vue子组件与子组件之前传值-----最简单办法

1.在main.js中定义一个值（红色为重点）

new Vue({
  el: '#app',
  data: {
    Bus: new Vue()
  },
  router,
  store,
  render: h => h(App)
})

2.在components/EditOrder.vue组件中点击按钮传值

<template>
      <div class="analysis"
               @click="analysis">点击</div> 
</template>
<script>
  export default {
    methods: {
        analysis() {
          this.$root.Bus.$emit('analysisClick', true)
        }
    }
  }
</script>

3.components/analysisAddress.vue中接收EditOrder组件传值

<script>
    export default {
      mounted() {
        const that = this
        this.$root.Bus.$on('analysisClick', function (msg) {
          that.addressAnalysis = msg
        })
    }
</script>

好啦，大功告成，是不是很简单的样子
