VUE2 realizes linkage selection of secondary provinces and cities
Now I will share with you an example of VUE2 front-end implementation of static secondary province and city linkage selection. It has a very good reference value and I hope it will be helpful to everyone.
TIPs:
Used the element UI selector
It’s almost the same if you switch to a normal select.
The data does not include the South China Sea Islands, and it defaults to the whole country.
HTML：
<!--联动选择地区-->
<el-form-item label="选择地区：">
<el-select size="small" style="width: 100px"
v-model="selectProv"
placeholder="请选择省份"
v-on:change="getProv($event)">
<el-option
v-for="item in provs"
:label="item.label"
:value="item.value">
</el-option>
</el-select>
<el-select size="small" style="width: 100px"
v-if="selectProv!=''"
v-model="selectCity"
placeholder="请选择城市"
v-on:change="getCity($event)">
<el-option
v-for="item in citys"
:label="item.label"
:value="item.value">
</el-option>
</el-select>
</el-form-item>JS：
