"wrapper": All (non AIR) Flex apps run in the Flash Player, which is in
turn hosted in an Html file, which is rendered by the browser. That
html file is often referred to as the "html wrapper". Flex Builder
generates the wrapper by default, naming it the same as your
application.
That function I posted goes in a javascript block in that html wrapper
file. I put my script in with the version declarations in the commented
area near the top.
You invoke the javascript "showHelp()" function from Flex using
ExternalInterface. Below is the code I use for my help.
Tracy
import flash.external.ExternalInterface;
public function
showHelp(sModuleId:String,sViewId:String="",sAnchor:String=""):void
{
var sFileName:String = sModuleId.toLowerCase();
if (sViewId.length > 0) {
sFileName += "_" + sViewId.toLowerCase();
}
sFileName += ".html";
if (sAnchor.length > 0) {
sFileName += "#" + sAnchor.toLowerCase();
}
var sLoadUrl:String = _sSiteAssetsUrl + "help/" + sFileName;
//trace(sLoadUrl)
ExternalInterface.call("showHelp", sLoadUrl);
}//

navigateToURL
There are a couple of things I'm not quite getting:
1) how do you invoke this from Flex?
2) what do you mean by your "wrapper"?
I understand the code below but I am still not really clear how it
gets invoked. Sorry for being so dim :-(
