<h1>Welcome to jquery registry event test</h1>
<button id="onWayToEvent" >通过on的方式多次注冊事件</button>  </br>
<div class="info">
通过 on方法注冊的事件,每次的注冊不会把原来的方法覆盖掉。

会以队列的形式保存起来
点击的时候,触发事情会一个个按注冊的顺序运行。


主要代码:
function initOnEvent(){
//为id为onWayToEvent button注冊点击事件
$("#onWayToEvent").on("click",function(){
alert("this is one on event")
});
$("#onWayToEvent").on("click",function(){
alert("this is two on event")
});
$("#onWayToEvent").on("click",function(){
alert("this is three on event")
});
}

</div>
<button id="bindWayToEvent">通过bind的方法多次注冊事件</button>

<div class="info" >
通过 jquery 的bind方法多次注冊的方法也是一样,不会把原来的方法覆盖了,也是把方法以
队列的形式保存起来。触发事件后按注冊次序逐个运行。

主要代码:
function initBindEvent(){
//为id为bindWayToEvent 的button注冊点击事件
$("#bindWayToEvent").bind("click",function(){
alert("this is registry event by bind. one")
});

$("#bindWayToEvent").bind("click",function(){
alert("this is registry event by bind. two")
});

$("#bindWayToEvent").bind("click",function(){
alert("this is registry event by bind. three")
});
}

</div>

<button id="clickWayToEvent">通过click方法多次注冊事件</button>
<div class="info" >
通过 jquery 的click方法多次注冊的方法也是上面的效果一样 。


主要代码:
function initClickvent(){
$("#clickWayToEvent").click(function(){
alert("this is registry event by click. one");
});

$("#clickWayToEvent").click(function(){
alert("this is registry event by click. two");
});
$("#clickWayToEvent").click(function(){
alert("this is registry event by click. three");
});
}

</div>
<button id="liveWayToEvent">通过live 方法多次注冊事件</button>
<div class="info" >
 要怎么样才干把前面的事件给覆盖掉。仅仅保留最后注冊的事件方法?
</div>

<button id="oneEvnetByBind">通过unbind,bind方法进行事件的唯一注冊</button>
<div class="info">
这种方法能够行得通
主要代码:
function oneEventByBindUnBind(){
 
registryManyEvent("oneEvnetByBind");
$("#oneEvnetByBind").unbind("click").bind("click",function(){
alert("only you !!!!!!!");
});

}

 

function registryManyEvent(id){
$("#"+id).click(function(){
alert("this is registry event by common. one");
});

$("#"+id).click(function(){
alert("this is registry event by common. two");
});
$("#"+id).click(function(){
alert("this is registry event by common. three");
});
}

</div>

<button id="oneEvnetByDieLive">通过 die live 方法进行事件的唯一载入</button>
<div class="info">
我们用的 jquery-1.10.2.js 这里没有提供 die live 方法。

对于网上提供的这种方法是无效的。
主要代码:
function oneEvnetByDieLive(){
registryManyEvent("oneEvnetByDieLive");
$("#oneEvnetByDieLive").die().live("click",function(){

alert("the one of you !!!!!!");
});
}

function registryManyEvent(id){
$("#"+id).click(function(){
alert("this is registry event by common. one");
});

$("#"+id).click(function(){
alert("this is registry event by common. two");
});
$("#"+id).click(function(){
alert("this is registry event by common. three");
});
}

</div>
