onclick href更改td背景

Question

我对css和javascript都是完整的n00b，因此，如果这可能是基本内容，则对不起。我试图将一张显示建筑物概况的表格放在一起。 当用户单击任何楼层链接时，一个表将更改为另一个表（它们都位于不同的div中。当用户将鼠标移到该表上时，它将显示有关每个单个单元的更多信息，无论该单元是可出租，可出售，可用于这两种类型，还是可用于我现在试图创建的是一些链接，这些链接在单击时会更改每个单个单元格的背景。例如，在单击“显示租赁单元”时，所有ID为“ rent”的单元格的背景都会更改和“两者”均可在此处查看演示： http : //encanto.ximg.co/overviewdemo.html

这是第一个表的完整源代码（包括CSS）。 我肯定它在我的某个地方也试图显示/隐藏td单元格。.但是我似乎只能找到单击td而不是href时告诉td更改颜色的函数。 如我所说，我是一个完整的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>

<script type="text/javascript"><!--

function show_visibility(){
for(var i = 0,e = arguments.length;i < e;i++){
var myDiv = document.getElementById(arguments[i]).style;
myDiv.display = "block";

}

Answer 1

您已经具备了获得预期结果所需的一切。 您提供的两个JavaScript函数都包含基本逻辑。 您只需要告诉JavaScript更改backgroundColor而不是更改display属性即可。

我建议创建两个具有更多描述性名称的新函数（例如： highlightCell ），并更改在for循环内更改的属性。
