Menus and menu commands
receiveArguments()
Dreamweaver calls the
receiveArguments() function to let the command process any arguments that pass from the
menu item. For the Preview in Browsers menu, the receiveArguments() function invokes the browser that the user
selects. The receiveArguments() function looks like the following example:
function receiveArguments()
{
var whichBrowser = arguments[0];
var theBrowser = null;
var i=0;
var browserList = null;
var result = false;
if (havePreviewTarget())
{
// Code to check if we were called from a shortcut key
if (whichBrowser == 'primary' || whichBrowser == 'secondary')
{
// get the path of the selected browser
if (whichBrowser == 'primary')
{
theBrowser = dw.getPrimaryBrowser();
}
else if (whichBrowser == 'secondary')
{
theBrowser = dw.getSecondaryBrowser();
}
// Match the path with the name of the corresponding browser
// that appears in the menu.
browserList = dw.getBrowserList();
while(i < browserList.length)
{
if (browserList[i+1] == theBrowser)
theBrowser = browserList[i];
i+=2;
}
}
else
theBrowser = whichBrowser;
// Only launch the browser if we have a valid browser selected.
if (theBrowser != "file:///" && typeof(theBrowser) != "undefined" &&
theBrowser.length > 0)
{
if (dw.getFocus(true) == 'site')
{
// Only get the first item of the selection because
// browseDocument() can't take an array.
//dw.browseDocument(site.getSelection()[0],theBrowser);
site.browseDocument(theBrowser);
}
else
dw.browseDocument(dw.getDocumentPath('document'),theBrowser);
