代码

GetBrowserCore.js：

export default () => {
  var sBrowser = null
  var sUsrAg = window.navigator.userAgent
  // The order matters here, and this may report false positives for unlisted browsers.
  if (sUsrAg.indexOf('Firefox') > -1) {
    sBrowser = 'Mozilla Firefox'
    // 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:61.0) Gecko/20100101 Firefox/61.0'
  } else if (sUsrAg.indexOf('Opera') > -1 || sUsrAg.indexOf('OPR') > -1) {
    sBrowser = 'Opera'
    // 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.102 Safari/537.36 OPR/57.0.3098.106'
  } else if (sUsrAg.indexOf('Trident') > -1) {
    sBrowser = 'Microsoft Internet Explorer'
    // 'Mozilla/5.0 (Windows NT 10.0; WOW64; Trident/7.0; .NET4.0C; .NET4.0E; Zoom 3.6.0; wbx 1.0.0; rv:11.0) like Gecko'
  } else if (sUsrAg.indexOf('Edge') > -1) {
    sBrowser = 'Microsoft Edge'
    // 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36 Edge/16.16299'
  } else if (sUsrAg.indexOf('Chrome') > -1) {
    sBrowser = 'Google Chrome or Chromium'
    // 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/66.0.3359.181 Chrome/66.0.3359.181 Safari/537.36'
  } else if (sUsrAg.indexOf('Safari') > -1) {
    sBrowser = 'Apple Safari'
    // 'Mozilla/5.0 (iPhone; CPU iPhone OS 11_4 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/11.0 Mobile/15E148 Safari/604.1 980x1306'
  } else {
    sBrowser = 'unknown'
  }
  return sBrowser
}

使用

import GetBrowserCore from './GetBrowserCore.js'
// 浏览器判断与处理
var browserCore = GetBrowserCore()
console.log(browserCore)
