						//地址格式（省-市）
						const province = item.address.substring(0, item.address.indexOf('省') + 1);
						const city = item.address.substring(province.length, item.address.indexOf('市') +
						1);
					
						const districtIndex = item.address.indexOf(city) + city.length;
						const area = item.address.substring(districtIndex, item.address.indexOf('区') + 1);
						if(item.address.indexOf('市')!=-1){
							if(item.address.indexOf('区')!=-1){
								item.address = city + '-' + area
							}else{
