A simple Command example 141
The next part of the return statement (&& (theSelNode.nodeType == Node.TEXT_NODE)
checks to see if the selected node type is text. If so, the
canAcceptCommand() function
returns the value
true. If the node type is not text, the test continues to see if the node has
children (
|| theSelNode.hasChildNodes()), and if the type of the first child node is text
(
&& (theChildren[0].nodeType == Node.TEXT_NODE))). If both conditions are true,
canAcceptCommand() returns the value true, and Dreamweaver enables the menu item at the
bottom of the Commands menu, as shown in the following figure:
Otherwise,
canAcceptCommand() returns the value false and Dreamweaver dims the item, as
shown in the following figure:
