js如何判断是手机还是电脑浏览器？,第1张

应该把JS 放在页面首页加载 就行

function IsPC() {

var userAgentInfo = navigator.userAgent

var Agents = ["Android", "iPhone",

"SymbianOS", "Windows Phone",

"iPad", "iPod"]

var flag = true

for (var v = 0v <Agents.lengthv++) {

if (userAgentInfo.indexOf(Agents[v]) >0) {

flag = false

break

}

}

return flag

}

var flag = IsPC()//true为PC端，false为手机端

alert(flag)

<script type=”text/javascript”><!— //平台、设备和操作系统var system ={win : false,mac : false,xll : false}//检测平台var p = navigator.platformsystem.win = p.indexOf(“Win”) == 0system.mac = p.indexOf(“Mac”) == 0system.x11 = (p == “X11”) (p.indexOf(“Linux”) == 0)//跳转语句if(system.winsystem.macsystem.xll){}else{window.location.href=”android.aspx”}—></script>
