Vue 全局组件传递参数

1.在components文件下创建相关组件如（breadcrumb.vue）

<template>
  <div>
    <el-breadcrumb separator-class="el-icon-arrow-right">
      <el-breadcrumb-item :to="{ path: '/home' }">首页</el-breadcrumb-item>
      <el-breadcrumb-item>{{breadName}}</el-breadcrumb-item>
      <el-breadcrumb-item>{{breadValue}}</el-breadcrumb-item>
    </el-breadcrumb>
  </div>

</template>

<script>
export default {
  name: 'breadcrumb',
  props: {
    breadName: {
      // 规定传值为字符串 默认的名字
      type: String,
      default: '默认的name'
    },
    breadValue: {
      type: String,
      default: '默认的value'
    }
  }
}
</script>

<style scoped>

</style>

2.main文件 全局注册

import Bread from './components/breadcrumb/breadcrumb.vue'
Vue.component('Bread', Bread)

3.使用全局组件

<template>
<div>
  <!--    面包屑东导区域-->
 <Bread :breadName="'999'" :breadValue="'666'"></Bread>

</div>
</template>

<script>
export default {
  name: 'Rights'
}
</script>

<style scoped>

</style>
