页面中引入组件
import cityFormItem from '../components/citySelector'
components: {
cityFormItem
},
data:{
return {
areaData: {
province: '',
city: '',
district: ''
},
}
}
在template里面渲染
<cityFormItem
width="150"
label-width="100px"
provinceLabel="用户所在省份"
cityLabel="用户所在城市"
districtLabel="用户所在地区"
:province.sync="areaData.province"
:city.sync="areaData.city"
:district.sync="areaData.district">
</cityFormItem>
