做web设计的时候,经常会遇到父表,子表的问题,例如:班级表&学生表, 集群表&主机表等等。。说白了就是数据库设计中的一对多关系的情况。

这种状况在做页面展示的时候,做成伸缩表格的样子比较灵活点。下面是我参照了一个开源的jquery插件实现的动态伸缩表格,大家可以参照一下。

首先,上效果图:

比较简陋,只用了最简单的css效果,下面贴出我的代码。

1. 文件名:test.css

table.expanding {
        margin-top:2px;
        margin-left:20px;
        #background-color: #FFF;
        #background:#EEF4F9;
        #border: none;
        border: 1;
        #color:#003755;
        border-collapse:collapse;
        font: 14px  "宋体";
}

table.expanding th{
        background:#7CB8E2;
        color:#fff;
        padding:8px 10px;
        text-align:center;
}

table.expanding tr.odd td{
        background:#C7DDEE none repeat-x scroll center left;
        color:#000;
        padding:4px 2px;
}

table.expanding a{
        text-decoration:none;
        height:1em;
}

table.expanding a:link, table.expanding  a:visited{
        color:#3366CC;
}
table.expanding  a:hover{                                      /* 鼠标经过时 */
        color:#B50000;
        text-decoration:underline;
}
