<script> 
function go() { 
 var ifm=document.createElement('IFRAME');
 with (ifm) {
  name='mashup';
  style.display='none';
 }
 document.body.appendChild(ifm);
 var ifm2=ifm.cloneNode(true);
 ifm2.name='mashup2';
 document.body.appendChild(ifm2);
 
 var frm = document.forms['calendar'];
 
 frm.target='mashup';
 frm.action='http://www.aaa.com/2/test1.php';
 frm.submit();
 
 setTimeout('go2()', 10);
 
 return false;
}
 
function go2() {
 var frm = document.forms['calendar'];
 
 frm.target='mashup2';
 frm.action='http://www.aaa.com/2/test2.php';
 frm.submit();
} 
</script> 
 
<form name="calendar" method="post" target="mashup" enctype="multipart/form-data" onSubmit="return go()">
<input type="text" name="userid">
