vue项目里使用bus传值

import Vue from ‘vue‘
const Bus = new Vue()
export default Bus

import EventBus from ‘@/bus.js‘
Vue.use(EventBus)
Vue.prototype.$EventBus = EventBus

this.$EventBus.$emit(‘uploading‘,‘sure‘)

mounted() {
       this.$EventBus.$on(‘uploading‘, val=>{
       console.log(val)       //打印出来 val ：sure
     })
  }

 this.$EventBus.$emit(‘Click‘, {
        id: id,
        num:num
      })

 this.$EventBus.$on(‘Click‘, ({ id,num }) => {
       console.log(id,num)        
    })
