如何使用 Jquery 保存测验进度

Question

你好吗？

我正在做一个测验，我正在尝试听取用户的事件并保存它以便稍后根据 JSON 文件显示它们。

看，每题是：

{
    "question": "How much is two plus two?",
    "option1": "Four",
    "option2": "Five",
    "option3": "Two",
    "feedback": "Good"
}

"feedback"，我想保存并仅在测验结束时显示给用户。

基本上就是把他们的正确答案保存在后面，然后在最后显示"feedback" JSON变量

//i'm retrieving the value here, but what should I do with it?
var show = document.getElementById(this.id).innerHTML;

//and appending the values on the words

Check my fiddle

这里是JS

$(document).ready(function() {

 var questionNumber = 0;
 var wordNumber = 0;
 var questionBank = new Array();
 var wordsBank = new Array();
 var stage = "#game1";
 var stage2 = new Object;
 var questionLock = false;
 var numberOfQuestions;
 var score = 0;

 var data = {
     "quizlist": [

         {

你愿意帮我吗？

抱歉缩进不好，我正在努力写得更好！

谢谢！

完全忘记了 displayFinalSlide()。抱歉

一种方法是创建一个用户答案数组，并在我们确定他们的答案是对还是错后将一个新对象推入其中。您没有在 fiddle 中包含 displayFinalSlide() 的逻辑，因此我删除了该调用并将数组记录到控制台以便您可以看到它。

$(document).ready(function() {

              var questionNumber = 0;
              var wordNumber = 0;
              var questionBank = new Array();
              var wordsBank = new Array();
              var stage = "#game1";
              var stage2 = new Object;
              var questionLock = false;
              var numberOfQuestions;
              var score = 0;

              var feedbackBank = new Array();

              var data = {
                "quizlist": [

                  {
                    "question": "How much is two plus two?",
                    "option1": "Four",
                    "option2": "Five",
                    "option3": "Two",
                    "feedback": "Good"
                  }, {
                    "question": "Selecione a sentença correta",
                    "option1": "I am a person",

Answer 2

最简单的方法是用 jQuery $("#words").hide() 隐藏#words ，并在用 $("#words").show() 回答所有问题后显示它您没有定义函数 displayFinalSlide，所以现在您可以定义它并在最终幻灯片放映中显示用户反馈，就像我们说的：

function displayFinalSlide(){
 $("#words").show()
 $(stage).append('<div class="questionText">You have finished the quiz!<br><br>Total questions: '+numberOfQuestions+'<br>Correct answers: '+score+'</div>');

}
