单击卡片时，进度条必须随着 useEffect 前进。我怎样才能做到这一点？

Question

我希望当我使用 useEffect 点击三张卡片中的一张时，进度条会前进，以便它有动画。我能怎么做？这样写会让我在 Hook 规则上出错。如果有另一种不使用 useEffect 的方法就好了，重要的是有动画，当我按下卡片时你会推进进度条（并且另一个 div 出现，但已经实现了）。

我正在使用 Bootstrap 进度条和 React。

提前致谢！

没有 useEffect 和 jquery 也可以做到。您有 RegisterChoiceClicked 用于在点击时推进进度条。然后你可以创建像 const [click, setClick] = useState(false) 这样的布尔变量，以便通过条件使用 DOM 进行操作。参见 example

单击卡片时，进度条必须随着 useEffect 前进。我怎样才能做到这一点？

When card is clicked, progress bar have to advance with useEffect. How can i do this?
