我處于react的學(xué)習(xí)階段，我定義了一個(gè)帶有三元運(yùn)算符條件的，內(nèi)聯(lián)樣式的對(duì)象，但它根本無(wú)法正常工作！有人可以幫我如何實(shí)現(xiàn)這一目標(biāo)嗎import React from 'react';function Joke(props){    const styles = {    fontSize: "30px", display: props.question && props.answer ? "block" : "none", display: props.punchline ? "block" : "none", color: !props.question && "#888888"  }    return(        <div>    <p className="qus" style={styles}> {props.jokes.question} </p>     <p className="ans" style={styles}> {props.jokes.answer} </p>        <p className="punch" style={styles}> {props.jokes.punchline} </p>        </div>    )}export default Joke/*--------------------------------------------------------------------*/import React from 'react';import Joke from "./Joke"function App(){    return (        <div>        <Joke jokes={{            question:"who is the president",            answer:"Trump"}} />        <Joke jokes={{                 punchline: "hey look there is no question and answer here but there is no space been taken by those"}} />        <Joke  jokes={{            question:"what is 1+1",            answer:"11"}}/>          </div>        )}export default App在某些情況下，我正在發(fā)送帶有問(wèn)題和答案的對(duì)象，在某些情況下，我只是在發(fā)送緊急通知而不是提問(wèn)和答案，有人可以告訴我是否存在一種在對(duì)象內(nèi)部設(shè)置三元條件的方法，每當(dāng)我將props對(duì)象作為參數(shù)傳遞給Joke函數(shù)時(shí)，都會(huì)被應(yīng)用
