element地址三级联动

1. 首先引入相关组件
   import {regionData, CodeToText, TextToCode} from ‘element-china-area-data’

2. 使用组件

   <el-cascader
   size=“large”
   :options=“sendaddresss”
   v-model=“sendOptions”
   @change=“handleChanges” style=“width:217px;” clearable>
   

   data() {
     return {
    		 datas:[],
    	 	sendaddresss: regionData,
      		CodeToText,
       	TextToCode,
     		sendareas: '',//详细地址
         	sendOptions: [],
         	sendreturnprovince:'',
         	sendreturncity:'',
         	sendreturnregion:'',
     }
   },
   methods: {
   	//通过下拉列表选择获取省市区
   	handleChanges(value) {
          	 this.sendreturnprovince = CodeToText[this.sendOptions[0]]
      		 if (CodeToText[this.sendOptions[1]] == '市辖区') {
        			 this.sendreturncity = this.sendreturnprovince
       	} else {
         		this.sendreturncity = CodeToText[this.sendOptions[1]]
      		 }
       	this.sendreturnregion = CodeToText[this.sendOptions[2]]
    	 },
   	//通过省市区获取对应编码
    	 convertTextToCode(provinceText, cityText, regionText) {
   			let code = ''
   			if (provinceText && this.TextToCode[provinceText]) {
     				const province = this.TextToCode[provinceText]
     				code += province.code + ', '
    				 if (cityText && province[cityText]) {
       				const city = province[cityText]
       				code += city.code + ', '
      					 if (regionText && city[regionText]) {
         						code += city[regionText].code
       				}
    				 }
   			}
   			return code
   	},
   
   },
   mounted(){
   	//通过this.datas获取地址赋值到页面
   	this.sendOptions[0] = (this.TextToCode[this.datas.AddresserProvince].code)
   	if (this.datas.AddresserProvince != this.datas.AddresserCity) {
   		this.datas.AddresserCity = this.datas.AddresserCity
   	} else {
   	 this.datas.AddresserCity = '市辖区'
   	}
   	this.sendOptions[1] = (this.TextToCode[this.datas.AddresserProvince][this.datas.AddresserCity].code)
   
   this.sendOptions[2] = (this.TextToCode[this.datas.AddresserProvince][this.datas.AddresserCity][this.datas.AddresserRegion].code)
   
   
   this.sendOptions = [this.ruleForm.sendOptions[0], this.ruleForm.sendOptions[1], this.ruleForm.sendOptions[2]]
   }
