angular - 星云步进器 NbStepper selectedIndex 不起作用（可能与 Angular 生命周期相关）

问题描述

创建星云步进器后，我无法设置它的 selectedIndex。当我单击按钮时，我从模板中看到变量已更新，但步进器没有改变。

我认为问题在于步进器在模态中，所以我在 StackBlitz 上构建了一个 MWE（示例），但在这里可行！也许问题是从 http get JSON 获取选项卡的内容。

我尝试使用 setTimeOut、zone.run()、ChangeDetectorRef 等。但选项卡永远不会改变（事件永远不会触发？）。如何以编程方式设置可见选项卡？

根据我需要设置第二步或第三步的条件，一种解决方法是在需要时隐藏第二步，但在这种情况下，问题是 nbStepperNext 不考虑是否隐藏了步骤（https://github .com/akveo/nebular/issues/2372）

这是我的 package.json：
