jQuery.isWindow()

Categories: Deprecated > Deprecated 3.3 | Removed | Utilities

jQuery.isWindow( obj )Returns: booleanversion deprecated: 3.3, removed: 4.0

Description: Determine whether the argument is a window.

Note: This API has been deprecated in jQuery 3.3; if you need this function, reimplement it by yourself:

function isWindow( obj ) { return obj != null && obj === obj.window; }

This is used in a number of places in jQuery to determine if we're operating against a browser window (such as the current window or an iframe).
