How to show fullscreen popup window in javascript?

Question

Is there a way to make a popup window maximised as soon as it is opened? If not that, at least make it screen-sized? This:

window.open(src, 'newWin', 'fullscreen="yes"') 

apparently only worked for old version of IE.

Answer 1

Use screen.availWidth and screen.availHeight to calculate a suitable size for the height and width parameters in window.open()

Although this is likely to be close, it will not be maximised, nor accurate for everyone, especially if all the toolbars are shown.

Answer 2

What about this:

var popup = window.open(URL); if (popup == null)    alert('Please change your popup settings'); else  {   popup.moveTo(0, 0);   popup.resizeTo(screen.width, screen.height); }
