jeffman Posted May 15, 2010 Share Posted May 15, 2010 Look here. The second example comes closest to what you want. Link to comment Share on other sites More sharing options...
vmars316 Posted May 16, 2010 Author Share Posted May 16, 2010 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> Link to comment Share on other sites More sharing options...
Ingolme Posted May 16, 2010 Share Posted May 16, 2010 When called after the page loads, document.write() and document.writeln() automatically clear the page before writing. Link to comment Share on other sites More sharing options...
