超简陋浏览器

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>
<meta http-equiv="content-type" content="text/html; charset=UTF-8" />
<style>
body { margin:0px; padding:0px; overflow:auto; border-style:none; font-size:12px; background-color:buttonface; }
iframe { width:100%; border-style:none; position:absolute; top:25px; }

#i1 { height:22px; line-height:18px; width:100%; border:1px solid #666; margin:0px 2px; padding:0px 10px; }
</style>
<script>
strSessionName="bookviewer_lastURL";
lastURL="";
xp=new xmlhttp();

function checkMe(){
    if(i1.value!=lastURL){
        lastURL=i1.value;
        session_set(strSessionName,lastURL);
    }
    try{
        for(var i=0;i<f1.document.links.length;i++)f1.document.links[i].onclick=n0;
    }catch(e){}
    if(/book\.5seecn/i.test(lastURL))f1.document.body.onkeydown=chkKey;
}

function chkKey(){
