使用React(JS)中的事件处理程序与SVG标记元素交互

import React from 'react';

class MyComponent extends React.Component {
  render() {
    return (
      <svg>
        {/* SVG标记元素 */}
      </svg>
    );
  }
}

export default MyComponent;

import React from 'react';

class MyComponent extends React.Component {
  handleClick() {
    // 处理点击事件的代码
  }

  render() {
    return (
      <svg>
        <circle onClick={this.handleClick} cx="50" cy="50" r="40" />
      </svg>
    );
  }
}

export default MyComponent;

import React from 'react';

class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      clicked: false
    };
  }

  handleClick() {
    this.setState({ clicked: true });
  }

  render() {
    const { clicked } = this.state;

    return (
      <svg>
        <circle
          onClick={this.handleClick.bind(this)}
          cx="50"
          cy="50"
          r="40"
          fill={clicked ? 'red' : 'blue'}
        />
      </svg>
    );
  }
}

export default MyComponent;
