超简陋浏览器
时间：2020-12-02 12:52:56|栏目：DOS/BAT|点击： 次
可是那些破站点让人太郁闷了...不是弹出广告，就是满屏幕飘浮动广告....气死我了...
所以做了一个超简陋的浏览器，把页面中的 JS 基本上全禁掉了（禁用JS的正则不是很好，此外CSS里的没禁掉，不过目前反正够俺用就好了），顺便把 iframe 也全部干掉
还可以自动记得上次浏览的页面，打开就直接进入，看书的时候就不怕打断了
因为超简陋，所以连 表单也不支持，只支持链接，哈哈，看书倒是够用了....
代码中的 伪session 处理 和 俺自己封装的 xmlhttp 值得一看
不能直接运行，保存到本地，另存为 HTA 使用，哈哈
