Using Node Properties
As an example of utilizing these properties, you can examine one of the paragraph () nodes from
your previous example. You will add some further script code to the previous example, as shown in the
following code block:
var node = paragraph;
var msg = “Node Name: “ + node.nodeName;
msg += “\nNode Type: “ + node.nodeType;
msg += “\nNode Value: “ + node.nodeValue;
msg += “\nNode Child Name: “ + node.firstChild.nodeName;
msg += “\nNode Child Type: “ + node.firstChild.nodeType;
msg += “\nNode Child Value: “ + node.firstChild.nodeValue;
alert(msg);
This will produce the dialog box shown in Figure 3-6.
