Question

我试图创建一个总共有6个字段集的表单，我隐藏了最后5个字段集，并使用jquery通过简单的Next和Previous按钮来显示每个单击的对象。但是我坚持使用jQuery

jquery似乎与我的表单匹配，但是当我单击按钮时，它无法访问下一个字段集。

<form action="index.html" method="post">
 <fieldset>
  <input type="radio" id="key_contact_6" value="key_contact_6" name="user_age"><label for="key_contact_6" class="light">Strong Agree</label>
  <input type="button" name="next" class="action-button" value="Next" />
 </fieldset>

 <fieldset>
  <input type="radio" id="key_contact_1" value="key_contact_1" name="user_age"><label for="key_contact_1" class="light">Extremely Dissatisfied</label>
  <input type="button" name="previous" class="action-button" value="Previous" />
  <input type="button" name="next" class="action-button" value="Next" />
</fieldset>
...
</form>

这是我的CSS字段集，用于隐藏第一个字段之外的所有字段集：

fieldset:not(:first-of-type){
    display: none;
}
fieldset {
  margin-bottom: 30px;
  border: none;
}

最后是jquery部分：


//jQuery time
var current_fs, next_fs, previous_fs; //fieldsets
var left, opacity, scale; //fieldset properties which we will animate
var animating; //flag to prevent quick multi-click glitches

$(".next").click(function(){
    if(animating) return false;
    animating = true;

    current_fs = $(this).parent();
    next_fs = $(this).parent().next();

    //activate next step on progressbar using the index of next_fs
    $("#progressbar li").eq($("fieldset").index(next_fs)).addClass("active");

    //show the next fieldset
    next_fs.show(); 
    //hide the current fieldset with style
    current_fs.animate({opacity: 0}, {
        step: function(now, mx) {
            //as the opacity of current_fs reduces to 0 - stored in "now"
            //1. scale current_fs down to 80%
            scale = 1 - (1 - now) * 0.2;
            //2. bring next_fs from the right(50%)
            left = (now * 50)+"%";
            //3. increase opacity of next_fs to 1 as it moves in
            opacity = 1 - now;
            current_fs.css({
        'transform': 'scale('+scale+')',
        'position': 'absolute'
      });
            next_fs.css({'left': left, 'opacity': opacity});
        }, 
        duration: 800, 
        complete: function(){
            current_fs.hide();
            animating = false;
        }, 
        //this comes from the custom easing plugin
        easing: 'easeInOutBack'
    });
});

$(".previous").click(function(){
    if(animating) return false;
    animating = true;

    current_fs = $(this).parent();
    previous_fs = $(this).parent().prev();

    //de-activate current step on progressbar
    $("#progressbar li").eq($("fieldset").index(current_fs)).removeClass("active");

    //show the previous fieldset
    previous_fs.show(); 
    //hide the current fieldset with style
    current_fs.animate({opacity: 0}, {
        step: function(now, mx) {
            //as the opacity of current_fs reduces to 0 - stored in "now"
            //1. scale previous_fs from 80% to 100%
            scale = 0.8 + (1 - now) * 0.2;
            //2. take current_fs to the right(50%) - from 0%
            left = ((1-now) * 50)+"%";
            //3. increase opacity of previous_fs to 1 as it moves in
            opacity = 1 - now;
            current_fs.css({'left': left});
            previous_fs.css({'transform': 'scale('+scale+')', 'opacity': opacity});
        }, 
        duration: 800, 
        complete: function(){
            current_fs.hide();
            animating = false;
        }, 
        //this comes from the custom easing plugin
        easing: 'easeInOutBack'
    });
});

$(".submit").click(function(){
    return false;
})

我希望输出类似于此链接https://codepen.io/Creative_Srijon/pen/EKwRgO

我不需要那样的奇特效果，但至少他们可以继续进行下一个字段集并完美隐藏当前字段。

有人请帮助谢谢
