使用JS让网站自动跳转到对应的WAP页面

这是之前在论坛看到的一种方法，特此记录，方便往后查阅

<script language="javascript">    (function () {        var res = GetRequest();        var par = res['pc']; //获取html附带的参加pc=1，如果不为1则跳转，为1不跳转。        if (par != '1') {            var ua = navigator.userAgent.toLowerCase();            var contains = function (a, b) {                if (a.indexOf(b) != -1) { return true; }            };            //将下面的网址改成你的wap手机版页面地址            var toMobileVertion = function () {                window.location.href = 'http://m.hpet.com.cn'            }            if (contains(ua, "ipad") || (contains(ua, "rv:1.2.3.4")) || (contains(ua, "0.0.0.0")) || (contains(ua, "8.0.552.237"))) { return false }            if ((contains(ua, "android") && contains(ua, "mobile")) || (contains(ua, "android") && contains(ua, "mozilla")) || (contains(ua, "android") && contains(ua, "opera"))        || contains(ua, "ucweb7") || contains(ua, "iphone")) { toMobileVertion(); }        }    })();    function GetRequest() {        var url = location.search; //获取url中"?"符后的字串        var theRequest = new Object();        if (url.indexOf("?") != -1) {            var str = url.substr(1);            strs = str.split("&");            for (var i = 0; i < strs.length; i++) {                theRequest[strs[i].split("=")[0]] = unescape(strs[i].split("=")[1]);            }        }        return theRequest;    }</script>
