202 Menus and Menu Commands

Creating the dynamic menu items

The following menu tags in the menus.xml file define the Preview in Browser submenu of the

File menu:

<menuitem dynamic name="No Browsers Selected"

file="Menus/MM/PIB_Dynamic.htm" arguments="'No Browsers'"

id="DWMenu_File_PIB_Default" />

<menuitem name="_Edit Browser List..." enabled="true"

command="dw.editBrowserList()" id="DWMenu_File_PIB_EditBrowserList" />

</menu>

The first menuitem tag defines the default menu item No Browsers Selected, which appears

on the submenu if you have not specified any browsers for the Preview in Browser item in

Preferences. If you specified the Microsoft Internet Explorer browser, however, the submenu

would look like the following figure:

The

name attribute for the first menu item specifies the command file PIB_Dynamic.htm.

This file contains the following line:

The script tag includes the JavaScript code in the PIB_Dynamic.js file, which supplies the

JavaScript code that interacts with the Preview in Browser submenu. This code could be saved

directly in the PIB_Dynamic.htm file, but storing it in a separate file allows multiple

commands to include the same code.

Writing the JavaScript code

Because the first menuitem tag contains the dynamic attribute, Dreamweaver calls the

getDynamicContent() function in the PIB_Dynamic.js file, which is shown in the following

example:

function getDynamicContent(itemID)

{

var browsers = null;

var PIB = null;

var i;

var j=0;

browsers = new Array();

PIB = dw.getBrowserList();
