You can just add an input type = reset with an id = resetform like this
<html>
<form>
<input type = 'reset' id = 'resetform' value = 'reset'/>
<!--Other items in the form can be placed here-->
</form>
</html>
then with jquery you simply use the .click() function on the element with the id = resetform as follows
<script>
$('#resetform').click();
</script>
and the form resets Note: You can also hide the reset button with id = resetform using your css
<style>
#resetform
{
display:none;
}
</style>
