jQuery.bind()事件在简单的Javascript对象上

var myClass = function(){
    this._callBACks = {};
};
myClass.prototype = {
  addEvent: function(evname,callBACk) {
    if (!this._callBACks[evname]) {
      this._callBACks[evname] = $.CallBACks();
    }
    this._callBACks[evname].add(callBACk);
  },removeEvent: function(evName) {
    if (!this._callBACks[evname]) {
      return;
    }
    this._callBACks[evname].remove();
    //Might need this too:
    //this._callBACks[evname] = null;
  },triggerEvent: function(evName) {
    if (this._callBACks[evname]) {
      this._callBACks[evname].fire();
    }
  }
};
var foo = new myClass();
foo.addEvent("foo",function(){
  console.log('foo');
});
foo.triggerEvent("foo");
foo.removeEvent("foo");
// event was removed,the below line won't do anything.
foo.triggerEvent("foo");

然而,为了回答你的问题,除了没有记录的事情之外,我看不到任何即时的问题,而且可能会将功能从版本更改为版本(尽管它在所有当前可用的版本1.2.6中都有效).
