HarmonyOS 从want中取paramer如何判断其类型

可以通过instanceof来判断实体类型，参考示例：

@Entry
@Component
struct TestPage1 {
  @State list: Array<Object> = [new Cat(), new Dog()]

  build() {
    Row() {
      Column() {
        ForEach(this.list, (item: Object) => {
          if (item instanceof Cat) {
            Text("this is Cat")
          } else if (item instanceof Dog) {
            Text("this is Dog")
          }
        })
      }
      .width('100%')
    }
    .height('100%')
  }
}

class Cat {
}

class Dog {
}

// 判断布尔类型可以使用typeof，参考示例：
@Entry
@Component
struct TestPage1 {
  @State list: Array<Object> = [new Cat(), new Dog()]
  booleanParam: boolean = true
  build() {
    Row() {
      Column() {
        Button('判断布尔')
          .onClick(() => {
            console.log(typeof this.booleanParam)
          })
      }
      .width('100%')
    }
    .height('100%')
  }
}
