Question

所以我创建了一个表，并且我尝试为它添加onmouseover效果，因此我可以更改单元格的背景颜色。显然，当背景没有设定颜色时（在风格中），一切都像魅力一样。但是当它出现时，我无法想象它们......任何帮助？这是我的代码：

    .tableX td
    {

        padding: 5px;

        color: #FFFFFF;

    }
        .tableX td.largeLightBlue
        {
            height: 150px;
            -moz-border-radius: 7px;

onmouseover您只定位了您在CSS中使用的background-color，而不是background属性。设置style.background而不是style.backgroundColor可以解决问题。 JSFiddle Example
