我有以下div项目。第一个播放视频，第二个播放引导警报。我想在视频上显示提醒。任何人都可以帮忙吗？

trait AbstractParent{
  def valueP: Int
}

trait Parent1 extends AbstractParent{
  val valueP = 1
}

trait Parent2 extends AbstractParent{
  val valueP = 2
}

abstract class Child1 {self: AbstractParent =>
  def value = self.valueP
}

abstract class Child2 {self: AbstractParent =>
  def value = self.valueP
}



//client code

val c11 = new Child1 with Parent1
val c21 = new Child2 with Parent1
val c12 = new Child1 with Parent2
val c22 = new Child2 with Parent2
