SwiftUI:当用户点击第一个ScrollView中的项目时，加载特定索引处的第二个ScrollView

struct ContentView: View {
    @State private var selectedItemIndex: Int? = nil
    let items = ["Item 1", "Item 2", "Item 3"]
    
    var body: some View {
        VStack {
            ScrollView {
                ForEach(0..<items.count) { index in
                    Button(action: {
                        selectedItemIndex = index
                    }) {
                        Text(items[index])
                    }
                }
            }
            
            if let index = selectedItemIndex {
                SecondScrollView(index: index)
            }
        }
    }
}

struct SecondScrollView: View {
    let index: Int
    let data: [String] = ["Data 1", "Data 2", "Data 3"]
    
    var body: some View {
        ScrollView {
            ForEach(0..<data.count) { dataIndex in
                Text(data[dataIndex])
            }
        }
    }
}
