A dynamic menu example 203

for (i=0; i<PIB.length; i=i+2)

{

browsers[j] = new String(PIB[i]);

if (dw.getPrimaryBrowser() == PIB[i+1])

browsers[j] += "\tF12";

else if (dw.getSecondaryBrowser() == PIB[i+1])

browsers[j] += "\tCmd+F12";

browsers[j] += ";id='"+escQuotes(PIB[i])+"'";

if (itemID == "DWPopup_PIB_Default")

browsers[j] = MENU_strPreviewIn + browsers[j];

j = j+1;

}

return browsers;

}

The getDynamicContent() function calls the dw.getBrowserList() function to obtain an

array of the browser names that have been specified in the Preview in Browser section of

Dreamweaver Preferences. This array contains the name of each browser and the path to the

executable file. Next, for each item in the array

(i=0; i<PIB.length; i=i+2), the

getDynamicContents() function moves the name of the browser (PIB[i]) into a second

array called

browsers (browsers[j] = new String(PIB[i]);). If the browser has been

designated as the primary or secondary browser, the function appends the names of the

keyboard shortcut keys that invoke them. Next it appends the string

";id=" followed by the

name of the browser in single quotes (for example,

;id=’iexplore’). If the itemID

argument is "

DWPopup_PIB_Default", the function prefixes the array item with the string

Preview in. After it constructs an entry for each browser listed in Preferences, the

getDynamicContent() function returns the array browsers to Dreamweaver. If no browsers

have been selected in Preferences, the function returns the value

null, and Dreamweaver

displays No Browsers Selected in the menu.

canAcceptCommand()

Dreamweaver next calls the canAcceptCommand() function for each menuitem tag that

references a command file with the

file attribute. If the canAcceptCommand() function

returns the value

false, the menu item is dimmed. If the canAcceptCommand() function

returns the value

true, Dreamweaver enables the item on the menu. If the function returns

true or is not defined, Dreamweaver calls the isCommandChecked() function to determine

whether to display a check mark next to the menu item. If the

isCommandChecked() function

is not defined, no check mark appears.
