getRuntimeEnv - 获取 JS 运行环境

使用

import { getRuntimeEnv } from 'iflyjs'
console.log(getRuntimeEnv()) // output: {isWeex: false, isIE: false, isIE9: false, isEdge: false, isAndroid: false, }

源码

function getRuntimeEnv() {
  const inBrowser = typeof window !== 'undefined'
  // @ts-ignore
  const inWeex = typeof window.WXEnvironment !== 'undefined' && !!window.WXEnvironment.platform
  // @ts-ignore
  const weexPlatform = inWeex && window.WXEnvironment.platform.toLowerCase()

  //浏览器 UA 判断
  const UA = inBrowser && window.navigator.userAgent.toLowerCase()
  const isIE = UA && /msie|trident/.test(UA)
  const isIE9 = UA && UA.indexOf('msie 9.0') > 0
  const isEdge = UA && UA.indexOf('edge/') > 0
  const isAndroid = (UA && UA.indexOf('android') > 0) || weexPlatform === 'android'
  const isIOS = (UA && /iphone|ipad|ipod|ios/.test(UA)) || weexPlatform === 'ios'
  const isChrome = UA && /chrome\/\d+/.test(UA) && !isEdge
  // 添加是否是Safari的判断
  const isSafari = UA && /safari/.test(UA) && !isChrome && !isAndroid
  return {
    isWeex: inWeex,
    isIE,
    isIE9,
    isEdge,
    isAndroid,
    isIOS,
    isChrome,
    isSafari
  }
