我对css和javascript都是完整的n00b很抱歉，如果这可能是基本的东西......我正在尝试整理一个显示建筑物概述的表格。 当用户点击任何楼层链接时，一个表格会变为另一个表格（它们都在不同的div中。当用户将鼠标移到它上面时，会显示有关每个单位的更多信息，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，可以在单击时更改每个单独单元格的背景。因此，例如，当点击show rental units时，所有单元格的背景都会被更改，其中id ='rent'和'both' 在此处查看演示：http://encanto.ximg.co/overviewdemo.html
下面是第一个表的完整源代码（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个混乱。但是我只能找到告诉td在你点击td而不是href时改变颜色的函数。 正如我所说，我是一个完整的n00b所以请温柔。

答案 0 :(得分：0)
您拥有获得预期结果所需的一切。您提供的两种JavaScript函数都有基本逻辑。您只需要告诉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制作两个新函数（例如：highlightCell），并更改for循环内更改的属性。
