form action을 post방식으로 popup띄울수 있나

unction form_submit(){
chk = window.open('about:blank','네임값','width=300,height=400,scrollbars=yes');
if(chk != null){
폼네임.target='네임값';
폼네임.action='보낼문서'; //action은 요기에
폼네임.submit();
}
}
<form name=폼네임 method=post>
<input type=button onclick='form_submit();'>
</form>
