I'm trying to intercept the submission of a form in order to change the value of my keywords label.

I have the following code:

<HTML>
<FORM name="searchForm" method="get" action="tmp.html" >
<input type="label" name="keywords" />
<input type="button" name="submit" value="submit" onclick="formIntercept();"/>
</FORM>
<SCRIPT language="JavaScript">
document.searchForm.keywords.focus();
function formIntercept( ) {
    var f = document.forms['searchForm'];
    f.keywords.value = 'boo';
    f.submit();
};
</SCRIPT>
</HTML>

When I run this in chrome and click the submit button the keywords label changes to boo, but the javascript console says:

 Uncaught TypeError: Property 'submit' of object <#an HtmlFormElement> is not a function.

How can I submit the form with the manipulated keywords?
