JS判断是PC还是移动端浏览器，并根据不同的终端跳转到不同的网址

<script>
function browserRedirect() {
    var sUserAgent = navigator.userAgent.toLowerCase();
    var bIsIpad = sUserAgent.match(/ipad/i) == "ipad";
    var bIsIphoneOs = sUserAgent.match(/IPHONE os/i) == "iphone os";
    var bIsMidp = sUserAgent.match(/midp/i) == "midp";
    var bIsUc7 = sUserAgent.match(/rv:1.2.3.4/i) == "rv:1.2.3.4";
    var bIsUc = sUserAgent.match(/ucweb/i) == "ucweb";
    var bIsAndroid = sUserAgent.match(/android/i) == "android";
    var bIsCE = sUserAgent.match(/windows ce/i) == "windows ce";
    var bIsWM = sUserAgent.match(/windows mobile/i) == "windows mobile";
    if (!(bIsIpad || bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM) ){
        window.location.href="http://blog.csdn.net/bysjlwdx";
    } else {
        window.location.href="http://m.blog.csdn.net/blog/index?username=bysjlwdx";
    }
}
browserRedirect();
</script>

如果是pc端访问移动网址，则需要跳转到相应的pc网址，修改上面代码如下(将js代码放到移动页面检测)：

if (!(bIsIpad || bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM) ){
        var url = window.location.href;
		url2 = url.replace('abc.com.cn/m','abc.com.cn');
		window.location.href = url2;
    }

if (bIsIpad || bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM){
        var url = window.location.href;
		url2 = url.replace('abc.com.cn','abc.com.cn/m');
		window.location.href = url2;
    }
