HarmonyOS 一个页面里，怎么引用两种自定义弹出框？

Question

我的弹出框样式差别比较大，所以我需要写两个弹出框，但是自定义的弹出框要怎么引入两个呢？

以下是我引入了一个了

// 调用弹框
dialogController: CustomDialogController | null = new CustomDialogController({
  builder: DeviceOpenDialog({
    IsDeviceSuccess:$IsDeviceSuccess,
    confirm: ()=> { }
  }),
  autoCancel: false,
  alignment: DialogAlignment.Center,
  gridCount: 8,
  customStyle: false,
  cornerRadius: 10,
})

// 在自定义组件即将析构销毁时将dialogControlle置空
aboutToDisappear() {
  this.dialogController = null
}

// wifi设置
setWIFI () {
  if (this.dialogController != null) {
    this.dialogController.open()
  }
}

请参考以下代码，支持文档：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/ts-methods-custom-dialog-box-V5

// xxx.ets
@CustomDialog
struct CustomDialogExampleTwo {
  controllerTwo?: CustomDialogController
  build() {
    Column() {
      Text('我是第二个弹窗')
        .fontSize(30)
        .height(100)
      Button('点我关闭第二个弹窗')
        .onClick(() => {
          if (this.controllerTwo != undefined) {
            this.controllerTwo.close()
          }
        })
        .margin(20)
    }
  }
}
@CustomDialog
struct CustomDialogExample {
  @Link textValue: string
  @Link inputValue: string
  dialogControllerTwo: CustomDialogController | null = new CustomDialogController({
    builder: CustomDialogExampleTwo(),
    alignment: DialogAlignment.Bottom,
    offset: { dx: 0, dy: -25 } })
  controller?: CustomDialogController
  // 若尝试在CustomDialog中传入多个其他的Controller，以实现在CustomDialog中打开另一个或另一些CustomDialog，那么此处需要将指向自己的controller放在所有controller的后面
  cancel: () => void = () => {
  }
  confirm: () => void = () => {
  }

  build() {
    Column() {
      Text('Change text').fontSize(20).margin({ top: 10, bottom: 10 })
      TextInput({ placeholder: '', text: this.textValue }).height(60).width('90%')
        .onChange((value: string) => {
          this.textValue = value
        })
      Text('Whether to change a text?').fontSize(16).margin({ bottom: 10 })
      Flex({ justifyContent: FlexAlign.SpaceAround }) {
        Button('cancel')
          .onClick(() => {
            if (this.controller != undefined) {
              this.controller.close()
              this.cancel()
            }
          }).backgroundColor(0xffffff).fontColor(Color.Black)
        Button('confirm')
          .onClick(() => {
            if (this.controller != undefined) {
              this.inputValue = this.textValue
              this.controller.close()
              this.confirm()
            }
          }).backgroundColor(0xffffff).fontColor(Color.Red)
      }.margin({ bottom: 10 })

      Button('点我打开第二个弹窗')
        .onClick(() => {
          if (this.dialogControllerTwo != null) {
            this.dialogControllerTwo.open()
          }
        })
        .margin(20)
    }.borderRadius(10)
    // 如果需要使用border属性或cornerRadius属性，请和borderRadius属性一起使用。
  }
}
@Entry
@Component
struct CustomDialogUser {
  @State textValue: string = ''
  @State inputValue: string = 'click me'
  dialogController: CustomDialogController | null = new CustomDialogController({
    builder: CustomDialogExample({
      cancel: ()=> { this.onCancel() },
      confirm: ()=> { this.onAccept() },
      textValue: $textValue,
      inputValue: $inputValue
    }),
    cancel: this.exitApp,
    autoCancel: true,
    alignment: DialogAlignment.Bottom,
    offset: { dx: 0, dy: -20 },
    gridCount: 4,
    customStyle: false,
    cornerRadius: 10,
  })

  // 在自定义组件即将析构销毁时将dialogControlle置空
  aboutToDisappear() {
    this.dialogController = null // 将dialogController置空
  }

  onCancel() {
    console.info('Callback when the first button is clicked')
  }

  onAccept() {
    console.info('Callback when the second button is clicked')
  }

  exitApp() {
    console.info('Click the callback in the blank area')
  }
  build() {
    Column() {
      Button(this.inputValue)
        .onClick(() => {
          if (this.dialogController != null) {
            this.dialogController.open()
          }
        }).backgroundColor(0x317aff)
    }.width('100%').margin({ top: 5 })
  }
}

或者

@CustomDialog
struct MyDialog1 {
  controller2: CustomDialogController
  controller1: CustomDialogController
  title: string=''
  build() {
    Row() {
      Column({ space: 10 }) {
        Text(this.title)
          .fontSize(30)
          .fontColor(Color.Blue)
        Button('点击打开弹窗2')
          .onClick(() => {
            this.controller2.open()
          }).backgroundColor(0xffffff)
          .fontColor(Color.Red)
        Flex({ justifyContent: FlexAlign.SpaceAround }) {
          Button('cancel')
            .onClick(() => {
              this.controller1.close()
            }).backgroundColor(0xffffff).fontColor(Color.Black)
        }.width("100%")
      }.width("50%")
    }.height("50%")
  }
}
// 弹窗组件
@CustomDialog
struct MyDialog2 {
  controller: CustomDialogController
  title: string=''
  build() {
    Row() {
      Column({ space: 10 }) {
        Text(this.title)
          .fontSize(30)
          .fontColor(Color.Blue)
        Flex({ justifyContent: FlexAlign.SpaceAround }) {
          Button('cancel')
            .onClick(() => {
              this.controller.close()
            }).backgroundColor(0xffffff).fontColor(Color.Black)
          Button('confirm')
            .onClick(() => {
              this.controller.close()
            }).backgroundColor(0xffffff).fontColor(Color.Red)
        }.width("100%")
      }.margin({ bottom: 10 })
    }.height("50%")
  }
}
