The Commands API 177

Example

The following example of the canAcceptCommand() function makes the command available

only when the selection is a table:

function canAcceptCommand(){

var retval=false;

var selObj=dw.getDocumentDOM.getSelectedNode();

return (selObj.nodeType == Node.ELEMENT_NODE && ¬

selObj.tagName=="TABLE");{

retval=true;

}

return retval;

}

commandButtons()

Description

This function defines the buttons that should appear on the right side of the Options dialog

box and their behaviors when they are clicked. If this function is not defined, no buttons

appear, and the

BODY section of the Commands file expands to fill the entire dialog box.

Arguments

None.

Returns

Dreamweaver expects an array that contains an even number of elements. The first element is

a string that contains the label for the topmost button. The second element is a string of

JavaScript code that defines the behavior of the topmost button when it is clicked. The

remaining elements define additional buttons in the same way.

Example

The following instance of commandButtons() defines three buttons: OK, Cancel, and Help:

function commandButtons(){

return new Array("OK" , "doCommand()" , "Cancel" , ¬

"window.close()" , "Help" , "showHelp()");

}
