			 *判断浏览器窗口是刷新或者关闭操作
			 * 无论任何浏览器不管是刷新或者是关闭都会执行下面两个方法 onbiforeunload  onunload
			 * 根据时间差来实现
			 * 在点击刷新或者关闭时开始计时记录下这一刻的时间戳
			 * 因为刷新和关闭 在执行onunload方法时的时间不一样，一般情况下经过测试
			 * 关闭时时间差不大于3毫秒
			 * 刷新时即使只有一个简单的helloworld页面都不少于10毫秒
			 * 而一般网站网页内容更多，时间差达到了100多毫秒
			 *
			 *
			 * 下面方法的缺点是不管你开了多少窗口，都会在关闭一个窗口时清空所有localStorage缓存
			 * 造成所有页面都需要重新登录，其实这也是针对项目而言的，目前本项目就不认为这是缺点
			 * 而能更好的保护用户信息
