建议站长及web开发人员使用如下压缩后的js脚本

复制代码 代码如下:

function uaredirect(f){try{if(document.getElementById("bdmark")!=null){return}var b=false;if(arguments[1]){var e=window.location.host;var a=window.location.href;if(isSubdomain(arguments[1],e)==1){f=f "/#m/" a;b=true}else{if(isSubdomain(arguments[1],e)==2){f=f "/#m/" a;b=true}else{f=a;b=false}}}else{b=true}if(b){var c=window.location.hash;if(!c.match("fromapp")){if((navigator.userAgent.match(/(iPhone|iPod|Android|ios)/i))){location.replace(f)}}}}catch(d){}}function isSubdomain(c,d){this.getdomain=function(f){var e=f.indexOf("://");if(e>0){var h=f.substr(e 3)}else{var h=f}var g=/^www./;if(g.test(h)){h=h.substr(4)}return h};if(c==d){return 1}else{var c=this.getdomain(c);var b=this.getdomain(d);if(c==b){return 1}else{c=c.replace(".","\.");var a=new RegExp("\." c "$");if(b.match(a)){return 2}else{return 0}}}};
