form help

[matt]

I have a form with a dropdown menu and I want to make sure that people
have clicked on something. I have a NA one at the bottom but I want an
error to popup if they dont move it from its default value

Thanks
Matt

Put the default at the top, then check for selectedIndex being greater
than 0.

You cannot make it sure. Client-side scripting can be disabled
or not even supported. Server-side checking is required anyway,
but you can reduce round trips with client-side checking.

?
but I want an error to popup if they dont move it from its
default value

function checkMe(oForm)
/**
* @param oForm
* Reference to the HTMLFormElement object to be checked.
* @returns
* <code>true</code> if validation is passed,
* <code>false</code> otherwise (and thus canceling the event).
*/
{
if (/* any form control has its default value */)
{
alert(...);
// ...
return false;
}
return true;
}

<form ... onsubmit="return checkMe(this)" ...>
...
</form>
