js判断PC端或移动端及浏览器类型

判断是否pc还是移动

​
if ((navigator.userAgent.match(/(phone|pad|pod|iPhone|iPod|ios|iPad|Android|Mobile|BlackBerry|IEMobile|MQQBrowser|JUC|Fennec|wOSBrowser|BrowserNG|WebOS|Symbian|Windows Phone)/i))) {alert(&＃39;手机端&＃39;)
}else{alert(&＃39;PC端&＃39;)
}​

判断是什么类型的浏览器

function(){return {isSafari: (navigator.userAgent.indexOf(&＃39;Safari&＃39;)>&＃61;0 || navigator.userAgent.indexOf(&＃39;WebKit&＃39;)>&＃61;0)? true:false,isOpera: (window.opera && navigator.userAgent.indexOf(&＃39;Opera&＃39;)>&＃61;0)? true:false,isChrome:(navigator.userAgent.indexOf(&＃39;Chrome/&＃39;)>&＃61;0 && navigator.userAgent.indexOf(&＃39;WebKit&＃39;)>&＃61;0)? true:false,domAPI:(document && document.createElement)? true:false,isMac:(navigator.userAgent.indexOf(&＃39;Mac&＃39;)>&＃61;0)? true:false,}
}

其他方式&＃xff1a;

第一种&＃xff0c;只区分浏览器&＃xff0c;不考虑版本


function myBrowser(){var userAgent &＃61; navigator.userAgent; //取得浏览器的userAgent字符串var isOpera &＃61; userAgent.indexOf("Opera") > -1;if (isOpera) {return "Opera"}; //判断是否Opera浏览器if (userAgent.indexOf("Firefox") > -1) {return "FF";} //判断是否Firefox浏览器if (userAgent.indexOf("Chrome") > -1){return "Chrome";}if (userAgent.indexOf("Safari") > -1) {return "Safari";} //判断是否Safari浏览器if (userAgent.indexOf("compatible") > -1 && userAgent.indexOf("MSIE") > -1 && !isOpera) {return "IE";}; //判断是否IE浏览器
}//以下是调用上面的函数
var mb &＃61; myBrowser();
if ("IE" &＃61;&＃61; mb) {alert("我是 IE");
}
if ("FF" &＃61;&＃61; mb) {alert("我是 Firefox");
}
if ("Chrome" &＃61;&＃61; mb) {alert("我是 Chrome");
}
if ("Opera" &＃61;&＃61; mb) {alert("我是 Opera");
}
if ("Safari" &＃61;&＃61; mb) {alert("我是 Safari");
}

第二种&＃xff0c;区分浏览器&＃xff0c;并考虑IE5.5 6 7 8

function myBrowser(){var userAgent &＃61; navigator.userAgent; //取得浏览器的userAgent字符串var isOpera &＃61; userAgent.indexOf("Opera") > -1; //判断是否Opera浏览器var isIE &＃61; userAgent.indexOf("compatible") > -1 && userAgent.indexOf("MSIE") > -1 && !isOpera; //判断是否IE浏览器var isFF &＃61; userAgent.indexOf("Firefox") > -1; //判断是否Firefox浏览器var isSafari &＃61; userAgent.indexOf("Safari") > -1; //判断是否Safari浏览器if (isIE) {var IE5 &＃61; IE55 &＃61; IE6 &＃61; IE7 &＃61; IE8 &＃61; false;var reIE &＃61; new RegExp("MSIE (\\d&＃43;\\.\\d&＃43;);");reIE.test(userAgent);var fIEVersion &＃61; parseFloat(RegExp["$1"]);IE55 &＃61; fIEVersion &＃61;&＃61; 5.5;IE6 &＃61; fIEVersion &＃61;&＃61; 6.0;IE7 &＃61; fIEVersion &＃61;&＃61; 7.0;IE8 &＃61; fIEVersion &＃61;&＃61; 8.0;if (IE55) {return "IE55";}if (IE6) {return "IE6";}if (IE7) {return "IE7";}if (IE8) {return "IE8";}}//isIE endif (isFF) {return "FF";}if (isOpera) {return "Opera";}
}//myBrowser() end
//以下是调用上面的函数
if (myBrowser() &＃61;&＃61; "FF") {alert("我是 Firefox");
}
if (myBrowser() &＃61;&＃61; "Opera") {alert("我是 Opera");
}
if (myBrowser() &＃61;&＃61; "Safari") {alert("我是 Safari");
}
if (myBrowser() &＃61;&＃61; "IE55") {alert("我是 IE5.5");
}
if (myBrowser() &＃61;&＃61; "IE6") {alert("我是 IE6");
}
if (myBrowser() &＃61;&＃61; "IE7") {alert("我是 IE7");
}
if (myBrowser() &＃61;&＃61; "IE8") {alert("我是 IE8");
}

单独区分谷歌和safari的

//谷歌
if(navigator.userAgent.toLowerCase().indexOf("chrome") > 0) {alert("!")}//Safariif(navigator.userAgent.toLowerCase().indexOf("safari") > 0 && navigator.userAgent.toLowerCase().indexOf("chrome") <0){alert("2")}
