our website opens a NEW registration window [target="_blank"], register1.asp which submits form data to register2.asp "write to database" and "thank you for registering" page, by way of js form validation function - >>>i need to cause register2.asp to open without the ability to hit the BACK button [ie, no menu bar or address bar].<<< reason: people are registering online, then hitting BACK and hitting submit AGAIN, causing multiple database entries. <argh>

more simply: website opens new registration page, register1.asp. user submits info which gets form validated before sending to register2.asp. register2.asp need NO menu.

some code:
<form name="form1" method="POST" action="https://secureServerName/domain/register2.asp" onSubmit="return submitIt(this)">

this first passes form data to "submitIt()" function with "this" [this is the form data]. if everything passes TRUE, then it passes control to register2.asp. I need this register2.asp to NOT have a menubar.

I hope this does not sound too messy, and any ideas anyone?? thanks in advance for your time.

Ok...here is what you need to do.

function submitIt(myForm) {
var w = window.open('about:blank','Popup_Window','toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbar=yes,resizable=yes,copyhistory=yes,width=200,height=200,left=10,top=10');
myForm.target = 'Popup_Window';
return true;

<form name="form1" method="POST" action="https://secureServerName/domain/register2.asp" onSubmit="return submitIt(this)">
Form content

Hopefully it should work for you.

thx, but i get error saying zero length field not allowed[database error] - doesn't seem to send the form data via the var w. wishing now there were some parameters when sending data via method="post", that would define the target window with no menu. my code with your suggestions - [form name is "form1"]:

var w = window.open('https://servername.ntsecure.net/domain/filename.asp','registerSendInfo','toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbar=yes,resizable=yes,copyhistory=yes,width=200,height=200,left=10,top=10');
document.form1.target = 'registerSendInfo';
return true;
}//END submitIt

thx, though - i am tempted but not looking forward to creating code to check and reject if form data entered already exists in the database.
