我需要一些帮助来制作类似于 Accordion 的东西。目标是，如果您单击导航中的链接，一个部分会消失，而您单击的部分会出现(在相同位置且不明显)。
如果可能，它还应该自动滚动到该部分的开头(导航的结尾)。
任何建议或起点？
JSFiddle

$(function() {
  var shrinkHeader = 50;
  $(window).scroll(function() {
    var scroll = getCurrentScroll();
    if (scroll >= shrinkHeader) {
      $('#navbar').addClass('shrink');
    } else {
      $('#navbar').removeClass('shrink');
    }
  });

  function getCurrentScroll() {
    return window.pageYOffset || document.documentElement.scrollTop;
  }
});

  margin: 0;
  padding: 0;
  font-family: helvetica;
}

body {
  height: 300vh;

h1 {
  text-align: center;
  font-size: 5rem;

最佳答案

希望这是有帮助的。我花了几个小时才把它拉下来。甚至在 stackoverflow 上搜索

 <!DOCTYPE html>
 <html>
 <title>Menu animation using javascript</title>
 <meta name="viewport" content="width=device-width, initial-scale=1">

 <style>
 #navi{
     position: absolute;
     top: 40px;
     left: 3%;
     width: 25%;
 }

 .menuItem{
     margin-bottom: 5px;
     width: 100%;
 }

 .menuPage{
     border: 1px solid #000000;
     background-color: #dcdcdc;
     text-align: center;
     padding: 2px 4px;
 }
 </style>

 <body>

 <div id="navi">

     <div id="Ldon" class="menuItem" onclick="openCity('London', 'Ldon')"><p class="menuPage">London</p>
         <div id="London" class="city" style="display:none">
             <h2>London</h2>
             <p>London is the capital city of England.</p>
         </div>
     </div>

     <div id="Pris" class="menuItem" onclick="openCity('Paris', 'Pris')"><p class="menuPage">Paris</p>
         <div id="Paris" class="city" style="display:none">
             <h2>Paris</h2>
             <p>Paris is the capital of France.</p> 
         </div>
     </div>

     <div id="Tkyo" class="menuItem" onclick="openCity('Tokyo', 'Tkyo')"><p class="menuPage">Tokyo</p>
         <div id="Tokyo" class="city" style="display:none">
             <h2>Tokyo</h2>
             <p>Tokyo is the capital of Japan.</p>
         </div>
     </div>

 </div>

 <script>
 function openCity(cityName, newPos) {
 var i;
 var y = document.getElementsByClassName("menuItem");
 var x = document.getElementsByClassName("city");
 var moevePos = document.getElementById(newPos);

 for (i = 0; i < y.length; i++) {
     y[i].style.position = "";  
     y[i].style.top = ""; 
 }

 for (i = 0; i < x.length; i++) {
     x[i].style.display = "none";  
 }

 document.getElementById(cityName).style.display = "block";  
 moevePos.style.position = "absolute";
 moevePos.style.top = "80px";
 }
 </script>

 </body>
 </html>
