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; }
2. test_table.html
