JavaScript noob在这里。我正在尝试制作一个我正在研究的测验应用程序，但我真的不知道如何继续。我用html写出了所有问题。
情况如下：此测验没有正确的答案，只是回答值。代码应该将每个问题的所有值相加，并根据累积的总点数在最后显示最终得分/描述：

<h1>What Type of Date Are You? (Dude Edition)</h1>
</div>
<div class="questions">
<p>1. You see a girl waiting at the bus stop. She is exactly your type. How do you get her number?</p>
<form class="options">
<input class="option" type="radio" name="question1" value=4>You walk right up to her, strike up a conversation, and ask for her number<br>
<input class="option" type="radio" name="question1" value=3>You wait a few days until you get the courage to go and talk to her<br>
<input class="option" type="radio" name="question1" value=2>You tell one of your mutual friends that you like her<br>
<input class="option" type="radio" name="question1" value=1>You wait for her to come to you</br>
</form>
</div>
<div class="questions">
<p>2. You guys decide to go out on a date. Where do you decide to take her?</p>
<form class="options">
<input class="option" type="radio" name="question2" value=4>You take her out for a short coffee and talk about life and relationships<br>
<input class="option" type="radio" name="question2" value=3>You take her out on a creative date and ask her questions about her life and you respond in kind, tried-and-true interview-style<br>
<input class="option" type="radio" name="question2" value=2>You take her out to a nice restaurant and dress in your best clothes. You ask the same questions as above<br>
<input class="option" type="radio" name="question2" value=1>You take her to the best restaurant and hope that your clothes does most of the talking. If not, you've got great stories to tell up your sleeves<br>
</form>
</div>
<div class="questions">
<p>3. You think you had a great first date. What do you do between now and your second date?</p>
<form class="options">
<input class="option" type="radio" name="question3" value=4>You send her a text telling her you'll have out again soon. No big deal. Another date with another girl, coming up!<br>
<input class="option" type="radio" name="question3" value=3>You send her a text telling her how much fun you had and can't wait for the next date.<br>
<input class="option" type="radio" name="question3" value=2>In addition to doing above, you call her and ask her how she thinks the date went and when/where the next date is<br>
<input class="option" type="radio" name="question3" value=1>In addition to doing above, you think about how lucky you are for finally finding an amazing girl. You hope to start a relationship ASAP<br>
</form>
</div>
<div class="questions">
<p>4. Crap! You just remembered you have a huge project due this Friday. This might be a problem. How many dates do you have this week?</p>
<form>
<input class="option" type="radio" name="question4" value=4>More than 5. You're going to have to cancel one of them.<br>
<input class="option" type="radio" name="question4" value=3>You have a few dates in the pipeline, just testing the waters. You can still make the dates<br>
<input class="option" type="radio" name="question4" value=2>You have one date because you're a one woman kind of guy<br>
<input class="option" type="radio" name="question4" value=1>You have one date. You don't date much, in general.<br>
</form>
</div>
<div class="questions">
<p>5. Finally, how spontaneous are you?</p>
<form>
<input class="option" type="radio" name="question5" value=4>YOLO is your middle name. Your amusement > all else<br>
<input class="option" type="radio" name="question5" value=3>You may not be the most wild or crazy person, but you are definitely down for good times<br>
<input class="option" type="radio" name="question5" value=2>You like to have fun as much as the next guy, as long as things don't get too out of hand<br>
<input class="option" type="radio" name="question5" value=1>I like to plan ahead, no matter what the situation, work or play<br>
</form>
</div>
<br>
<input type="button" id='next' value="Next" onlick="sum_values()">
这是我的JavaScript：
$(document).ready(function(){
answers = new Object();
$('.option').change(function(){
var answer = ($(this).attr('value'))
var question = ($(this).attr('name'))
answers[question] = answer
})
var item1 = document.getElementById('questions');
$('#next').click(function(){
var result = sum_values()
//do stuff with the result
alert(result);
});
})
function sum_values(){
var the_sum = 0;
for (questions in answers){
the_sum = the_sum + parseInt(answers[question])
}
return the_sum
}
$('#next').click(function(){
$('.questions').fadeOut();
$('.questions' + $(this).html()).delay(450).fadeIn();
我知道它充满了错误，但我希望尽可能多地学习，所以任何批评/帮助都会受到赞赏。我显然没有做到，所以我不会亲自接受。

欢迎使用Stackoverflow！当你走向死胡同时，SO会帮助你，但你必须竭尽全力并且真正陷入困境。关于javascript＆amp;网上有大量资源在线jQuery，谷歌是你的朋友:)
要回答“如何在javascript中一次出现一个测验问题”的问题，有一百种方法可以让一群紫色的火烈鸟出现。一种解决方案是获得问题的总量并跟踪当前显示的问题。然后，当用户点击下一个时，隐藏当前问题并显示下一个问题。http://jsfiddle.net/3kpFV/
//Store the total number of questions
var totalQuestions = $('.questions').size();
//Set the current question to display to 1
var currentQuestion = 0;
//Store the selector in a variable.
//It is good practice to prefix jQuery selector variables with a $
$questions = $('.questions');
//Hide all the questions
$questions.hide();
//Show the first question
$($questions.get(currentQuestion)).fadeIn();
//attach a click listener to the HTML element with the id of 'next'
$('#next').click(function () {
//fade out the current question,
//putting a function inside of fadeOut calls that function
//immediately after fadeOut is completed,
//this is for a smoother transition animation
$($questions.get(currentQuestion)).fadeOut(function () {
//increment the current question by one
currentQuestion = currentQuestion + 1;
//if there are no more questions do stuff
if (currentQuestion == totalQuestions) {
var result = sum_values()
//do stuff with the result
alert(result);
} else {
//otherwise show the next question
$($questions.get(currentQuestion)).fadeIn();
}
});
});
答案 1 :(得分：2)
奥尔曼教授的回答是一个非常有创意的答案。我正在寻找使用核心java脚本开发一些奇特的测验...但是... Slick Quiz - 这个jquery插件是我需要的东西。它干净，易于定制。
您只需要创建一个PHP脚本，以JSON格式公开您的所有测验数据。此插件默认支持许多配置。
答案 2 :(得分：-1)
#For the Next Prev Question or Survey Question to show and hide.#
<div class="question"></div>
<div class="d-flex justify-content-center ">
<div class="button hide col-md-2 btn btn-primary mt-5 btn-lg" id="next">Next</div>
<div class="button hide col-md-2 btn btn-primary btn-lg mt-5 ml-2" id="prev">Prev</div>
