Submiting a form using javascript

[bizt]

Hi,

First let me point out I have googled this and also must have done
this operation a dozen times (altho a few years ago) but for some
reason I cant get a form to submit using javascript .. Ive tried both
FF and IE. All the pages that I look at all say the same way which is
the way Im sure Ive done it before:


My code is:

(javascript function)

function DeleteImages (oForm) {
alert('submitting form') // this works ...
oForm.submit() // this doesnt!!
}

(html button)

<input type="button" name="submit" value="Delete Selected"
onclick="DeleteImages(this.form);" />


Maybe just a sanity check is needed but I cant see what the problem
is. Where am I going wrong? I know that the function is being called
because the alert message is executing but the form isnt submitting.

Cheers

Browsers make named controls available as properties of the DOM form
object. Giving any control a name of 'submit' shadows the form's
submit method, so form.submit() is equivalent to
form.elements['submit']().

There is rarely any need to name a submit button, remove the name (or
change it to something other than 'submit') and life will return to
normal...

There is. Frequently. When your server-side script wants to know,
whether you hit "cancel" or "delete" or "save"...

So? Can't you name it 'delete', 'cancel' and 'save'?

I guess you mean where a form has multiple submit buttons to indicate
which of a number of actions to take when the form is submitted - the
name can be used to determine which button was used to submit it.

That's certainly one case where naming the button is useful, athough
the same functionality can be provided using a single submit button
and say checkboxes or radio buttons to indicate the action to take.

Agreed, but I wouldn't call that good usability.

When have you last seen such a form? (It makes sense for multiple
entries, though.)

Sure. But you *named* it.
