一、Element UI 中国省市区级联数据
本文参考:element-china-area-data - npm
1. 安装
npm install element-china-area-data -S
2. 使用
import { provinceAndCityData, regionData, provinceAndCityDataPlus, regionDataPlus, CodeToText, TextToCode } from 'element-china-area-data'
- provinceAndCityData是省市二级联动数据(不带“全部”选项)
- regionData是省市区三级联动数据(不带“全部”选项)
- provinceAndCityDataPlus是省市区三级联动数据(带“全部”选项)
- regionDataPlus是省市区三级联动数据(带“全部”选项)
- “全部"选项绑定的value是空字符串”"
- 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
- 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
3.案例
3.1 省市二级联动(不带“全部”选项):
<template>
<div id="app">
<el-cascader
size="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>
3.2 省市二级联动(带“全部”选项):
<template>
<div id="app">
<el-cascader
size="large"
:options="options"
v-model="selectedOptions"
@change="handleChange">
</el-cascader>
</div>
</template>
<script>
import { provinceAndCityDataPlus } from 'element-china-area-data'
export default {
data () {
return {
options: provinceAndCityDataPlus,
selectedOptions: []
}
},
methods: {
handleChange (value) {
console.log(value)
}
}
}
</script>
3.3 省市三级联动(不带“全部”选项):
<template>
<div id="app">
<el-cascader
size="large"
:options="options"
v-model="selectedOptions"
@change="handleChange">
</el-cascader>
</div>
</template>
<script>
import { regionData } from 'element-china-area-data'
export default {
data () {
return {
options: regionData,
selectedOptions: []
}
},
methods: {
handleChange (value) {
console.log(value)
}
}
}
</script>
3.4 省市三级联动(带“全部”选项):文章来源:https://www.toymoban.com/news/detail-604357.html
<template>
<div id="app">
<el-cascader
size="large"
:options="options"
v-model="selectedOptions"
@change="handleChange">
</el-cascader>
</div>
</template>
<script>
import { regionDataPlus } from 'element-china-area-data'
export default {
data () {
return {
options: regionDataPlus,
selectedOptions: []
}
},
methods: {
handleChange (value) {
console.log(value)
}
}
}
</script>
二、CodeToText的使用
把区域码转成汉字文章来源地址https://www.toymoban.com/news/detail-604357.html
getCodeToText(codeArray) {
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;
}
console.log(area);
}
