Question

Understanding the user's preference for text alignment and managing how the text is displayed in a text area (or text field) within a ReactJS application

My latest project is an app that features multiple text areas. Personally, I use the app with two languages - English and another language that is aligned to the right. However, the default setting has the text-areas aligning to the left. To change this to align to the right, all it takes is a simple press of the right CTR+Shift keys. The app itself is built using React, but whenever the screen re-renders, it defaults back to aligning to the left. I am looking for a way to have control over the alignment - to be able to detect when a user chooses a specific alignment and save that choice to the state. How can I go about recognizing how the user wants to align their text, especially if they use right or left CTR+Shift commands? And most importantly, how can I adjust the text-area so that the alignment remains under the user's control?

Answer №1

let options = ['left', 'right', 'center'];

class ComponentExample extends React.component {
  constructor() {
    super();

    this.state = { alignment: 'left' };

    this.handleKeyPress = this.handleKeyPress.bind(this);
  }

  handleKeyPress(event) { // Detects key press and updates state
    if (event.shiftKey && (event.metaKey || event.ctrlKey)) { // Supports meta key for Macbook users
      this.setState({ alignment: 'right' });
    }
  }

  render() {
    return (
      <div className={styles.root}>
        <div style={{ textAlign: this.state.alignment }}> // Adjusts text alignment of the div
          <textarea onKeyPress={this.handleKeyPress} />
        </div>
      </div>
    );
  }
}
