HarmonyOS鸿蒙Next中record的实现方式

HarmonyOS鸿蒙Next中record的实现方式 构造一个对象类型，其属性键为 “Keys” ，其属性值为 “Type”，可用于将一种类型的属性映射到另一种类型。示例如下：

interface RecordType { 
  age: number; 
  name: string; 
} 

type RecordName = string; 

let name1: RecordType = { name: 'name1', age: 5 }; 
let name2: RecordType = { name: 'name2', age: 10 }; 
let name3: RecordType = { name: 'name3', age: 15 }; 

let dataInfo: Record<RecordName, RecordType> = { 
  'data1': name1, 
  'data2': name2, 
  'data3': name3, 
}; 

@Entry 
@Component 
struct Index { 
  build() { 
    Row() { 
      Column() { 
        Button('use Record') 
          .onClick(() => { 
            // dataInfo: {"data1":{"name":"name1","age":5},"data2":{"name":"name2","age":10},"data3":{"name":"name3","age":15}} 
            console.log('dataInfo:', JSON.stringify(dataInfo)); 
          }) 
      }.width('100%') 
    }.height('100%') 
  } 
}
