Porting Dojo Methods to Flash

<p>Mike Wilcox has started a nice series of posts on porting Dojo methods to Flash as a homage for Open Screen (aside: I applaud Adobe's intentions, but need to see a non-assert of their IP before I can do anything with it.)

In part one of the series Mike ports dojo.hitch to ActionScript:

PLAIN TEXT

JAVASCRIPT:

_global.lang = {
hitch: function(scope, method){
if(!method){
method = scope;
scope = _global;
}
var args;
if(arguments.length>2){
args = arguments;
args.shift();
args.shift();
}
if(typeof(method) == "string"){
return function(){ scope[method].apply(scope, args) };
}
return function(){ method.apply(scope, args) };
}
}

In part two he adds support for dojo.connect(), resulting in:

PLAIN TEXT

JAVASCRIPT:

_global.lang = {
__conListeners:{},
__id:0,
connect: function(source, event, target, callback){
var hitched = this._hitch(target, callback);
var listener = new Object();
listener[event] = function(args){
hitched();
}
if(!source.broadcasters) {
source.broadcasters = {};
AsBroadcaster.initialize(source)
}
source.addListener(listener);
if(!source.broadcasters[event]){
source[event] = function(){
source.broadcastMessage(event, arguments);
}
source.broadcasters[event] = true;
}
var id = "connect_"+this.__id++;
this.__conListeners[id] = {listener:listener, source:source};
return id;
}
disconnect: function(id){
var con = this.__conListeners[id];
if(con){
con.source.removeListener(con.listener);
con = null;
}
}
}
