Screen.width

Returns the width of the screen.

SyntaxEdit

lWidth = window.screen.width

ExampleEdit

// crude way to check that the screen is at 1024x768
if (window.screen.width > 1000) {
  // resolution is below 10 x 7
}

NotesEdit

Note that not all of the width given by this property may be available to the window itself. When other widgets occupy space that cannot be used by the window object, there is a difference in window.screen.width and window.screen.availWidth. See also window.screen.height.

Internet Explorer will take into account the zoom setting when reporting the screen width. It will only return the real width of the screen if the zoom is set to 100%.
