在我们自定义模型的时候 由于站的需要 需要的字段类型 官方目前不能满足
那么能否修改或增加新的字段类型呢？例如把下面的效果 做成一个字段类型
- <html>
- <head>
- <title>jQuery表格操作添加行、删除行和动态移动丨芯晴网页特效丨CsrCode.Cn</title>
- <script language="javascript" src="http://yuanhs1982.blog.163.com/blog/jquery.js"></script>
- </head>
- <body>
- <a href="http://yuanhs1982.blog.163.com/blog/#" onclick="add_line();">添加一行</a> <a href="http://yuanhs1982.blog.163.com/blog/#" onclick="remove_line
- ();">删除一行</a> <a href="http://yuanhs1982.blog.163.com/blog/#" onclick="up_exchange_line();">上移
- </a> <a href="http://yuanhs1982.blog.163.com/blog/#" onclick="down_exchange_line();">下移</a>
