我想用 react-hooks 制作一个点状进度指示器。 所以我有四个点表示进度。它从满到空，如果它是四个点，它是绿色的，三个黄色的，两个 - 红色的，一个是红色的。 我想控制用 Prop 点亮的点的颜色和数量，并用 react-hooks 来完成。
我能找到的唯一接近它的是codepen上的“Dotted progress bar”，但它仍然与我想要的不同。
我希望输出是，如果我通过 0-25%，它只会点亮一个红色点，50-75% 黄色点亮等等。
我已经尝试了一段时间了，我尝试过的最远的是:
const OnGoingRequest = ({ image, name, profession, progress, color }) => {
const [dotColor, setDotColor] = useState('#c4c4dd')
if (progress > 0 && progress <= 25) {
setDotColor('red')
} else if (progress > 25) {
setDotColor('blue')
}
return (

<UserProffession>{profession} </UserProffession>
</UserInfoContainer>
</UserContainer>
<ReviewStatusContainer>
<Box>
<Score />
<Bar>
<Progress progress={progress} color={dotColor} />
<Dot />
<Dot />
<Dot />
<Dot />
</Bar>
</Box>
<ReviewStatusReachout>REACHOUT AGAIN</ReviewStatusReachout>
</ReviewStatusContainer>
</EachReview>
)
}

progress 作为 props 传递，我正在根据它进行检查，但我得到了太多重新渲染的错误。估计是返回前检查的缘故。
最佳答案
我找到了解决方案。我收到 1、2、3 或 4 作为 Prop ，我正在根据它进行渲染。
