使用mint-ui实现省市区三级联动效果的示例代码

export default {
 methods: {
 onValuesChange(picker, values) {
 if (values[0] > values[1]) {
 picker.setSlotValue(1, values[0]);
 }
 }
 },
 data() {
 return {
 slots: [
 {
  flex: 1,
  values: ['2015-01', '2015-02', '2015-03', '2015-04', '2015-05', '2015-06'],
  className: 'slot1',
  textAlign: 'right'
 }, {
  divider: true,
  content: '-',
  className: 'slot2'
 }, {
  flex: 1,
  values: ['2015-01', '2015-02', '2015-03', '2015-04', '2015-05', '2015-06'],
  className: 'slot3',
  textAlign: 'left'
 }
 ]
 };
 }
};

onProvinceChange(picker, values) {
   
   this.province = picker.getValues()[0]
   var cityArr = [];
   for(var key in provinceCity[this.province]) {
   cityArr.push(key);
   }
   this.slots2[0].values = cityArr;
  },
  onCityChange(picker, values) {
   this.city = picker.getValues()[0]
   var countyArr = [];
   for(var key in provinceCity[this.province][this.city]) {
   countyArr.push(key);
   }
   this.slots3[0].values = countyArr;
  },
  onCountyChange(picker, values) {
   
   this.county = picker.getValues()[0]
  },
