在JSX中反应foreach

西里米亚2020-03-13

我有一个要通过REACT输出的对象

question = {
    text: "Is this a good question?",
    answers: [
       "Yes",
       "No",
       "I don't know"
    ]
}

而我的react组件（已减少）是另一个组件

class QuestionSet extends Component {
render(){ 
    <div className="container">
       <h1>{this.props.question.text}</h1>
       {this.props.question.answers.forEach(answer => {     
           console.log("Entered");  //This does ifre                       
           <Answer answer={answer} />   //THIS DOES NOT WORK 
        })}
}

export default QuestionSet;

从上面的代码片段中可以看到，我正在尝试通过在props中使用数组Answers来插入组件Answer的数组，它确实令人陶醉，但没有输出到HTML中。

class QuestionSet extends Component { render(){ <div className="container"> <h1>{this.props.question.text}</h1> {this.props.question.answers.map((answer, i) => { console.log("Entered"); // Return the element. Also pass key return (<Answer key={i} answer={answer} />) })} } export default QuestionSet;
