Vue 组件

• $attrs：属性，会剔除 props 里的值
• $slots：组件插槽
• slotData：插槽传值
• entries：组件方法提取

<template>
  <vue-tree ref="elTree" v-bind="$attrs">
    <template v-for="(value, name) in $slots" #[name]="slotData">
      <slot :name="name" v-bind="slotData || {}" />
    </template>
  </vue-tree>
</template>

<script>
  export default {
    name: 'ModelTreeData',
    data() {
      return {}
    },
    mounted() {
      const entries = Object.entries(this.$refs['elTree'])
      for (const [key, value] of entries) {
        this[key] = value
      }
    }
  }
</script>
