Question

I have to use a user control form

In that form, there is a Submit button.

That button is html button.

That button has lots of validation functions for the other controls.

Now I want to add another function of my own into that button.

Now I faced my problem. I dunno the ID of that button.

When I view source I find no ID or Name.

But I can use

<script type="text/javascript">            
     $("input[type=submit]").click(function () { return validateCaptcha(); })
</script>

To add my function.

If I do that, only my function would run and the other original validation functions are not running anymore.

I want to append my function at the end of its validation functions.

I found this..

JavaScript: Adding an onClick handler without overwriting the existing one from another question

But that one find the controls by tagname. If I find it by tagname there would be lots of input tags.

Is there any other way to combine the 2 answers that I found?

Answer 1

If you know the name or the ID of the form you are working on you could do

$("#formname").submit(function(){return validateCaptcha(); });

or

$("form[name=form_name]").submit(function(){return validateCaptcha();});

Witout knowing the ID of the submit button or the form (or the name of either) it would be difficult to validate; you need some sort of identifier.
