Ajax Error Help

Timmymna · 03-10-2008, 12:14 AM

I have just started learning about Ajax today and was working through some examples online. I have come across a very simple one that I just can't get to work

The tutorial I have copied the code from.

When I choose from the drop down box nothing happens I get an error icon in the corner. It states:

Code:

Line: 9
Char: 1
Error: Object Expected
Code: 0

The code I used is:

PHP Code:


			
<html>

<head>

<script src="selectuser.js"></script>

</head>

<body><form> 

Select a User:

<select name="users" onchange="showUser(this.value)"> 

<option value="1">Peter Griffin</option>

<option value="2">Lois Griffin</option>

<option value="3">Glenn Quagmire</option>

<option value="4">Joseph Swanson</option>

</select>

</form><p>

<div id="txtHint"><b>User info will be listed here.</b></div>

</p></body>

</html>

If anyone can point me in the right direction, thanks

Have you saved selectuser.js in the same directory?

Thanks for your reply, yeah selectuser.js is in the same directory.
I have also tried copying the contents of selectuser and putting it in the html file but I still get the same error.

Could it be something to do with the server side of things as I'm using one I've setup and may have missed something trivial

Well, the firefox's addon firebug is a best friend to find out the cause of such errors. BTW, I use Sajax toolkit, very easy to handle.

Installed firebug which gave me an error that led me to a couple of websites and solved the problem

I had to change:

PHP Code:


			
var xmlHttpfunction showUser(str)

{

to:

PHP Code:


			
var xmlHttp



function showUser(str)

{

Thanks for the help abduraooft
