Calling JavaScript function through another method

Question

There is a JavaScript function that is normally called through a form tag, using onsubmit.

In the code it looks like this:

<form method="post" name="form1" id="form1" onsubmit="return validate(this)">

If I were going to call the validate function through some other method, what variable would I pass it? I mean, the 'this' in the onsubmit call, what would I put there instead? Would it be the id of the form, so "form1"?

What do you mean by "some other method"? Also, can you give us more info on the validate function? — Theron Luhn

this refers to the element that the tag creates, that is, the form element. So you would call it with:

validate(document.getElementById('form1');

For more information on events, check out this introduction. The onsubmit attribute you're using is an inline event handler.

this in that context is the DOM element(the form)

So you should use it like this:

var form = document.getElementById('form1');
validate(form);

if not through a submit button, you can allways use form1.submit(); or to be more correct document.getElementById('form1').submit();

@Frank. What are you talking about?

I'm saying maybe he can just trigger it whenever he wants to call it.

@Frank. I don't know what he wants, maybe you should comment to him. Place your comment on the question.
