我该如何做到这一点，以便在单击上面的行图像之前隐藏每个问题。我基本上想在这个表单中添加一个显示/隐藏 div。当每个问题都得到回答时，最后会弹出“下一步”按钮。如果用户决定改变主意并单击另一个答案或图像，那么一切都会重新隐藏并再次显示内容。我创建了一个单独的测试表单，它可以工作，但它可以按照我的意愿运行，所以现在我在这里。帮我。

首先，您的 html 中有很多错误。div 上有未闭合的标签、相同的 id、type 属性，但它应该在输入字段中。除此之外，我的想法是将每个问题包装在一个 div 中，并在需要时显示/隐藏它。这是代码：

var questions = $(".question");
var showQuestions = function(index) {
    for(var i=0; i<questions.length; i++) {
        if(i < index) {
            questions.eq(i).css("display", "block");
        } else {
            questions.eq(i).css("display", "none");
        }
    }    
}

for(var i=0; i<questions.length; i++) {
    (function(index) {
        questions.eq(index).find("div[type='radio']").on("click", function() {
            showQuestions(index+2);
        })
    })(i);
}
showQuestions(1);

这是您页面的完整代码。

var flag = false;
$(window).load(function(){
$('.radio div').on('click', function () {
 ...........
 ...........
 if(flag)
    resetQuestions();

 if (q1.length !== 0 && q2.length !== 0 && q3.length !== 0 && q4.length !== 0)
 {
      flag=true;
      .......... } ..............       
});});


function resetQuestions(){
   //your reset code
}
  • 当所有问题都已回答时设置一个标志
  • 每次单击 div 时都要检查该标志
  • 如果发现该标志已设置（即所有问题都已被回答），则调用重置函数
  • 在那个重置功能中重置问题
