基于vue3和element-plus的省市区级联组件

<template>
  <div class="app">
    <!--默认使用-->
    <elui-china-area-dht @change="onChange"></elui-china-area-dht>
    <!--带isall参数和leave参数示例-->
    <elui-china-area-dht isall :leave="2" @change="onChange"></elui-china-area-dht>
  </div>
</template>

<script>
import { defineComponent } from 'vue'
import { EluiChinaAreaDht } from 'elui-china-area-dht'
const chinaData = new EluiChinaAreaDht.ChinaArea().chinaAreaflat
export default defineComponent({
    components: {
        EluiChinaAreaDht,
    },
    setup() {
        function onChange(e) {
          const one = chinaData[e[0]]
          const two = chinaData[e[1]]
          console.log(one, two)
        }
        return {
            onChange,
        }
