js determines whether it is PC or mobile-JS Tutorial-php.cn

本文主要和大家分享js判断是PC端还是移动端的方法，希望能帮助到大家。

#### 方案1：" 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; } "

Copy after login

#### 方案2：

" 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; } } browserRedirect(); "

Copy after login

#### 方案3：

" var browser_class = navigator.userAgent; var browser_class_name1 = browser_class.match("Mobile"); var browser_class_name2 = browser_class.match("mobile"); var location_url = window.location.href; if (browser_class_name1 != null || browser_class_name2 != null) { if (location_url.match("wap") == null) { window.location.href = "http://wap.xxxx.com"; } } else { if (location_url.match("3g") != null || location_url.match("wap") != null) { window.location.href = "http://wap.xxxx.com"; } } "

Copy after login

#### 百度方案：

" function uaredirect(f) { try { if (document.getElementById("bdmark") != null) { return } var b = false; if (arguments[1]) { var e = window.location.host; var a = window.location.href; if (isSubdomain(arguments[1], e) == 1) { f = f + "/#m/" + a; b = true } else { if (isSubdomain(arguments[1], e) == 2) { f = f + "/#m/" + a; b = true } else { f = a; b = false } } } else { b = true } if (b) { var c = window.location.hash; if (!c.match("fromapp")) { if ((navigator.userAgent.match(/(iPhone|iPod|Android|ios|SymbianOS)/i))) { location.replace(f) } } } } catch(d) {} } function isSubdomain(c, d) { this.getdomain = function(f) { var e = f.indexOf("://"); if (e > 0) { var h = f.substr(e + 3) } else { var h = f } var g = /^www\./; if (g.test(h)) { h = h.substr(4) } return h }; if (c == d) { return 1 } else { var c = this.getdomain(c); var b = this.getdomain(d); if (c == b) { return 1 } else { c = c.replace(".", "\\."); var a = new RegExp("\\." + c + "$"); if (b.match(a)) { return 2 } else { return 0 } } } }; "

#### 类似方案：

" //判断访问的设备信息 var ua = window.navigator.userAgent.toLowerCase(); if (ua.indexOf('android') != -1) { window.location = path + "/DownloadSoftWare/" + name + "/" + id+ "/"; } else if (ua.indexOf('iphone') != -1 || ua.indexOf('ipad') != -1) { window.top.location = "苹果官网"; } else if (ua.indexOf("Window NT")) { window.top.location = path + "/"; } else { alert("sorry，暂不支持您的系统下载！！"); } "
