摘要: JavaScript应用实例：点出统计器
<tr>
<td>
ff 默认不让改 status
opera9 测试通过
ie6 测试通过
这东西是给统计部门用的，分析用户习惯以改良网站布局。
只是写着玩的小东西，所以很多地方不太理想。
save() 方法是保存记录的,没仔细做,应该再加个判断浏览器,然后决定用 img 还是 iframe,以保证 request 一定能发出去.
onclick() 方法是触发事件时执行的
使用方法：
在任意页面中加入
CODE:
script src="clickout.js"></script>
最好是放在 </body> 前面，目的是防止 onclick 事件覆盖。
clickout.js
CODE:
