vue自定义插件(全局组件),以及向插件传值

1 编写子组件

load.vue内容

<template>
    <div>
        Load...
    </div>
</template>
<script></script>
<style>
</style>

Tree.vue内容:

<template>
	<div><h1>{{logo}}</h1><el-select
    v-model="value10"
    multiple
    filterable
    allow-create
    default-first-option
    placeholder="请选择文章标签">
    <el-option
      v-for="item in options5"
      :key="item.value"
      :label="item.label"
      :value="item.value">
    </el-option>
  </el-select></div>
  
  
</template>

<script>
  export default {
    data() {
      return {
        options5: [{
          value: 'HTML',
          label: 'HTML'
        }, {
          value: 'CSS',
          label: 'CSS'
        }, {
          value: 'JavaScript',
          label: 'JavaScript'
        }],
        value10: []
      }
    },
    created: function () {
       console.log("logo : " + this.logo); 
   },
    props: ['logo']
  }
</script>

index.js内容

import LoadComponent from './Load.vue';
import TreeComponent from './Tree.vue';

const Load={
    install:function (Vue) {
        Vue.component('Load',LoadComponent);
        Vue.component('Tree',TreeComponent);
    }
}
export default Load

2 在main.js中引入插件

3 在父组件中使用
