HarmonyOS 弹窗onWillDismiss

当前的规格是这样的，弹框弹起后左滑/右滑事件就是控制弹框的关闭，而弹框的onWillDismiss需求就是为了拦截左滑/右滑等事件，可以查看onWillDismiss此属性的说明：

https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-promptaction-V5#basedialogoptions11可以通过onWillDismiss的回调来实现效果，参考示例：

onWillDismiss: (dismissDialogAction: DismissDialogAction) => {
  console.info("reason" + JSON.stringify(dismissDialogAction.reason))
  console.log("dialog onWillDismiss")
  if (dismissDialogAction.reason == DismissReason.PRESS_BACK) {
    // dismissDialogAction.dismiss()
    router.pushUrl({ url: "router/url" })
  }
  if (dismissDialogAction.reason == DismissReason.TOUCH_OUTSIDE) {
    dismissDialogAction.dismiss()
  }
}

以上代码即在左滑的时候不控制弹框关闭，去执行router路由方法。
