SwiftUI:点击NavigationLink时如何做额外的工作？

struct ContentView: View {
    @State private var isSelected = false
    
    var body: some View {
        NavigationView {
            VStack {
                NavigationLink(destination: DetailView(), isActive: $isSelected) {
                    Text("Go to DetailView")
                }
                
                Button(action: {
                    // 执行额外的工作
                    self.isSelected = true
                }) {
                    Text("Do Extra Work")
                }
            }
        }
    }
}

struct DetailView: View {
    var body: some View {
        Text("Detail View")
    }
}
