js中有一个对象叫 navigator,navigator 对象包含有关浏览器的信息。所有的浏览器都支持该对象。
其中经常用到的是 navigator.userAgent 属性,通常,它是在 navigator.appCodeName(浏览器的名称) 的值之后加上斜线和 navigator.appVersion 的值构成的。
判断是PC还是手机浏览器:
第一种:
function IsPC() { var userAgentInfo = navigator.userAgent; var Agents = ["Android", "iPhone","SymbianOS", "Windows Phone", "iPad", "iPod"]; var flag = true; for (var v = 0; v < Agents.length; v++) { if (userAgentInfo.indexOf(Agents[v]) > 0) { flag = false; break; } } return flag; }
第二种:
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"; if (!(bIsIpad || bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM) ){ window.location.href=B页面; } }
判断是安卓还是iOS
常用:
function ismobile(test){ var u = navigator.userAgent, app = navigator.appVersion; 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(/iPhone|mac|iPod|iPad/i.test(navigator.userAgent)){ return ‘0‘; }else{ return ‘1‘; } }catch(e){} } }else if( u.indexOf(‘iPad‘) > -1){ return ‘0‘; }else{ return ‘1‘; } };
