RubyのObject.sendみたいなのをJavaScriptで実装

gistfile1.js

function a(b){
  alert(b)
}
Object.prototype.send = function(method, args) {
  var args = args instanceof Array ? args : [args]
  return this[method].apply(this, args)
}
function send(func, args) {
  var func = /\./.test(func) ? func.split(".") : func;
  var args = args instanceof Array ? args : [args]
  if(func instanceof Array) {
    var nest = window;
    for(var i = 0; i < func.length; i++)
      nest = nest[func[i]];
    return nest.apply(func[func.length - 1], args)
  }
  return window[func].apply(null, args)
}
bd = {
  c : function(d, e) {
    alert(d + e)
  }
}
send("a", ["v","f"]);
send("bd.c", ["foo", "bar"]);
alert("a,b,c".send("split", ",")[1])
