A dynamic menu example 201

The setMenuText() function looks like the following example code:

function setMenuText()

{

if (arguments.length != 1) return "";

var whatToDo = arguments[0];

if (whatToDo == "undo")

return dw.getUndoText();

else if (whatToDo == "redo")

return dw.getRedoText();

else return "";

}

Placing the command file in the Menu folder

To implement the menu Undo and Redo menu items, you must save the MyMenu.htm

command file in the Dreamweaver Configuration/Menus folder or a subfolder that you

create. The location of the file must agree with the location that you specified in the

menuitem tag. To make it accessible to Dreamweaver, either restart Dreamweaver or reload

extensions. For information on how to reload extensions, see “Reloading extensions”

on page 104.

To run the menu commands, select the menu item when it is enabled. Dreamweaver will

invoke the functions in the command file, as described in “How menu commands work”

on page 196.

A dynamic menu example

This example implements the Dreamweaver Preview in Browser submenu that displays a list

of available browsers. The example also opens the current file, or the selected files in the Site

panel, in the user-specified browser. Implementing this dynamic menu consists of the

following steps:

■ Creating the dynamic menu items

■ Writing the JavaScript code
