## 单击事件
```javascript
<a href="http://www.baidu.com">百度</a>
<script type="text/javascript">
//获取元素
var a = document.getElementsByTagName('a')[0];

//单击事件
a.onclick = function() {
    alert('我是百度的连接哦!!!!');
    //阻止元素的默认行为
    return false;
}
</script>
```

### e.g.
```html
<style type="text/css">
    *{
        list-style:none;
        padding:0px;
        margin:0px;
    }
    li{
        width:150px;
        height:150px;
        float:left;
    }
</style>
<ul>
    <li style="background:#6666FF"></li>
    <li style="background:#99CC00"></li>
    <li style="background:#99FFFF"></li>
    <li style="background:#CC00FF"></li>
    <li style="background:#CC66CC"></li>
</ul>
<script type="text/javascript">
//获取li元素
var lis = document.getElementsByTagName('li');
//绑定单击事件
for(var i=0;i<lis.length;i++) {
    lis[i].onclick = function(){
        //获取当前正在点击的这个元素的背景颜色
        var color = this.style.background;
        //修改body背景颜色
        document.getElementsByTagName('body')[0].style.background = color;
    }
}
</script>
```

  Nam liber tempor cum soluta nobis eleifend option congue nihil imperdiet doming id quod mazim placerat facer possim assum. Typi non habent claritatem insitam; est usus legentis in iis qui facit eorum claritatem. Investigationes demonstraverunt lectores legere me lius quod ii legunt saepius. Claritas est etiam processus dynamicus, qui sequitur mutationem consuetudium lectorum. Mirum est notare quam littera gothica, quam nunc putamus parum claram, anteposuerit litterarum formas humanitatis per seacula quarta decima et quinta decima. Eodem modo typi, qui nunc nobis videntur parum clari, fiant sollemnes in futurum.
