Submitting a form can be accomplished with JavaScript by accessing the named form and then calling the submit method on it.
<form name="frmTest" action="somepage.html”" method="post">
First Name: <input type="text" name="FirstName">
<input type="button" onclick="document.frmTest.submit();" value="Submit Form">
</form>
The JavaScript occurs with the onclick attribute of the button input type. It uses the document object model to access the named form and calls the submit method on it.
