本文介绍一个用于统计部门分析用户习惯的JavaScript点击统计器。该工具通过记录用户点击行为辅助网站布局改良，兼容Firefox、Opera及IE6浏览器。文章提供了完整的代码引入方式、save()与onclick()方法说明，以及防止事件覆盖的最佳实践建议。
点击统计器概述与兼容性
Firefox浏览器默认禁止修改status属性。
该代码已在Opera 9版本中测试通过。
该代码已在IE 6版本中测试通过。
工具用途与局限性
此工具主要面向统计部门，旨在通过分析用户习惯来改良网站布局。
这只是一个用于练习的小项目，因此部分功能尚不完善。
核心方法说明
save()方法用于保存记录，由于未做细致处理，建议增加浏览器判断逻辑，根据浏览器类型选择使用img或iframe，以确保请求能够成功发送。
onclick()方法用于在触发点击事件时执行相应操作。
代码引入与最佳实践
具体使用方法如下：
在任意页面中引入以下代码：
<script src="clickout.js"></script>
建议将脚本放置在</body>标签之前，目的是防止onclick事件被覆盖。
