In this last lesson we will talk briefly about the most top level object in JavaScript hierarchy which of course is the window Object. The section concerning pop-up windows is not complete yet but I do provied a link to a page on my JavaScript Corral Site where you can learn how to do Pop-up Windows. I also plan of doing a wrap up on this tutorial either in this lesson or as a Lesson 15.
window Object
Listed below are the properties and methods of the window object. Note that an indication as to whether the property is settable or not is provided. See the note at the end of the Properties table for an explanation. An indication as to which browsers the properties and methods work on is also given. If left blank, then that particular property or method should work on all browsers that support JavaScript.
