原文:构建ASP.NET MVC4+EF5+EasyUI+Unity2.x注入的后台管理系统（46）-工作流设计-设计分支
步骤设置完毕之后，就要设置好流转了，比如财务申请大于50000元（请假天数>5天）要总经理审批，否则财务审批之后就结束了。
设置分支没有任何关注点，我们把关注点都放在了用户的起草表单。所以本节如同设置字段，设置步骤一样，只需要填充好Flow_StepRule表
表结构：Flow_StepRule表主要是字段对比值，所以需要操作符，我们约定操作符为=、>、<、<=、>=、!=六种
表Flow_StepRule的主表是Flow_Step，所以跟步骤一样为主从关系的设置
我是这样设计的，先获取步骤列表，再按列表的步骤来设置分支，如图
分支具体代码如下
<table id="List"></table>
<div id="modalwindow" class="easyui-window" data-options="modal:true,closed:true,minimizable:false,shadow:false"></div>
<script type="text/javascript">
$(function () {
$('#List').datagrid({
url: '@Url.Action("GetStepList")?id=@(ViewBag.FormId)',
width: SetGridWidthSub(10),
methord: 'post',
height: SetGridHeightSub(39),
fitColumns: true,
sortName: 'Sort',
sortOrder: 'asc',
idField: 'Id',
pageSize: 15,
pageList: [15, 20, 30, 40, 50],
pagination: true,
striped: true, //奇偶行是否区分
singleSelect: true,//单选模式
//rownumbers: true,//行号
columns: [[
{ field: 'StepNo', title: '步骤', width: 80 },
{ field: 'Id', title: '', width: 80, hidden: true },
{ field: 'Name', title: '步骤名称', width: 80, sortable: true },

]]
});
});

点击操作分支按钮将弹出分支的添加和删除

写了这么多都是为了填充这种主从表关系的数据，目前为止都很容易消化。
