<template>
  <div>
      <p @click='emit'>{{msg}}</p>
      <p @click='emitOther'>{{msg2}}</p>
  </div>
</template>

<script>
export default {
  name: 'demo',
  data () {
      return {
         msg : '点击后女人派发事件',
         msg2 : '点击后女人派发事件2',
      }
  },
  created () {

      this.$on(['wash_Goods','drive_Car'],(arg)=> {
          console.log('事真多')
      })
      this.$on('wash_Goods',(arg)=> {
          console.log(arg)
      })
      this.$on('drive_Car',(...arg)=> {
          console.log(BMW,Ferrari)
      })
  },
  methods : {
      emit () {
         this.$emit('wash_Goods','fish')
      },
      emitOther () {
         this.$emit('drive_Car',['BMW','Ferrari'])
      }
  }
}
