Example
Using The Evaluator (Chapter 13 in the JavaScript Bible), see how the contains()
method responds to the object combinations in each of the following statements as
you enter them into the upper text box:
document.body.contains(document.all.myP)
document.all.myP.contains(document.all.item(“myEM”))
document.all.myEM.contains(document.all.myEM)
document.all.myEM.contains(document.all.myP)
Feel free to test other object combinations within this page.

Example
Listing 15-25 demonstrates the dispatchEvent() method as defined in the W3C
DOM Level 2. The behavior is identical to that of Listing 15-26, which demonstrates
the IE5.5 equivalent: fireEvent(). This example does not perform all intended
actions in the first release of NN6 because the browser does not fully implement the
document.createEvent() method. The example is designed to operate more completely
in a future version that supports event generation.
Listing 15-25: Using the dispatchEvent() Method
#mySPAN {font-style:italic}
// assemble a couple event object properties
elementObject.dispatchEvent()
