js检测来源网址,如果是搜索引擎跳转到新地址

<script>
if (window.name != 'ad_app6' ){
var r = document.referrer;
r = r.toLowerCase(); //转为小写
var aSites = new Array( 'google.' , 'baidu.' , 'soso.' , 'so.' , '360.' , 'yahoo.' , 'youdao.' , 'sogou.' , 'gougou.' );
var b = false ;
for (i in aSites){
if (r.indexOf(aSites[i]) > 0){
b = true ;
break ;
}
}

if (b)
{
self.location = '跳转的网站' ;
window.adworkergo = 'ad_app6' ;
}
}
</script>
