如何在 ReactJS 中使用 JQuery

发布于07月22日

I'm new to ReactJS. Previously I've used jQuery to set any animation or feature that I needed. But now I'm trying to use ReactJS and minimize the use of jQuery.

My Case is:

I'm trying to build an accordion with ReactJS.

<div class="accor">
   <div class="head">Head 1</div>
   <div class="body hide">Body 1</div>
</div>
<div class="accor">
   <div class="head">Head 1</div>
   <div class="body hide">Body 1</div>
</div>
<div class="accor">
   <div class="head">Head 1</div>
   <div class="body hide">Body 1</div>
</div>

using JQuery:

$('.accor > .head').on('click', function(){
   $('.accor > .body').slideUp();
   $(this).next().slideDown();
});

My Question:

我怎样才能用ReactJS做到这一点？

推荐答案

You should try and avoid jQuery in ReactJS. But if you really want to use it, you'd put it in componentDidMount() lifecycle function of the component.

例如

class App extends React.Component {
  componentDidMount() {
    // Jquery here $(...)...
  }

  // ...
}

Ideally, you'd want to create a reusable Accordion component. For this you could use Jquery, or just use plain javascript + CSS.

class Accordion extends React.Component {
  constructor() {
    super();
    this._handleClick = this._handleClick.bind(this);
  }

  componentDidMount() {
    this._handleClick();
  }

  _handleClick() {
    const acc = this._acc.children;
    for (let i = 0; i < acc.length; i++) {
      let a = acc[i];
      a.onclick = () => a.classList.toggle("active");
    }
  }

  render() {
    return (
      <div 
        ref={a => this._acc = a} 
        onClick={this._handleClick}>
        {this.props.children}
      </div>
    )
  }
}

Then you can use it in any component like so:

class App extends React.Component {
  render() {
    return (
      <div>
        <Accordion>
          <div className="accor">
            <div className="head">Head 1</div>
            <div className="body"></div>
          </div>
        </Accordion>
      </div>
    );
  }
}
