86 JavaScript Examples Bible: The Essential Companion to JavaScript Bible
Notice that although you can no longer adjust the font size from the lower text
box, the most recent value assigned to it still sticks to the element. To prove it,
enter the following statement in the topmost text box to see the current value:
myP.style.fontSize
removeNode(removeChildrenFlag)
NN2 NN3 NN4 NN6 IE3/J1 IE3/J2 IE4 IE5 IE5.5
Compatibility ✓ ✓
Example
Examine Listing 15-21 for the appendChild() method to understand the difference
between removeChild() and removeNode(). In the restore() function, you
can replace this statement
mainObj.removeChild(oneChild)
in IE5+ with
oneChild.removeNode(true)
The difference is subtle, but it is important to understand. See Listing 15-31 later
in this chapter for another example of the removeNode() method.
replaceAdjacentText(“location”, “text”)

Compatibility ✓ ✓
Example
Use The Evaluator (Chapter 13 in the JavaScript Bible) to experiment with the
replaceAdjacentText() method. Enter each of the following statements into the
top text box and watch the results in the myP element (and its nested myEM element)
below the solid rule:
document.all.myEM.replaceAdjacentText(“afterBegin”, “twenty”)
Notice that the myEM element’s new text picks up the behavior of the element. In
the meantime, the replaced text (all) is returned by the method and displayed in
the Results box.
document.all.myEM.replaceAdjacentText(“beforeBegin”, “We need “)
elementObject.replaceAdjacentText()
