  methods: {
   
   onAddressChange(picker, values) {
    let sheng = Object.keys(s);
    let shi = Object.keys(s[values[0]]);

　　　　　　let index=shi.indexOf(values[1])
　　　　　　let xian = s[values[0]][shi[index]];
　　　　　this.xianObj = xian;
    picker.setSlotValues(1, shi);
    this.addressProvince = values[0];
    this.addressCity = values[1];
    this.addressXian = values[2];
    picker.setSlotValues(2, Object.keys(xian));
   },
   onStreetChange(picker, values){
    this.addressStreet = values[0]
   },
  
  
  },
  watch: {
   &#39;addressXian&#39;: {
    handler(val, oval){
     let street = this.xianObj[this.addressXian]
     this.streetSlots[0].values = street
    }
   }
  },
  created(){
   
  },
  mounted(){
   this.$nextTick(() => {
    setTimeout(() => {//这个是一个初始化默认值的一个技巧
     this.addressSlots[0].defaultIndex = 0;
    }, 100);
   });

 }
