如果给过来的不是地址的索引，而是地址呢

[vini123]

通常数据库中不会存 插件返回过来的索引。虽然，插件也会返回完整的地址。

假如数据库中存的用户地址是: 上海市-直辖市-徐汇区，初始化插件的时候，又该如何在 show 的时候就定位到这里呢。这个就是再次编辑的需要。而这里没有很好的提供到。我需要使用这个插件，又不能完全满足我的需要，就稍微改了一点。

在 props 中额为定义了一个 address 。使用 watch 监听它。在 引用页面对 address 进行赋值。比如我点击地址准备编辑的时候。一旦对 address 赋值，插件就会获取到，然后再调用插件里边的方法。新增的方法就可以。(VUE 我是新手，本来想找在引用页面调用插件里边的方法，没找到，只好出此下策)

watch: { address: function() { if (!this.address) return;

		let addressArr = this.address.split('-');
		let temp;
		
		if(addressArr.length >= 3) {
			temp = this.addressIndex(addressArr[0], addressArr[1], addressArr[2]);
		}
	  else if(addressArr.length == 2) {
			temp = this.addressIndex(addressArr[0], addressArr[1]);
		} else if(addressArr.length == 1) {
			temp = this.addressIndex(addressArr[0]);
		}
		
		this.pickerValueDefault = temp;
		this.initialize();
	}

},

methods:

addressIndex(province, city, area) { let provinceIndex, cityIndex, areaIndex = 0;

if(!province)
	return [provinceIndex, cityIndex, areaIndex];	 
		
for (var index in provinceData) {
	if (provinceData[index]['label'] == province) {
		provinceIndex = parseInt(index);
		break;
	}
}                                                         

if (!city)
	return [provinceIndex, 0, 0];
		
for (var index in cityData[provinceIndex]) {
	if (cityData[provinceIndex][index]['label'] == city) {
		cityIndex = parseInt(index);
		break;
	}
}

if(!area) 
	return [provinceIndex, cityIndex, 0];
		
for (var index in areaData[provinceIndex][cityIndex]) {
	if (areaData[provinceIndex][cityIndex][index]['label'] == area) {
		areaIndex = parseInt(index);
		break;
	}
}

return [provinceIndex, cityIndex, areaIndex];			

},

initialize () { this.handPickValueDefault(); this.provinceDataList = provinceData; this.cityDataList = cityData[this.pickerValueDefault[0]]; this.areaDataList = areaData[this.pickerValueDefault[0]][this.pickerValueDefault[1]]; this.pickerValue = this.pickerValueDefault; },
