  • JS判断移动端访问设备并加载对应CSS样式

     

     

    JS判断不同web访问环境,主要针对移动设备,提供相对应的解析方案(判断设备代码直接copy腾讯网的) 

    复制代码
    // 判断是否为移动端运行环境 
    
    if(/AppleWebKit.*Mobile/i.test(navigator.userAgent) || (/MIDP|SymbianOS|NOKIA|SAMSUNG|LG|NEC|TCL|Alcatel|BIRD|DBTEL|Dopod|PHILIPS|HAIER|LENOVO|MOT-|Nokia|SonyEricsson|SIE-|Amoi|ZTE/.test(navigator.userAgent))){ 
    
    if(window.location.href.indexOf("?mobile")<0){ 
    
    try{ 
    
    if(/Android|webOS|iPhone|iPod|BlackBerry/i.test(navigator.userAgent)){ 
    
    // 判断访问环境是 Android|webOS|iPhone|iPod|BlackBerry 则加载以下样式 
    
    setActiveStyleSheet("style_mobile_a.css"); 
    
    } 
    
    else if(/iPad/i.test(navigator.userAgent)){ 
    
    // 判断访问环境是 iPad 则加载以下样式 
    
    setActiveStyleSheet("style_mobile_iPad.css"); 
    
    } 
    
    else{ 
    
    // 判断访问环境是 其他移动设备 则加载以下样式 
    
    setActiveStyleSheet("style_mobile_other.css"); 
    
    } 
    
    } 
    
    catch(e){} 
    
    } 
    
    } 
    
    else{ 
    
    // 如果以上都不是,则加载以下样式 
    
    setActiveStyleSheet("style_mobile_no.css"); 
    
    } 
    
    // 判断完毕后加载样式 
    
    function setActiveStyleSheet(filename){document.write("<link href="+filename+" rel=stylesheet>");} 
    复制代码

    加载页面 

    复制代码
    <script type="text/javascript"> 
    if(/AppleWebKit.*mobile/i.test(navigator.userAgent) || (/MIDP|SymbianOS|NOKIA|SAMSUNG|LG|NEC|TCL|Alcatel|BIRD|DBTEL|Dopod|PHILIPS|HAIER|LENOVO|MOT-|Nokia|SonyEricsson|SIE-|Amoi|ZTE/.test(navigator.userAgent))){ 
    if(window.location.href.indexOf("?mobile")<0){ 
    try{ 
    if(/Android|webOS|iPhone|iPod|BlackBerry/i.test(navigator.userAgent)){ 
    window.location.href="手机页面"; 
    }else if(/iPad/i.test(navigator.userAgent)){ 
    window.location.href="平板页面"; 
    }else{ 
    window.location.href="其他移动端页面" 
    } 
    }catch(e){} 
    } 
    } 
    </script>
