How do I validate / debug a javascript?

[madsgormlarsen]

When you write html or css then the validation proces is a good way of
finding errors. I get some syntax error / code: 0 errors in IE, how can
I figure out what the problem is. The thing is - it works - but it does
not look good when IE says the page is done with errors.

You can see the page and problem here -

Thanks for any help.

Double-click on the yellow warning sign in the left corner of your browser
and you will see a popup containing the last line number on which errors
where found.

Start at this line to scan for javascript delarations and you will notice
the following:

onmouseout="window.status = return true;"

When you replace this throughout the file with the following, it will work
fine:

onmouseout="window.status = ''; return true;"

mozilla firefox's javascript console is far more advanced, also consider
getting the javascript debugger extension from venkman for firefox

Also, in IE/Win, under Tools/Internet Options/Advanced
uncheck - Disable script debugging
check - Display a notification about every script error
