	The Arguments for windows.open
	You have a number of options for the third argument. When you define any of them, the remaining Boolean values (which can be true/false or yes/no or 1/0) are all set to false/no/0. Whichever you choose to use, all of your options go into the same quoted string, with commas between the values, and no spaces are allowed between them.
	height
	    Defines the height of the window in pixels. Percentage values don t work.
	width
	    Defines the width. Again, you ll have no joy with percentages.
	left
	    Supported by version 4 browsers and above, this sets how far removed the window appears from the left of the screen. In pixels.
	top
	    Partner to left, this pushes the window off the top of the screen.
	resizable
	    Set to true or false, this may allow the user to resize the window.
	scrollbars
	    Another Boolean value, this adds scrollbars to the new window. If your content may be longer then the dimensions you ve specified, make sure this is set to yes.
	toolbar
	    Specifies whether the basic back/forward toolbar should be visible. If there are links to follow in your new page, set this to yes.
	menubar
	    Specifies whether the main toolbar (File, Edit, ...) is shown.
	location
	    Specifies whether the location toolbar (address bar) is shown.
	status
	    Specifies whether the new window can have a status bar. Best set to yes.
	directories
	    Specifies whether the directories toolbar is shown (Links toolbar in IE).
	fullscreen
	    Internet Explorer-only Boolean attribute which may open the window in fullscreen. It s annoying don t use it.
	dependant
	    Netscape 4-only attribute which makes the popup dependant on the status of the main window. If the main window is closed, the popup closes with it.
	screenX & screenY
	    Old Netscape attributes for defining the window s position on the page. Use left and top in their place.
