Screen.width
Returns the width of the screen.
Syntax
JavaScript
Copy Code
<var>lWidth</var> = window.screen.width
Example
JavaScript
Copy Code
// crude way to check that the screen is at 1024x768 if (window.screen.width > 1000) { // resolution is below 10 x 7 }
Notes
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%.
