ASP.NET MVC+BUI实现表格的操作
在Web中基于表格的操作，比如添加行、单元格内容编辑等等功能，是完全基于js实现的。但如果程序员完全使用js或者jquery去编写表格控件，则会导致样式不统一，代码量较大等问题，尤其对于不太熟悉js的后端程序员来说，可能会是一个挑战。因此，网络上出现了很多基于表格操作的js控件，帮助程序员尤其是后端程序员也能够编写出漂亮的基于表格的应用。本篇博客以ASP.NET MVC+BUI为例，看如何实现基于表格的分页查询、编辑、删除等功能。
首先介绍一下BUI。BUI是基于jQuery开发的轻量级的控件库，官网链接为：http://www.builive.com/demo/index.php。程序员只要参照示例中的js代码，提供后端数据源部分，就能实现数据操作。要使用bui首先要去官网下载bui控件包，将其文件放入到ASP.NET MVC项目中的Scripts目录下，然后在cshtml文件中引用css、js即可。
我们这篇博客要实现的功能大概如下。首先点击查询按钮，显示出当前的数据（支持分页）。
点击修改时出现的界面，会加载选中表格的行的数据。
点击删除，会出现对话框。点击确定按钮，会删除对应表格的行的信息，并自动刷新表格内容。

CXDYController中的DACXResult方法代码：
/// <summary> /// 档案查询结果 /// </summary> /// <returns></returns> [HttpGet] public JsonResult DACXResult() { using (dao as IDisposable) { int start = int.Parse(Request["start"] ?? "20"); int limit = int.Parse(Request["limit"] ?? "10"); int pageIndex = int.Parse(Request["pageIndex"] ?? "1") + 1; int all = 0; #region where条件 string strWhere = string.Empty; if (!string.IsNullOrEmpty(Request["dwdm"])) { strWhere += "and dwdm = '" + Request["dwdm"] + "'"; } if (!string.IsNullOrEmpty(Request["gzdw"])) { strWhere += "and gzdw = '" + Request["gzdw"] + "'"; } if (!string.IsNullOrEmpty(Request["grsbdm"])) { strWhere += "and grsbdm = '" + Request["grsbdm"] + "'"; strWhere += "and (yxbz = '0' or yxbz = '1' or yxbz = '2')"; } if (!string.IsNullOrEmpty(Request["xm"])) { strWhere += "and xm = '" + Request["xm"] + "'"; strWhere += "and (yxbz = '0' or yxbz = '1' or yxbz = '2')"; } if (!string.IsNullOrEmpty(Request["sfzhm"])) { strWhere += "and sfzhm = '" + Request["sfzhm"] + "'"; } if (!string.IsNullOrEmpty(Request["dah"])) { strWhere += "and dah = '" + Request["dah"] + "'"; strWhere += "and (yxbz = '0' or yxbz = '1' or yxbz = '2')"; } if (!string.IsNullOrEmpty(Request["gzny"])) { strWhere += "and gzny = '" + Request["gzny"] + "'"; } if (!string.IsNullOrEmpty(Request["txny"])) { strWhere += "and txny = '" + Request["txny"] + "'"; } if (string.IsNullOrEmpty(Request["grsbdm"])&& string.IsNullOrEmpty(Request["xm"])&& string.IsNullOrEmpty(Request["dah"])) { strWhere += "and yxbz = '0'"; } #endregion string orderBy = "order by yxbz,to_number(dah) asc,gxsj desc"; DataSet ds = dao.GetListByPage2(strWhere, orderBy, start, limit, pageIndex, out all); int count = ds.Tables[0].Rows.Count; RYXX[] ryxxs = new RYXX[count]; for (int i = 0; i < count; i++) { RYXX ryxx = dao.DataRowToModel(ds.Tables[0].Rows[i]); ryxxs[i] = ryxx; } return new JsonResult() { Data = new PageData<RYXX>() { rows = ryxxs, results = all, hasError = false, error = "" }, MaxJsonLength = int.MaxValue, ContentType = "application/json", JsonRequestBehavior = JsonRequestBehavior.AllowGet }; } }
PageData泛型类代码（分页对象）：
public class PageData<T> where T : class { public T[] rows { get; set; } public int results { get; set; } public bool hasError { get; set; } public string error { get; set; } }
RYXX实体类代码：
/// <summary> /// 人员信息 /// </summary> public class RYXX { /// <summary> /// 单位代码 /// </summary> public string DWDM { get; set; } /// <summary> /// 工作单位 /// </summary> public string GZDW { get; set; } /// <summary> /// 个人社保代码 /// </summary> public string GRSBDM { get; set; } /// <summary> /// 姓名 /// </summary> public string XM { get; set; } /// <summary> /// 身份证号码 /// </summary> public string SFZHM { get; set; } /// <summary> /// 工作年月 /// </summary> public string GZNY { get; set; } /// <summary> /// 退休年月 /// </summary> public string TXNY { get; set; } /// <summary> /// 档案号 /// </summary> public string DAH { get; set; } /// <summary> /// 退休类型 /// </summary> public string TXLX { get; set; } /// <summary> /// 有效标志（0表示正常，1表示死亡） /// </summary> public string YXBZ { get; set; } /// <summary> /// 档案扫描人 /// </summary> public string SMR { get; set; } /// <summary> /// 数据导入人 /// </summary> public string DRR { get; set; } }
GetListByPage2分页代码（基于Oracle的分页查询）：
/// <summary> /// 分页获取数据 /// </summary> /// <param name="strWhere">where条件</param> /// <param name="orderBy">排序</param> /// <param name="start">开始记录的起始数，如第 20 条,从0开始</param> /// <param name="limit">单页多少条记录</param> /// <param name="pageIndex">第几页，同start参数重复，可以选择其中一个使用</param> /// <param name="all">记录总数</param> /// <returns>分页数据</returns> public DataSet GetListByPage2(string strWhere, string orderBy, int start, int limit, int pageIndex, out int all) { string sql1 = "SELECT * FROM T_RYXX where 1=1 " + strWhere + " " + orderBy; all = OracleHelper.Query(sql1).Tables[0].Rows.Count; string sql = @"SELECT * FROM (SELECT A.*, ROWNUM RN FROM (SELECT * FROM T_RYXX where 1=1" + strWhere + " " + orderBy + ") A WHERE ROWNUM <= '" + limit * pageIndex + "') WHERE RN > '" + start + "'"; return OracleHelper.Query(sql); }
DAManage中的ModifyRY和DelRY方法代码就不贴了，与上述Action中的查询代码思路类似（Request获取参数，然后后端执行一下sql返回标志，前端success回调函数处理）。通过上面的例子可以看出，现在Web开发大部分都是js代码，C#代码只占很少部分。因此熟练掌握js对于web开发来说是第一位的。
