<body>
<h1 id="a">你好</h1>
<script>
// getElementById,通過id獲取元素
var getDom = function (id){
return document.getElementById(id);
};
// 給元素綁定事件
var addEvent = function(id,event,fn){
var el = getDom(id)||document;
//非IE瀏覽器
if(el.addEventListener){
el.addEventListener(event,fn)
}else if(el.attachEvent){
el.attachEvent('on'+event,fn);
}
};
</script>
</body>
</html>
瀏覽器是360的，getDom是可用的；
getDom('a')
<h1 id="a">你好</h1>
addEvent('a','click',function(){alert(5)})
undefined

嗯，可我加上之后，還是不行，瀏覽器是360的，下面是我重新試的，getDom是可用的；
getDom('a')
<h1 id="a">你好</h1>
addEvent('a','click',function(){alert(5)})
undefined

你漏了“）”這個。你調(diào)用addEvent?('search_form','click',function(){alert(5)}）
