原文:构建ASP.NET MVC4+EF5+EasyUI+Unity2.x注入的后台管理系统（48）-工作流设计-起草新申请创建新表单之后，我们就可以起草申请了，申请按照严格的表单步骤和分支执行。
起草的同时，我们分解流转的规则中的审批人并保存，具体流程如下
接下来创建DrafContoller控制器，此控制器只有2个页面，一个Create（起草页面）Index（表单列表）
表单列表显示个人想法，我是根据分类直接获取其下表单，即Flow_Type下的Flow_Form
public ActionResult Index() { List<Flow_TypeModel> list = m_BLL.GetList(ref setNoPagerAscBySort, ""); foreach (var v in list) { v.formList = new List<Flow_FormModel>(); List<Flow_FormModel> formList = formBLL.GetListByTypeId(v.Id); v.formList = formList; } ViewBag.DrafList = list; return View(); }
@using App.Admin; @using App.Common; @using App.Models.Sys; @using App.Lang; @{ ViewBag.Title = "起草申请"; Layout = "~/Views/Shared/_Index_Layout.cshtml"; } <div style="padding:10px;"> @foreach (var v in (List<App.Models.Flow.Flow_TypeModel>)ViewBag.DrafList) { <fieldset class="accordion" style="margin: 0px; padding: 0px; padding-bottom:10px; margin-bottom: 10px;"> <legend class="tabs-header panel-title" style="border: 0px; padding: 5px; margin: 20px; margin-bottom:5px;">@v.Name</legend> <div style="padding-left:20px;color:#808080">备注：@v.Remark</div> <div style="padding: 0px 20px 40px 20px;"> @foreach (var r in v.formList) { <div style="float: left; width: 120px; margin:10px 0px 10px 0px;"> <a href="javascript:void(0)" class="easyui-linkbutton" data-options="plain:true,iconCls:‘icon-details‘" onclick="javascript:window.parent.addTab(‘@r.Name‘,‘/Flow/Draf/Create?id=@r.Id‘,‘icon-add‘)">@r.Name</a> </div> } </div> </fieldset> } </div>
上面的表单列表简单完成之后，进入最复杂的一步，获取字段组成表单
获取字段组成表单可以做得很漂亮，即在设计表单的时候设计布局，直接读取布局，否则按照表单的控件顺序读取布局。
具体对比如下：
VS
明显前者更利于打印和阅读。我们先布局第二种形式
根据表Flow_FormContent设置Create页面的固定头尾
@model App.Models.Flow.Flow_FormContentModel @using App.Common; @using App.Models.Flow; @using App.Admin; @using App.Models.Sys; @{ ViewBag.Title = "创建"; Layout = "~/Views/Shared/_Index_Layout.cshtml"; List<permModel> perm = (List<permModel>)ViewBag.Perm; if (perm == null) { perm = new List<permModel>(); } } <script src="~/Scripts/My97DatePicker/WdatePicker.js"></script> <script type="text/javascript"> $(function () { $("#btnSave").click(function () { if ($("#Title").val() == "") { $.messageBox5s("提示", "表单标题必须填写！"); return false; } if (CheckForm()) { $.ajax({ url: "@Url.Action("Create")", type: "Post", data: $("form").serialize(), dataType: "json", success: function (data) { if (data.type == 1) { $.messageBox5s("添加成功！", data.message); $("#btnSave").hide(); } else { window.parent.frameReturnByMes(data.message); } } }); } return false; }); $("#btnReturn").click(function () { if ($("#btnSave").is(":hidden")) { window.parent.CloseCurrentWin(); } else { $.messager.confirm(‘提示‘, ‘没有保存的数据将会丢失，你确定要返回吗？‘, function (r) { if (r) { window.parent.CloseCurrentWin(); } }); } }); }); </script> @Html.Raw(ViewBag.HtmlJS) <div class="mvctool "> @Html.ToolButton("btnSave", "icon-save", "保存", perm, "Create", true) @Html.ToolButton("btnReturn", "icon-return", "返回",false) </div> @using (Html.BeginForm()) { <table class="fromEditTable setTextWidth300"> <tbody> @Html.HiddenFor(model => model.Id) @Html.HiddenFor(model => model.FormId) @Html.HiddenFor(model => model.UserId) <input id="CreateTime" type="hidden" name="CreateTime" value="2000-1-1" /> <input id="TimeOut" type="hidden" name="TimeOut" value="2111-1-1" /> <tr> <td style="width:100px; text-align:right;"> @Html.LabelFor(model => model.Title)： </td> <td style="width:310px"> @Html.EditorFor(model => model.Title) </td> <td>@Html.ValidationMessageFor(model => model.Title)</td> </tr> @Html.Raw(ViewBag.Html) <tr><td style=‘width:100px; text-align:right;‘>紧急程度 :</td><td><select name="FormLevel" id="FormLevel"><option value="普通">普通</option><option value="重要">重要</option><option value="紧急">紧急</option></select></td></tr> </tbody> </table> }
代码
@Html.Raw(ViewBag.Html)就是我们的表单核心部分。所以Create必须返回ViewBag.Html内容为设计表单的JS和字段
这里代码有点别扭，因为有26个字段，所以要循环26个字段去判断是否有关联来读取。很麻烦。可以用反射来做可以省很多代码
先创建一个类，这个类是辅助工作流的通用类
using App.Models.Flow; using System; using System.Collections.Generic; using System.Linq; using System.Web; namespace App.Admin { public class FlowHelper { //获取指定类型的HTML表单 public string GetInput(string type, string id, string attrNo) { string str = ""; if (type == "文本") { str = "<input id=‘" + id + "‘ name=‘" + attrNo + "‘ type=‘text‘ />"; } else if (type == "多行文本") { str = "<textarea id=‘" + id + "‘ name=‘" + attrNo + "‘ cols=‘60‘ style=‘height: 80px;‘ rows=‘5‘></textarea>"; } else if (type == "日期") { str = "<input type=‘text‘ name=‘" + attrNo + "‘ class=‘Wdate‘ onfocus=\"WdatePicker({dateFmt:‘yyyy-MM-dd‘})\" id=‘" + id + "‘ />"; } else if (type == "时间") { str = "<input type=‘text‘ name=‘" + attrNo + "‘ class=‘Wdate‘ onfocus=\"WdatePicker({dateFmt:‘yyyy-MM-dd HH:mm‘})\" id=‘" + id + "‘ />"; } else if (type == "数字") { str = "<input type=‘number‘ name=‘" + attrNo + "‘ id=‘" + id + "‘ />"; } return str; } } }
[SupportFilter] public ActionResult Create(string id) { ViewBag.Perm = GetPermission(); ViewBag.Html = ExceHtmlJs(id); Flow_FormContentModel model = new Flow_FormContentModel(); model.FormId = id; return View(model); } //根据设定公文，生成表单及控制条件 private string ExceHtmlJs(string id) { //定义一个sb为生成HTML表单 StringBuilder sbHtml = new StringBuilder(); StringBuilder sbJS = new StringBuilder(); sbJS.Append("<script type=‘text/javascript‘>function CheckForm(){"); Flow_FormModel model = formBLL.GetById(id); #region 判断流程是否有字段,有就生成HTML表单 //获得对象的类型，model Type formType = model.GetType(); //查找名称为"A-Z"的属性 string[] arrStr = { "AttrA", "AttrB", "AttrC", "AttrD", "AttrE", "AttrF", "AttrG", "AttrH", "AttrI", "AttrJ", "AttrK" , "AttrL", "AttrM", "AttrN", "AttrO", "AttrP", "AttrQ", "AttrR", "AttrS", "AttrT", "AttrU" , "AttrV", "AttrW", "AttrX", "AttrY", "AttrZ"}; foreach (string str in arrStr) { object o = formType.GetProperty(str).GetValue(model, null); if (o != null) { sbHtml.Append(JuageExc(o.ToString(), str, ref sbJS)); } } #endregion sbJS.Append("return true}</script>"); ViewBag.HtmlJS = sbJS.ToString(); return sbHtml.ToString(); } private string JuageExc(string attr, string no,ref StringBuilder sbJS) { if (!string.IsNullOrEmpty(attr)) { return GetHtml(attr, no, ref sbJS); } return ""; } //获取指定名称的HTML表单 private string GetHtml(string id, string no, ref StringBuilder sbJS) { StringBuilder sb = new StringBuilder(); Flow_FormAttrModel attrModel = formAttrBLL.GetById(id); sb.AppendFormat("<tr><td style=‘width:100px; text-align:right;‘>{0} :</td>", attrModel.Title); //获取指定类型的HTML表单 sb.AppendFormat("<td>{0}</td></tr>", new FlowHelper().GetInput(attrModel.AttrType, attrModel.Name, no)); sbJS.Append(attrModel.CheckJS); return sb.ToString(); }
引入命名空间using System;
代码结构：上面没有什么特殊算法。主要是26个字段用反射来读取。自己细细消化一下就行
应该可以用了，点击请假申请看看！
完成。可以起草新的申请了。接下来就是保存申请...
保存是最复杂的一步要取得表单，分解步骤，分解分支，最后指定审核人
看Create方法

代码分析：
1.填充表单内容Flow_FormContent
2.获得表单步骤Flow_Step
3.根据步骤获得Flow_StepRule
4.取得判断流程方向的标示（是否结束）
5.插入审批人
需要慢慢消化，分解过程比较复杂
