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

<tableid="List"></table>
<divid="modalwindow"class="easyui-window"data-options="modal:true,closed:true,minimizable:false,shadow:false"></div>
<scripttype="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

[SupportFilter(ActionName = "Edit")]public ActionResult StepList(string id){ViewBag.FormId = id;return View();}[HttpPost][SupportFilter(ActionName = "Edit")]public JsonResult GetStepList(GridPager pager, string id){List<Flow_StepModel>stepList = stepBLL.GetList(ref pager, id);int i = 1;var json = new{total = pager.totalRows,rows = (from r in stepListselect new Flow_StepModel(){StepNo = "第 "+(i++)+" 步",Id = r.Id,Name = r.Name,Remark = r.Remark,Sort = r.Sort,FormId = r.FormId,FlowRule = r.FlowRule,Action = "<ahref='javascript:SetRule(\""+ r.Id + "\")'>分支(" + GetStepRuleListByStepId(r.Id).Count() + ")</a></a>"}).ToArray()};return Json(json);}

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。
