如何动态更改react-leaflet中Circle组件的颜色属性？

Question

我是反应传单的新手。所以在下面的代码中，我没有找到问题出在哪里。为什么color和fillColor属性没有在React-leaflet 的<Circle />组件中更新。但是当我执行console.log(casesTypeColors[casesType].hex)时，当caseType更改时，该值正在更新，但它没有反映在屏幕上。但其他属性正在更新。所以，请帮助我了解我在哪里做错了。提前致谢。

import { Circle } from "react-leaflet";
const casesTypeColors = {
  cases: {
    hex: "#CC1034",
    rgb: "rgb(204, 16, 52)",
    half_op: "rgba(204, 16, 52, 0.5)",
    multiplier: 800,
  },
  recovered: {
    hex: "#7dd71d",
    rgb: "rgb(125, 215, 29)",
    half_op: "rgba(125, 215, 29, 0.5)",
    multiplier: 1200,
  },
  deaths: {
    hex: "#fb4443",
    rgb: "rgb(251, 68, 67)",
    half_op: "rgba(251, 68, 67, 0.5)",
    multiplier: 2000,
  },
};
// Draw circles on the map with interactive tooptip
export const showDataOnMap = (data, casesType = "cases") =>
  data.map((country, index) => (
    <Circle
      key={index}
      center={[country.countryInfo.lat, country.countryInfo.long]}
      fillOpacity={0.4}
      color={casesTypeColors[casesType].hex}
      fillColor={casesTypeColors[casesType].hex}
      radius={
        Math.sqrt(country[casesType] / 10) *
        casesTypeColors[casesType].multiplier
       }
    >
    </Circle>
  ));

Answer 1

在showDataOnMap函数中写入：

<Circle pathOptions={{color: casesTypeColors[casesType].hex,
                     fillColor: casesTypeColors[casesType].hex }}>

代替

<Circle color={casesTypeColors[casesType].hex}
      fillColor={casesTypeColors[casesType].hex}>
