uniapp省市区街道四级联动

<uni-forms-item name="memberStreet" label="所属街道">	
	  <uni-easyinput type="text" @focus="toggleStreet('bottom')" :clearable="false" v-model="street" />
</uni-forms-item>

<uni-popup ref="popup" background-color="#fff">
	<ehPicker @conceal="confirmStreet"/>
</uni-popup>

import ehPicker from '@/components/erha-picker/erha-picker.vue'
components:{
	ehPicker
},
confirmStreet(param) {
	this.street = param.province + param.city + param.area + param.street
	this.$refs.popup.close()
},

其中ehPicker为HBuilderX插件市场中引入，实际使用中配合项目稍作修改
