Call function onSubmit

Hi,

Basically I have 2 frames called middle and bottom the middle frame holds a form and the bottom frame holds a javascript form submit buttom.

Code: 
<a href="javascript:parent.middle.document.faultform.submit()">Submit</a>

If I click on this it submits the form fine, however there is a javascript error checking procedure called validform() written into the middle page that is normally called when the submit button is on the same frame:

Code: 
<form name=faultform onSubmit="return validform();" action="next_page.asp" method="post">

However whrn the js submit button is clicked in the bottom frame the validate() function isn't called, it just submits.

So my question is how can I keep the submit button in the seperate frame but call the function in the other frame as the for is submitted?

Calling the submit method of a form always bypasses its "onsubmit" event handler. Suggest instead doing something like this:

Code: 
<a href="javascript:submitForm();">Submit</a>

and have this code in your lower frame's head section:

Code: 
<script type="text/javascript">
<!--
   function submitForm() {
      var formPage = parent.middle;
      if (formPage.validForm()) formPage.document.faultform.submit();
   }
//-->
</script>

I'm not aware of the circumstances surrounding your decision to put the submit button in a different frame (you didn't give much away), but if it's not too important to do it your way, spare a thought for those without JS and/or frames capable browsers and have a "normal" submit button which doesn't need JS to function.

Hope this helps,
Dan

I have tried that, but it doesnt seem to work. I can get half of it done, getting the form validation to run from the following code...
Code: 
function submitform(){
parent.middle.document.faultform.onsubmit();
}

but then I also need the form to submit if no errors are found as I have unsussefully tried below
Code: 
function submitform(){
parent.middle.document.faultform.onsubmit();
if (parent.middle.document.faultform err ==0){
parent.middle.document.faultform.submit()
else if(err==0){ return false;} 
}
}

the full validation code I obtained form a tutorial site is below, I think I should be testing for:

if (err==0){ return false;}

Any ideas?

Code: 
<script type="text/javascript" language="JavaScript" >

Change your submitForm() function to return false if it encounters an error and true otherwise.

Then update your function as such:

Code: 
function submitform(){
 [b]if([/b]parent.middle.document.faultform.onsubmit()[b])[/b]
  parent.middle.document.faultform.submit()
}

That should do it (I hope!).

Really? Try this test harness out:

Code: 
<html>
<head></head>
<body>
	<form onsubmit="alert('Submitting!');">
		<input type="button" onclick="this.form.submit();" value="Fake submit">
		<input type="submit" value="Real submit">
	</form>
</body>
</html>

As you can see, calling the "submit" event totally bypasses the onsubmit handler.

Sorry - I should have said "submit method", not "submit event".

So calling the submit method bypasses the onsubmit event.

If I call the onsubmit() and add the following to the end of the procedure, why doesn't this work?

Code: 
if (err==0){return false;} 
else {return true;}
}

Hope someone can help?

Thanks
