Maximized browser window using JavaScript

I will use window.open() to maximized the web page. First look at the syntax of this method. window.open(URL,name,specs,replace). To view the parameters please click here.

window.open(URL, "MyTab", "width=" + screen.availWidth + ",height=" + screen.availHeight)

screen.availWidth will return the maximum width of the display screen.
screen.availHeight will return the maximum height of the display screen.
