Url link in UI

Here is an example of what I use to display a web page (to run directly from After Effects) :

var win = new Window ("dialog");

var winBrowserCmd = "C:/Program Files/Internet Explorer/iexplore.exe";

var macBrowserCmdStart = "osascript -e 'open location \"";

var macBrowserCmdEnd = "\"'";

var BtnURL = win.add("button", undefined, "Check for update"); // var BtnURL = win.add ("iconbutton", undefined, "~/Desktop/img.png" );

BtnURL.onClick = LinkToURL;

win.add ("button", undefined, "Close", {name: "ok"});

function LinkToURL()

        {

            var URL = "http://www.google.fr/"; // your web page

            if ($.os.indexOf("Windows") != -1)

                system.callSystem(winBrowserCmd + " " + URL);

            else

                system.callSystem(macBrowserCmdStart + URL + macBrowserCmdEnd);

        }

win.show ();

write to image click event:

system.callSystem("explorer.exe \"http://your.url.com\"") ;

option "Allow Scripts to Write Files and Access Network" must be true

P. S.

Study the Flash Builder is faster and more grateful than the JS interface.
