function getDynamicContent(itemID)
{
var browsers = null;
var PIB = null;
var i;
var j=0;
browsers = new Array();
PIB = dw.getBrowserList();
for (i=0; i{
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
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.
