Look here. The second example comes closest to what you want.
Ah, yes, good aim.Which led me to : http://www.w3schools.com/js/js_ex_dom.asp http://www.w3schools.com/js/js_examples.asp But I am not asking 'how to open a window'. I am saying 'given the code above', (see line 30.) He uses no OPEN , and still he manages to open a window,or at least clear orig window, then writeln to print a receipt. Anyways, Thanks for the link...vmars316 almost forgot, I combine both openWindows into one, in case there are other newbies, like me reading here:<html><!-- http://www.w3schools.com/jsref/met_win_open.asp --><head><script type="text/javascript">function openWin(){myWindow=window.open('','','width=200,height=100');myWindow.document.write("<p>This is 'myWindow'</p>");myWindow.focus();}function open_win() {window.open("http://www.w3schools.com");}</script></head><body><form><input type="button" value="Open little window" onclick="openWin()" /> <input type=button value="Open URL Window" onclick="open_win()" /></form></body></html> Edited by vmars316
