如何传递这个参数??
<form name=f method="post" action="act_right.asp">
<input type="text" name="PART_NAME">
<input name="PART_ID" type="hidden" id="PART_ID">
<input type="button" onclick="window.open('edit.asp?PART_ID+document.f.part_id.value+','win','width=400,height=300,state=no,toolbar=no')" value="编辑">
</form>
如何传送这个隐含的参数到edit页面??
