使用typescript从react原生中的状态更新样式

import React, { useState } from 'react';

const MyComponent: React.FC = () => {
  const [style, setStyle] = useState({});

  // 根据需要更新样式的逻辑，调用setStyle方法更新状态中的样式对象

  return (
    <div style={style}>
      {/* 组件内容 */}
    </div>
  );
};

export default MyComponent;

import React, { useState, useEffect } from 'react';

const MyComponent: React.FC = () => {
  const [style, setStyle] = useState({});

  useEffect(() => {
    // 根据某个条件更新样式
    if (condition) {
      setStyle({ backgroundColor: 'red', color: 'white' });
    } else {
      setStyle({ backgroundColor: 'blue', color: 'black' });
    }
  }, [condition]);

  return (
    <div style={style}>
      {/* 组件内容 */}
    </div>
  );
};

export default MyComponent;

import React, { useState, useEffect } from 'react';

const MyComponent: React.FC = () => {
  const [style, setStyle] = useState({});

  useEffect(() => {
    // 根据某个条件更新样式
    if (condition) {
      setStyle({ backgroundColor: 'red', color: 'white' });
    } else {
      setStyle({ backgroundColor: 'blue', color: 'black' });
    }
  }, [condition]);

  return (
    <div style={style}>
      <h1>Hello, World!</h1>
    </div>
  );
};

export default MyComponent;
