By default popups cannot be resized by the user. This is usually not a problem... most popups just contain small notes or ads. If your popup contains a lot of information, however, it's a nice touch to let the user resize the window to something more convenient. Set the popup to resizable by setting the
command. For example, this command in the
opens a resizable popup:
window.open(href, windowname, 'width=400,height=150,resizable=yes,scrollbars=yes');
which gives us this popup.
