我有一个我想实现的身体系统功能。当用户将鼠标悬停在身体​​部位时，它会突出显示并显示该特定身体部位的信息。我已经按照我想要的方式对 CSS 进行了编码，但是我对 JavaScript 一无所知，以便在单击正文部分或鼠标离开悬停状态时获取信息。

我已经搜索了论坛并发现了类似的问题，并且花了几个小时试图从其他人的 javascript 解决方案中找出自己的问题 - 我正处于需要寻求帮助的地步。

这是我根据自己想要的效果制作的 Flash 原型：

如果您想看看我现在拥有的内容，这里是实时 HTML：

这是我的代码：

我认为以前的任何一个答案都不能完全满足您的要求。这是我的建议。请注意，CSS 已更改，最后添加了 javascript。

请注意，每个器官都被分配了一个绝对位置，在空间中具有不同的位置。如果您将所有这些都保持相同的左侧、顶部、宽度和高度，那么您将实现您所需要的。

您需要在彼此对应的链接和容器上创建一组简单的标识符。

JSFiddle：http: //jsfiddle.net/Y4Wtn

<style>
    .btn {font-weight:normal}
    .btn.active {font-weight:bold;}
    .pane {display:none;border:1px #ccc solid;padding:10px;}
    .pane.active {display:block;}
</style>
<script>
// insert jquery here
$(document).read(function(){

    $('.btn').click(function(){
        // grab the rel value of the the link that was clicked
        var thisRel = $(this).attr('rel');
        // remove active class from all .btn
        $('.btn').removeClass('active');
        // add active class to link that was clicked
        $(this).addClass('active');
        // remove all active classes from .pane
        $('.pane').removeClass('active');
        // add class active to pane with the same rel value clicked link
        $('.pane[rel="'+thisRel+'"]').addClass('active');         
    });

});
</script>
<ul>
    <li><a href="#1" class="btn active" rel="1">Item One</a></li>
    <li><a href="#2" class="btn" rel="2">Item Two</a></li>
    <li><a href="#3" class="btn" rel="3">Item Three</a></li>
</ul>

<div class="pane active" rel="1">Pane One</div>
<div class="pane" rel="2">Pane Two</div>
<div class="pane" rel="3">Pane Three</div>

您可以添加一个点击事件，查看我们点击的内容，然后在点击时永久更改样式。然后，这将永久“揭示”新零件。

您的 HTML：

<li id="lungs" onclick="highlight(this.id)">
   <!--some stuff-->
</li>

在 javascript 中（为简单起见，我将其放入<script>标签中，只需将此 + 您的其他案例添加到您的标题中）：

 <script> 
   function highlight(id) {
       var part = document.getElementById(id);
       switch(id){
          case "lungs":
             part.style.backgroundImage="url(excretory.png)";
             part.style.backgroundRepeat="no-repeat";
             part.style.backgroundPosition="-105px 523px";
             break;
          //rinse repeat for all cases, don't forget the : after your case and to add break; at the end of each line
          default:
             //do nothing, or something, whatever
    }
 </script>
