How to pass values between parent and child components in vue?

}

I defined two different components:



'permissionTitle':customTitle,
'permissionItem':customItem,


in main template they are organized like this:



    <permissionTitle content="品牌商管理">
<permissionItem>查看列表</permissionItem>
<permissionItem>添加</permissionItem>
<permissionItem>修改</permissionItem>
<permissionItem>删除</permissionItem>
</permissionTitle>


Now I want to pass values from permissionItem to permissionTitle and vice versa.
How to can I do this?



In permissionTitle.vue:



<template>
<div id="root">
<Checkbox>
<span>{{content}}</span>
</Checkbox>
<slot></slot>
</div>
</template>


In permissionItem.vue:



<template>
<Checkbox @on-change="change">
<slot></slot>
</Checkbox>
</template>

          You can do this with v-model.



          Add a model and prop to your child component, something like this:



          Vue.component('permissionItem', {
          model: {
          prop: 'value',
          event: 'change'
          },
          props: {
          value: String
          },
          methods: {
          // or however this value changes in your component
          changeValue(newValue) {
          this.value = value;
          $emit('change', this.value;
          ....


          And instantiate it like this:



          <permissionTitle content="品牌商管理">
          <permissionItem :v-model="value1">查看列表</permissionItem>
          <permissionItem :v-model="value2">添加</permissionItem>
          <permissionItem :v-model="value3">修改</permissionItem>
          <permissionItem :v-model="value4">删除</permissionItem>
          </permissionTitle>


          variables 'valueN' are now available in your parent component.



          Vue's documentation on this topic is a little lacking, but its basically here: https://vuejs.org/v2/guide/components-custom-events.html
