Javascript隨記

一, 理解Javascript的執行環境概念

function say(msg) {
  alert(this + ' says ' + msg);
}
var tt = {
  message: 'James ',
  say: function (thing) {
    alert(this.message + thing);
  }
}

var ss = {
  message: 'Alex ',
  say: function (thing) {
    alert(this.message + ' solve ' + thing);
  }
}

tt.say.call(ss, "Hello World");
// output: Alex Hello World
