关于pc/wap端链接跳转适配问题

PC端代码：

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";  
    var uurl =window.location.href;
    if (bIsIpad || bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM) {  
        if(uurl.indexOf("http://m.")!=0){
            if(uurl.indexOf("#fromapp")>0){
                window.location.href = uurl;
            }else{
                window.location.href = uurl.replace("http://","http://m.");
            }
        }
    } 
    
}  
browserRedirect();

WAP端代码：

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";  
    var uurl =window.location.href;
    if (bIsIpad || bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM) {
        
    } 
    else{
        if(uurl.indexOf("http://m.")==0){
            window.location.href = uurl.replace('http://m.', 'http://');
        }
    }
}  
browserRedirect();
