[jquery] Submit a form using jQuery

You will have to use $("#formId").submit().

You would generally call this from within a function.

For example:

<input type='button' value='Submit form' onClick='submitDetailsForm()' />

<script language="javascript" type="text/javascript">
    function submitDetailsForm() {
       $("#formId").submit();
    }
</script>

You can get more information on this on the Jquery website.
