Chapter 2 ✦ Window and Frame Objects (Chapter 16)
msg = msg + “top name: “ + top.name + “”
msg = msg + “parent name: “ + parent.name + “”
msg = msg + “parent.document.title: “ + parent.document.title + “”
msg = msg + “window name: “ + window.name + “”
msg = msg + “self name: “ + self.name + “”
msg = msg + “self.document.title: “ + self.document.title
return msg
}
document.write(gatherWindowData())
In the two frames (Figure 2-4), the references to the window and self object
names return the name assigned to the frame by the frameset definition
(JustAKid1 for the left frame, JustAKid2 for the right frame). In other words, from
each frame’s point of view, the window object is its own frame. References to
self.document.title refer only to the document loaded into that window frame.
But references to the top and parent windows (which are one and the same in this
example) show that those object properties are shared between both frames.
