javascript - onclick href 更改 td 背景

Question

我对 css 和 javascript 完全不熟悉，如果这可能是一些基本的东西，我很抱歉。我正在尝试整理一个显示建筑物概览的表格。当用户单击任何楼层链接时，一个表格会更改为另一个表格(它们都在不同的 div 中。当用户将鼠标移到它上面时，它会显示有关每个单独单元的更多信息，无论是出租、出售，还是无法使用。我现在要创建的是一些链接，这些链接在单击时会更改每个单元格的背景。因此，例如，当点击 show rental units 时，id='rent' 和 'both' 的所有单元格的背景都会发生变化在此处查看演示:http://encanto.ximg.co/overviewdemo.html

这是第一个表格的完整源代码(包括 css)。我确定它在我试图显示/隐藏 td 单元格的某个地方也是一团糟。但我似乎只能找到告诉 td 在您单击 td 时更改颜色的函数，而不是 href。正如我所说，我是一个彻头彻尾的 n00b，所以请保持温柔。

    <style type="text/css">
table.overview a {  
border:none;    
display: block; 
}

table.overview td {
    max-height:150px;
    max-width:150px;
    background:#96843c;
}

div.overview td:hover {
    background:#ffffff;
}

div.overview td.white {
    background:#ffffff;
}

div.overview    a {
color: #ffffff; 
text-decoration:none;
text-align:center;
letter-spacing: 1px; 
font-size:16px; 
line-height:32px; 
font-family:"Century Gothic", helvetica, sans-serif;
padding: 2px 5px;
}

div.overview    p   {
color:#96843c;
text-decoration:none;
text-align:center;
letter-spacing: 1px;
font-size:10px;
line-height:10px;
font-family:Georgia, "Times New Roman", Times, serif;
}

div.overview    a:hover {
color: #96843c;
background: #ffffff;
font-family: "Century Gothic";
}



</style>

Answer 1

您已拥有获得预期结果所需的一切。基本逻辑存在于您提供的两个 JavaScript 函数中。您只需告诉 JavaScript 更改 backgroundColor 而不是更改 display 属性。

我建议使用更具描述性的名称创建两个新函数(例如:highlightCell)并更改在 for 循环中更改的属性。
