js判断浏览器类型代码如下：function myBrowser() { var userAgent = navigator.userAgent; //取得浏览器的userAgent字符串 var isOpera = userAgent.indexOf("Opera") > -1; //判断是否Opera浏览器 var isIE
js判断浏览器类型代码如下：
function myBrowser() { var userAgent = navigator.userAgent; //取得浏览器的userAgent字符串 var isOpera = userAgent.indexOf("Opera") > -1; //判断是否Opera浏览器 var isIE = userAgent.indexOf("compatible") > -1 && userAgent.indexOf("MSIE") > -1 && !isOpera; //判断是否IE浏览器 var isEdge = userAgent.indexOf("Edge") > -1; //判断是否IE的Edge浏览器 var isFF = userAgent.indexOf("Firefox") > -1; //判断是否Firefox浏览器 var isSafari = userAgent.indexOf("Safari") > -1 && userAgent.indexOf("Chrome") == -1; //判断是否Safari浏览器 var isChrome = userAgent.indexOf("Chrome") > -1 && userAgent.indexOf("Safari") > -1; //判断Chrome浏览器 if (isIE) { var reIE = new RegExp("MSIE (//d+//.//d+);"); reIE.test(userAgent); var fIEVersion = parseFloat(RegExp["$1"]); if (fIEVersion == 7) { return "IE7"; } else if (fIEVersion == 8) { return "IE8"; } else if (fIEVersion == 9) { return "IE9"; } else if (fIEVersion == 10) { return "IE10"; } else if (fIEVersion == 11) { return "IE11"; } else { return "0"; }//IE版本过低 return "IE"; } if (isOpera) { return "Opera"; } if (isEdge) { return "Edge"; } if (isFF) { return "FF"; } if (isSafari) { return "Safari"; } if (isChrome) { return "Chrome"; }}
