不使用jQuery复制slideToggle效果

不使用jQuery复制slideToggle效果

3

由于Anki不支持jQuery，我该如何将这个特定文档上的jQuery转换为原生JS或仅使用CSS3来产生相同的效果（特别是关于+按钮和点击列表项时）？

$(document).ready(function () {
    $("#show-pronunciation").on("click", function () {
        $(".pronunciation").slideToggle();
    });
    $("li").on("click", function () {
        $(this).find("dl").slideToggle();
    });
});

body {

    background-color: #f7f7f7;
}

.definitions dl {
    border-left: 2px solid #ff1919;
    padding-left: 5px;    
}

dt {
    font-weight: bold;
}

dd {
    margin-left: 1em;
}

.main {
    margin: 20px 20px 0 20px;
    border: transparent;
    border-radius: 5px;
    /*padding: 15px 10px 5px 10px;*/
    border-collapse: collapse;
    background-color: #FF4C4C;
    padding-bottom: 5px;
}

.header {
    border-radius: 5px;
    padding: 5px;
    background-color: white;
}

.content {
    margin: 5px 5px 0px 5px;
    border: transparent;
    border-top: none;
    border-radius: 5px;
    padding: 5px;

你可以使用CSS过度实现此功能。例如：

.pronunciation, li dl {
  overflow: hidden;
  transition: height .3s linear;
}
.hidden {
  height: 0!important;
}

请看下面的代码（逻辑和你的一样，但是转换成了纯JavaScript和CSS3）：

document.addEventListener('DOMContentLoaded', function() {
  var show = document.getElementById('show-pronunciation');
  var pron = document.querySelector('.pronunciation');
  
  pron.style.height = pron.clientHeight + 'px';
  pron.classList.add('hidden');  
  show.addEventListener('click', function(e) {
    pron.classList.toggle('hidden');
  });
  
  [].forEach.call(document.querySelectorAll('li'), function(el, i) {
    var dl = el.querySelector('dl');
    dl.style.height = dl.clientHeight + 'px';
    
    el.addEventListener('click', function() {
      dl.classList.toggle('hidden');
    });
  });  
});
