js判断是pc还是移动端

<script type="text/javascript"> /** * 获取客户端信息 */ function getClientInfo() { var userAgentInfo = navigator.userAgent; var Agents = new Array("Android", "iPhone", "SymbianOS", "Windows Phone", "iPad", "iPod"); var agentinfo = null; for (var i = 0; i < Agents.length; i++) { if (userAgentInfo.indexOf(Agents[i]) > 0) { agentinfo = userAgentInfo; break; } } if (agentinfo) { return agentinfo; } else { return "PC"; } } //调用示例 alert(getClientInfo()); </script>

1、pc端写 （如果是移动端跳走）

!function(){ function params(u, p){ var m = new RegExp("(?:&|/?)"+p+"=([^&$]+)").exec(u); return m ? m[1] : ''; } if(/iphone|ios|android|ipod/i.test(navigator.userAgent.toLowerCase()) == true && params(location.search, "from") != "mobile"){ location.href = 'http://m.XXX.com'; } }();

2、移动端写 （如果打开是pc跳走）

!function(){ if(/iphone|ios|android|ipod/i.test(navigator.userAgent.toLowerCase()) == false){ location.href = 'http://XXX.com'; } }();
