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

系列目录

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(); }

Index ActionResult

@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：

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 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;   }  } }

FlowHelper.cs

[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
