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

1. provinceAndCityData是省市二级联动数据（不带“全部”选项）

3. provinceAndCityDataPlus是省市区三级联动数据（带“全部”选项）
4. regionDataPlus是省市区三级联动数据（带“全部”选项）
5. “全部"选项绑定的value是空字符串”"
6. CodeToText是个大对象，属性是区域码，属性值是汉字 用法例如：CodeToText[‘110000’]输出北京市
7. extToCode是个大对象，属性是汉字，属性值是区域码
   用法例如：TextToCode[‘北京市’].code输出110000,TextToCode[‘北京市’][‘市辖区’].code输出110100,TextToCode[‘北京市’][‘市辖区’][‘朝阳区’].code输出110105

 省市二级联动（不带“全部”选项）:

<template><div id="app"><el-cascadersize="large":options="options"v-model="selectedOptions"@change="handleChange"></el-cascader></div>
</template><script>import { provinceAndCityData } from 'element-china-area-data'export default {data () {return {options: provinceAndCityData,selectedOptions: []}},methods: {handleChange (value) {console.log(value)}}}
</script>

</template><script>import { provinceAndCityDataPlus } from 'element-china-area-data'export default {data () {return {options: provinceAndCityDataPlus,selectedOptions: []}},methods: {handleChange (value) {console.log(value)}}}
</script>

</script>

CodeToText的使用

getCodeToText(codeStr, codeArray) {if (null === codeStr && null === codeArray) {return null;} else if (null === codeArray) {codeArray = codeStr.split(",");}let area = "";switch (codeArray.length) {case 1:area += CodeToText[codeArray[0]];break;case 2:area += CodeToText[codeArray[0]] + "/" + CodeToText[codeArray[1]];break;case 3:area +=CodeToText[codeArray[0]] +"/" +CodeToText[codeArray[1]] +"/" +CodeToText[codeArray[2]];break;default:break;}return area;}

 CodeToText的使用报错解决

下载的时候默认下载最新版本的， 稳定版本5.0.2版本才可以

npm install element-china-area-data@5.0.2  -S
