超简陋浏览器

发布时间:2022-04-17 发布网站:脚本宝典
脚本宝典收集整理的这篇文章主要介绍了超简陋浏览器脚本宝典觉得挺不错的,现在分享给大家,也给大家做个参考。
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
复制代码 代码如下:

<head>
<title>Book Viewer</title>
