复制代码 代码如下:

// 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")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("");}
