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]        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

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
