新建一个js文件，我的命名是browserVersion.js

/* 判断各个浏览器版本号 */
function matchVesion() {let userAgent = navigator.userAgent;let rMsie = /(msie\s|trident.*rv:)([\w.]+)/;let rEdge = /(edg)\/([\w.]+)/;let rFirefox = /(firefox)\/([\w.]+)/;let rOpera = /(opera).+version\/([\w.]+)/;let rChrome = /(chrome)\/([\w.]+)/;let rSafari = /version\/([\w.]+).*(safari)/;let ua = userAgent.toLowerCase();var match = rMsie.exec(ua);if (match !== null) {return {browser: "IE",version: match[2] || "0"};}var rEmatch = rEdge.exec(ua);if (rEmatch !== null) {return {browser: 'Edge',version: rEmatch[2] || "0"};}var rFmatch = rFirefox.exec(ua);if (rFmatch !== null) {return {browser: rFmatch[1] || "",version: rFmatch[2] || "0"};}var rOmatch = rOpera.exec(ua);if (rOmatch !== null) {return {browser: rOmatch[1] || "",version: rOmatch[2] || "0"};}var rCmatch = rChrome.exec(ua);if (rCmatch !== null) {return {browser: rCmatch[1] || "",version: rCmatch[2] || "0"};}var rSmatch = rSafari.exec(ua);if (rSmatch !== null) {return {browser: rSmatch[2] || "",version: rSmatch[1] || "0"};}if (match !== null) {return {browser: "",version: "0"};}
}export default function initBrowserVersion() {let browserMatch = matchVesion();return browserMatch;
}

需要用到的地方引入这个js文件，直接调用就可以

import browserVersion from '../../base/utils/browserVersion';

结果：

edge浏览器匹配是edg不是edge！！！！搜了好多博客全是edge根本匹配不到这个浏览器好吗，我是用在埋点里的，其他功能自行导入这个js文件
