function getDynamicContent(itemID)

{

var browsers = null;

var PIB = null;

var i;

var j=0;

browsers = new Array();

PIB = dw.getBrowserList();

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 the Preferences dialog box. 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 quotation marks (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 the Preferences dialog box, the

getDynamicContent() function returns

the array

browsers to Dreamweaver. If no browsers have been selected, 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.
