<body>
<div id="test"> js</div>
<div id="jquery"> jquery</div>
<div>e.target是html对象，html对象转字符串直接变成[object HTMLDivElement]。所以要获取htmldom的话用event.target.innerHTML等</div>
<div>console.log()能打印object对象，所以log看到了值。造成假象。</div>

<script type="text/javascript">
document.getElementById("test").onclick = function(e){
console.log(e.target);
console.log("ddd"+e.target);
}
$("#jquery").click(function(e){
console.log("ddd"+e.target);
var obj = {id:"dis",name:"name"};
console.log("my"+obj);
var s = e.target;
alert(s);
});
</script>

单击<div>js</div> log值：
<div id="test"> js</div>
ddd[object HTMLDivElement]
