Question

我有一个SVG，在这里称为“ example.svg”，它是作为组件被调用并创建的，就像这样：

import { ReactComponent as Example } from './example.svg';
import styles from './index.module.css';

const ExampleImg = ({ ...otherProps }) => (
  <Example className={styles.image} {...otherProps} />
);

export default ExampleImg;

该组件在其他地方被调用-在myPage上说-像这样：

const myButton = <ExampleImg {...nextButtonProps} />;

我的问题是这样

我需要能够通过插入可以从SVG外部进行控制的道具来控制SVG的填充颜色。有问题的SVG：

</svg>

具体来说，.st4是需要插入道具的类，类似于{fill: {currentColor}}。

然后，当currentColor调用myPage来根据条件控制填充时，可以通过ExampleImg道具传递{{1}}。

老实说，我不知道如何解决这个问题，因此任何指导将不胜感激！

Answer 1

那么我是否正确理解该SVG将被重写为React组件？（除非有重要原因，否则我可能会这样做）。 CSS实际上具有color属性的currentColor键值，因此您可以从外部控制颜色，即：

.svg-container {
  color: black; // or whatever color really
}

.st4 {
  fill: currentColor;
}

Answer 2

我建议实际上将SVG放入您的代码中，并将其作为道具传递：

import { ReactComponent as Example } from './example.svg';
import styles from './index.module.css';

const ExampleImg = ({ ...otherProps }) => (
  <Example className={styles.image} {...otherProps}>
    <svg {...}>
      <style>{`
      .st1{${props.fill}} 
      `}
      </style>
    </svg>
  </Example>
);

export default ExampleImg;

React-能够通过道具控制SVG的填充颜色
