   $(document).ready(function(){
        //$("#clickMeBtn").bind("click",clickHandler1);
        //$("#clickMeBtn").bind("click",clickHandler2);
       // $("#clickMeBtn").unbind("click",clickeHandler1);

        $("#clickMeBtn").on("click",clickHandler1);
        $("#clickMeBtn").on("click",clickHandler2);
        $("#clickMeBtn").off("click",clickeHandler1);
    });

   function clickHandler(e){
             console.log("clickHandler1")
  }
  function clickHandler(e){
             console.log("clickHandler2")
   }

3.事件的目标和事件冒泡

阻止事件冒泡的API:
event.stopPropagation() //阻止父级的冒泡事件
event.stopImmediatePropagation()// 阻止所有的冒泡事件

5.自定义事件

var ClickMeBtn;
$(doucument).ready(function){
      ClickMeBtn = $("#ClickMeBtn");
      ClickMeBtn.click(function(){
               var e =jQuery.Event("MyEvent");
               ClickMeBtn.trigger(e);
});
     ClickMeBtn.bind("MyEvent",function(event)){
                 console.log(event);
})
});
