显示/隐藏多个元素的过渡

Question

我正在尝试在一个网页上实现显示/隐藏功能。基本上，我的网站上有一个页面显示“ Jargon”及其定义。用户单击标题，然后应显示定义。

我尝试了2种不同的技术，一种有效，但是非常苛刻，没有过渡，基本上是开放的或封闭的：

    jQuery(function($){
        var acc = document.getElementsByClassName("jarg-container");
        var i;
  
        for (i = 0; i < acc.length; i++) {
          acc[i].onclick = function() {
            this.classList.toggle("active");
            var panel = this.nextElementSibling;
            if (panel.style.maxHeight){
              panel.style.maxHeight = null;
            } 
            else {
              panel.style.maxHeight = panel.scrollHeight + "px";
            }    
          }
        }
      }); 

    .jarg-container {
        background: gainsboro;
        box-shadow: 4px 5px 14px 1px black;
        height: 4.5em;
        width: 45% !important;
        margin: 0 2.5% 2em;
    }
    .jarg-container h2 {
        display: flex;
        align-items: center;
        justify-content: center;
        cursor: pointer;
    }
    .jarg-container .jargon-desc {
        height: 0;
        display: none;
    }
    .jarg-container.active .jargon-desc{
        height:100%;
        display:block;
    }
    .jarg-container.active {
        height: 100%;
    }
    .jarg-container h2::after {
        content: '\02795';
        font-size: 0.5em !important;
        right: 10%;
        position: absolute;
    }
    .jarg-container.active h2::after {
        content: "\2796";
    }

我喜欢的另一个，但是当一个打开时，它们都打开了：

    $('.jargon-header').on('click', function(){
        $('.jargon-desc').toggleClass('show');
    });

    .jargon-desc {
        height: 0px;
        opacity: 0;
        transition: all .75s ease;
    }
    .jargon-desc.show {
        opacity: 1;
        height: 100%;
    }
    .jarg-container {
        background: gainsboro;
        box-shadow: 4px 5px 14px 1px black;
        width: 45% !important;
        margin: 0 2.5% 2em;
        transition:all .75s ease;
    }
    .jarg-container h2 {
        display: flex;
        align-items: center;
        justify-content: center;

理想情况下，我想结合使用2 ...，其中所有元素都单独打开，并使用第二个代码使用的过渡效果...

将这两种方法结合在一起的任何帮助都会令人惊奇

Answer 1

要同时实现过渡和一次仅移动一个元素，可以使用this关键字。调用函数时，在这种情况下，点击侦听器内部的function()会将this绑定到该上下文。这样，您可以简单地使用$(this)来选择单击的元素。

这可能不是最详细的说明，因此here会提供有关该主题的更多信息。

$('.jargon-header').on('click', function() {
  // Use this to select the element that was clicked
  $(this)
  // Then just select the next description
  .next('.jargon-desc')
  // And toggle the class on that description
  .toggleClass('show');
});

.jargon-desc {
  height: 0px;
  opacity: 0;
  transition: all .75s ease;
}

.jargon-desc.show {
  opacity: 1;
  height: 100%;
}

.jarg-container {
  background: gainsboro;
  box-shadow: 4px 5px 14px 1px black;
  width: 45% !important;
  margin: 0 2.5% 2em;
  transition: all .75s ease;
}

.jarg-container h2 {
  display: flex;
  align-items: center;
  justify-content: center;
  cursor: pointer;
}

.jarg-container h2::after {
  content: '\02795';
  font-size: 0.5em !important;
  right: 10%;
  position: absolute;
}

.jarg-container.show h2::after {
  content: "\2796";
}
