document is undefined

[fifo85]

Hi,
I wonder if anyone can help me out here I am writing a web application in asp javascript.
the problem is that when i enter the line shown below

document.forms["GroupForm"].elements["GroupDD"].disabled='true';

i keep getting the following error
Error Type:
Microsoft JScript runtime (0x800A1391)
'document' is undefined
/DCASuppliersDatabase/CategoryListing.Mod.asp, line 154

Why is this? I thought document is a valid keyword that points to the current page.

Regards

That's usually the result of a corrupted file cache. Try the solution here:

Thanks for the response,

but the error i get occurs when i run my application on the web browser

the link that you sent does not cover runtime errors,
any hints?

Sounds like you're mixing up client-side and server-side code. They are
completely independant. You can't put client-side code inside your dynamic
<%%> blocks. ie. this won't work:

<%
document.forms["GroupForm"].elements["GroupDD"].disabled='true';
%>

will need to be on the client instead. ie

<script>
document.forms["GroupForm"].elements["GroupDD"].disabled='true';
</script>

Thanks so much Julian,

That did the trick, I thought all the code gets excecuted on the server side on asp. I'm new do web application
development, well this is my first one, I could really do with an insight into how the whole system (client side/server side) works.
you know any useful sights where i can get a good grounding into web application development and javascript/asp.

Thanks Again,

Fifo
