Hi...
I'm developing a simple script using AJAX and php to update a database...But the script is running fine on IE but not at all
on Firefox2.0.0.3....Please help me out
Here's my AJAX script
var xmlHttp
function showUser(str)
{
xmlHttp=GetXmlHttpObject()
if (xmlHttp==null)
{
alert ("Browser does not support HTTP Request")
return
}
var url="http://127.0.0.1/testminor/minor.php"
url=url+"?q="+str
url=url+"&sid="+Math.random()
xmlHttp.onreadystatechange=stateChanged
xmlHttp.open("GET",url,true)
xmlHttp.send(null)
}
function stateChanged()
{
if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete")
{
document.getElementById("txtHint").innerHTML=xmlHttp.responseText
}
}
function GetXmlHttpObject()
{
var xmlHttp=null;
try
{
// Firefox, Opera 8.0+, Safari
xmlHttp=new XMLHttpRequest();
}
catch (e)
{
//Internet Explorer
try
{
xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e)
{
xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
}
}
return xmlHttp;
}

Are you getting any specific errors in the firefox error console? I believe FF will reject XMLHTTP connections to pages that aren't on the same domain that the script runs from; I imagine that's amplified by the fact you're trying to connect to 127.0.0.1... Easiest way to get around this is to use relative/server absolute URLS in XMLHTTP opens..

I'm not getting any errors....
Just no output + no database update as I'm getting through IE
My html and php scripts are given below
These are just simple scripts....+
I wanna ask If firefox needs any plugin for AJAX
******************
<html>
<head>
<script src="clienthint1.js" language="javascript"></script>
</head>
<body>
<form name="form1">
<input type="text" name="ajaxtest">
<img height="30" width="50"src="Water lilies.jpg" onClick="showUser(document.form1.ajaxtest.value)">
</form>
<p>
<div id="txtHint"><b>User info will be listed here.</b></div>
</p>
</body>
</html>
*****************
And my php script is...
***********
<?php
$q=$_GET["q"];
$con = mysql_connect('localhost', 'root', 'anchal');
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("goonj", $con)
or die("Database not selected");
$sql="INSERT into users(name) values('$q')";
mysql_query($sql)
or die("Error");
echo "<table border='1'>
<tr>
<th>DATABASE UPDATED</th>
</tr>";
echo "</table>";
mysql_close($con);
?>

I ftp'd your files up to a live host. There, I arranged the files like so:
I had to change one line of your Javascript:
This meets the conditions of Firefox not allowing XMLHTTP open to 3rd party hosts; I could equally have used a full URL; but I'd have had to ensure I used the exact same domain to access the page.
The result is here: http://fusiongroups.net/temp
It works for the version of Firefox I have on Windows (1.0.7); try on yours, let me know if it says 'OK' when you click the button... If it does, the XMLHTTP open is working, and this means that there may still be a problem in that the domain you're using to access the page differs from the domain referenced in the XMLHTTP open() URL.
If the page at that link doesn't work (i.e. no OK when clicking the image), I'll swap operating system and have a look on the latest Firefox for you.

Thanks a lot for this...
I caught the problem
But as u know php scripts run under server only so as I'm test my scripts on xampp...The address 127.0.0.1 is mandatory for the scripts to run...unless I make directory structure like u have done...

Try and test on a 'real server'; or make sure that you always also access the page with the Javascript directly from 127.0.0.1. Providing that you do that; you should be able to omit the 127.0.0.1 from the Javascript code (which also removes the need to change the code when you do go live).
Xampp sets up a system whereby you can access any kind of page in a folder using a http url, so you should certainly be able to make a folder structure similar to the one I did.
