Append Form Value to URL Parameter

This site is best viewed in a modern browser with JavaScript enabled.

Hello All,

This page is a popup (http://www.example.com/PopUpPage.htm) launched by http://www.example.com/Parent-Page.asp
I want to close the popup and pass VARTOPASS to https://www.example.com/Not-The-Parent-Page.asp
Trying to figure out how to append DOCUMENT.FORM1.VARTOPASS.VALUE into URL parameter for onClick

Thank you,
Bob P.

Give this a try while replacing values with your own

<input onclick="window.open(document.URL, '_blank', 'location=yes,height=570,width=520,scrollbars=yes,status=yes');" type="submit" value="Submit">

If that doesn't work trying changing the input type to button.

Here's a quick example with some comments:
