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
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(); }
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>
Index.cshtml
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;
} }
}
FlowHelper.cs
[SupportFilter]

ViewBag.HtmlJS = sbJS.ToString();
return sbHtml.ToString();

{

return "";
}
//获取指定名称的HTML表单
private string GetHtml(string id, string no, ref StringBuilder sbJS)
{

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

获取人员代码
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
