Add QueryString Values to Javascript Reload Question

Hi, I have a form that automatically reloads when drop downs are selected. I wanted to know if it’s possible to add QuesryString values on refresh.

Thanks

<script language=”javascript”>
<!–
function reload(){window.location.reload();}

function dept_onchange(frmSelect) {
frmSelect.submit();
};

//–>

</script>

Also in #JavaScript _↴
