实现卡片刷新功能鸿蒙示例代码

updateCard(context?: Context, formId?: string) {
    if (!context) {
      context = EntryContext.getContext() as Context
    }
    if (!formId) {
      formId = this.getFormId(context)
    }

    console.log('formIdformId', formId)

    if (formId) {
      let pref = dataPreferences.getPreferencesSync(context, { name: CardManager.KEY_CARD_INFO })
      let cardInfo = pref.getSync(CardManager.KEY_CARD_INFO, {}) as FormDataClass
      console.log('cardInfo', cardInfo)
      let dataClass = new FormDataClass()
      dataClass.title = cardInfo.title
      dataClass.data = cardInfo.data
      formProvider.updateForm(formId, formBindingData.createFormBindingData(dataClass))
      this.saveCardId(context, formId)
    }
  }
