Element UI 省市区数据联动

1、安装组件依赖

npm install element-china-area-data -S      

2、目标页面中引入

import {
  provinceAndCityData,
  regionData,
  provinceAndCityDataPlus,
  regionDataPlus,
  CodeToText,
  TextToCode
} from "element-china-area-data";      

3、使用el-cascader标签

<div style="width:460px;">
  <el-cascader style="width:100%;" :options="options" 
  v-model="selectedOptions" @change="addressChoose"></el-cascader>
</div>      

4、data中定义元素

data(){
    return{
      // 省市区级联
      options: regionDataPlus,
      selectedOptions: [],
    }
}      

5、触发事件的函数方法

/**省市区三级联动 */
addressChoose(value) {
  console.log(
   "省市区：",
   CodeToText[value[0]],
   CodeToText[value[1]],
   CodeToText[value[2]]
  );
  this.form.province = CodeToText[value[0]];
  this.form.city = CodeToText[value[1]];
   this.form.area = CodeToText[value[2]];
},      

6、数据回显

// 省市区转换
let province = this.form.province;
let city = this.form.city;
let area = this.form.area;
let arg1 = TextToCode[province].code;
let arg2 = TextToCode[province][city].code;
let arg3 = TextToCode[province][city][area].code;
this.selectedOptions.push(arg1, arg2, arg3);
