//注冊回調(diào)函數(shù)，第一次連接時調(diào)用 初始化函數(shù)(android需要初始化,ios不用)

        });
    }
};

main.js中引入:

import Bridge from './config/JSbridge.js'
Vue.prototype.$bridge = Bridge

組件中使用:
方法名和app開發(fā)人員溝通好，這里js調(diào)app，app提供的方法是dataToAndroid；app調(diào)js，js提供的方法是dataToJs

注冊方法
  mounted(){
    this.getAPPDate()
  },

js調(diào)app
  sendMsg(){
    let msg = this.msg
    this.$bridge.callHandler('dataToAndroid',msg,(res)=>{
      alert('獲取app響應(yīng)數(shù)據(jù):'+res)
      this.test = res
    })
  },

app調(diào)js
  getAPPDate(){
    this.$bridge.registerHandler('dataToJs', (data, responseCallback) => {
      alert('app主動調(diào)用js方法，傳入數(shù)據(jù):'+ data)
      responseCallback(data)
    })
  }
