通过一个ref React访问几个元素

Question

I wanna get access to multiple elements with using refs feature. Then after I could iterate through elements of this.tabs . Code below doesn't work, how fix it to make work? Solution, which I use now is document.querySelectorAll('tabs') , but it doesn't seems right for React.

 class Comp extends React.Component { constructor(props) { super(props); this.tabs = React.createRef(); } componentDidMount() { console.log(this.tabs); } render() { return ( <div> <span class="tab" ref={this.tabs}>One</span> <span class="tab" ref={this.tabs}>Two</span> <span class="tab" ref={this.tabs}>Three</span> </div> ); } } ReactDOM.render( <Comp />, document.getElementById('app') );

Answer 1

You're assigning refs incorrect way. Do it in the early beginning of render() method:

this.tabs = []

refs are going to be assigned via

<span className="tab" ref={(tab) => { this.tabs.push(tab) }}>One</span>

I hope you could call this.tabs this case!
