How to force a refresh of the current page in React?

In React, the forceUpdate() method can be used to forcefully refresh the current page. However, it is recommended to avoid using this method as it goes against React’s design principles.

Under normal circumstances, React will automatically update the page based on changes in the component’s state and props. React will re-render the page when there are changes in the component’s state or props to display the latest data.

If you are certain that you need to force refresh the current page, you can call the forceUpdate() method in the component. Here is an example:

import React, { Component } from 'react';
class MyComponent extends Component {
  handleClick = () => {
    // 执行一些操作后，调用 forceUpdate() 方法
    this.forceUpdate();
  };
  render() {
    return (
      <div>
        <button onClick={this.handleClick}>强制刷新</button>
      </div>
    );
  }
}

In the above example code, clicking the “Force Refresh” button will execute the handleClick() method and call the forceUpdate() method to forcibly refresh the current page.

Please note that forcing a refresh may lead to performance issues and goes against React’s design philosophy. It is generally recommended to prioritize triggering a page re-render by updating a component’s state or props, rather than using the forceUpdate() method.
