Chapter 13. Windows and Frames > Window Control Methods

13.8. Window Control Methods

The Window object defines several methods that allow high-level control of the window itself. The following sections explore how these methods allow us to open and close windows, control window position and size, request and relinquish keyboard focus, and scroll the contents of a window. We conclude with an example that demonstrates several of these features.

13.8.1. Opening Windows

You can open a new web browser window with the open( ) method of the Window object. This method takes four optional arguments and returns a Window object that represents the newly opened window. The first argument to open( ) is the URL of the document to display in the new window. If this argument is omitted (or is null or the empty string), the window will be empty.
