ //if which property of event object is supported (NN4)
e = e
characterCode = e.which //character code is contained in NN4’s which property
}
else{
e = event
characterCode = e.keyCode //character code is contained in IE’s keyCode property
}
if(characterCode == 13){
sndReq(true);
}
}
sndReq(false);
