#鸿蒙学习大百科#如何拦截Navigation路由？

this.pathStack.setInterception({
  willShow: (from: NavDestinationContext | NavBar, to: NavDestinationContext | NavBar,
    operation: NavigationOperation, isAnimated: boolean) => {
    // 页面跳转前拦截，允许操作栈，在当前跳转中生效。
  },
  didShow: (from: NavDestinationContext | NavBar, to: NavDestinationContext | NavBar,
    operation: NavigationOperation, isAnimated: boolean) => {
    //页面跳转后回调。在该回调中操作栈在下一次跳转中刷新，
  },
  modeChange: (mode: NavigationMode) => {
    //Navigation单双栏显示状态发生变更时触发该回调
  }
})
