我正在制作“下一步”按鈕以移至此游戲中的下一張抽認(rèn)卡，但是當(dāng)我單擊該按鈕時(shí)，什么也沒有發(fā)生。我不知道我做錯(cuò)了什么。我在這段代碼中使用了很多變量，例如數(shù)字變量來說明它是哪個(gè)問題和答案。我嘗試每次向 number 變量添加一個(gè)，以將其更改為下一個(gè)問題，但它不起作用。    <div id="flashcard" onclick="flip()"><h1 id="word"></h1></div><br><button onlick="next()">Next</button><script>var questions;questions = ['artistic','daring','good','sports-minded','messy','disorganized','studious','funny','impacient','intelligent','neat','patient','lazy','shy','serious','nice','sociable','talented','hardworking','boy','girl','male friend','female friend','I','he','she','very','according to my family'];var answers = ['artístico, artística','atrevido','bueno, buena','deportista','desordenado, desordenada','estudioso, estudiosa','gracioso, graciosa','impaciente','intelligente','ordenado, ordenada','paciente','perezoso, perezosa','reservado, reservada','serio, seria','simpático, simpática','sociable','talentoso, talentosa','trabajador, trabajadora','el chico','la chica','el amigo','la amiga','yo','él','ella','muy','según mi familia'];var number = 0;var answer = answers[number];var word = questions[number];var display = document.getElementById('word');display.innerHTML = word;function flip(){if(word == questions[0]){display.innerHTML = answer;}if (word == questions[1]){display.innerHTML = answer;}if (word == questions[2]){display.innerHTML = answer;}if (word == questions[3]){display.innerHTML = answer;}if (word == questions[4]){display.innerHTML = answer;}if (word == questions[5]){display.innerHTML = answer;}if (word == questions[6]){display.innerHTML = answer;}if (word == questions[7]){display.innerHTML = answer;}if (word == questions[8]){display.innerHTML = answer;}if (word == questions[9]){display.innerHTML = answer;}if (word == questions[10]){display.innerHTML = answer;}if (word == questions[11]){display.innerHTML = answer;}if (word == questions[12]){display.innerHTML = answer;}if (word == questions[13]){display.innerHTML = answer;}我想要發(fā)生的是當(dāng)用戶單擊“下一步”按鈕時(shí)，它會(huì)更改為下一個(gè)閃存卡。
