Chapter 2 ✦ Window and Frame Objects (Chapter 16)
In the toggleFrameScroll() function, the if condition checks whether the
property is set to something other than no. This allows the condition to evaluate to
true if the property is set to either auto (the first time) or yes (as set by the function).
Note that the scrollbars don’t disappear from the frames in IE5.5 or NN6.
Listing 16-45: Controlling the FRAME.scrolling Property
frame.scrolling Property
function toggleFrameScroll(frameID) {
// IE5 & NN6 version
var theFrame = document.getElementById(frameID)
// IE4+ version
// var theFrame = document.all[frameID]
if (theFrame.scrolling != “no”) {
theFrame.scrolling = “no”
} else {
theFrame.scrolling = “yes”
}
}
// generate content for each frame
function fillFrame(frameID) {
var page = “”
page += “This frame has the ID of:” + frameID + “.”
page += “”
return page
