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。

最佳答案
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。
关于javascript - onclick href 更改 td 背景，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/7315571/
