如何在Reactjs中使用类查找所有DOM元素？

Question

I'm creating a game right now using React and I need help with finding all elements with a certain className. This is a part of my code:

class FourthLine extends React.Component {
render() {
    const monsterList4 = [];
    for (let i = 0; i < 11; i++) {
        const monsterLine4 = <div className="four-line enemys"></div>
        monsterList4.push(monsterLine4)
    }
    return <div className="line-four">
        {monsterList4}
    </div>
   }
}

I want to get all elements with className "enemys" and read that enemys position x and position y. Is that even possible using React?

Answer 1

您可以使用document.getElementsByClassName('enemys')
