官方示例

1、只對于數(shù)據(jù)層面來說。不涉及html和css。
2、通過Vue.component方法聲明。

var EmptyList = { /* ... */ }
var TableList = { /* ... */ }
var OrderedList = { /* ... */ }
var UnorderedList = { /* ... */ }

Vue.component('smart-list', {
  functional: true,
  props: {
    items: {
      type: Array,
      required: true
    },
    isOrdered: Boolean
  },
  render: function (createElement, context) {
    function appropriateListComponent () {
      var items = context.props.items

      if (items.length === 0)           return EmptyList
      if (typeof items[0] === 'object') return TableList
      if (context.props.isOrdered)      return OrderedList

      return UnorderedList
    }

    return createElement(
      appropriateListComponent(),
      context.data,
      context.children
    )
  }
})
