Submit() and onSubmit()

[Christopher Benson-Manica]

Why the heck doesn't document.aForm.submit() invoke aForm's onSubmit event
handler?

Because it doesn't.

If you want it to, use Opera 7.0 or 7.1 which had a bug that caused that
behaviour (it's been fixed in 7.21).

The obviously solution is to call the validator code before calling submit():

<a href="noJS.html" onclick="
var f=document.forms['aForm'];
if (validate(f)) f.submit();
">Submit</a>

This would have the same effect as:

<form ... onsubmit="return validate(this);">
<input type="submit" ... />
</form>

I think I was misunderstood - I *know* it doesn't, I was curious about the
rationale.

I suppose, although I still wish my original plan were possible.

The event does not fire here because the submit is initiated by the
author/programmer, not by the user. But if you need to call the event
handler explicitely, use

document.forms['aForm'].onsubmit();

in IE 6.0 and Mozilla/5.0, since it is implemented as an anonymous
function there. (Note the use of the standards-compliant `forms' collection.)
