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 }, { field: ‘Remark‘, title: ‘步骤说明‘, width: 280, sortable: true }, { field: ‘Sort‘, title: ‘排序‘, width: 80, sortable: true, hidden: true }, { field: ‘FormId‘, title: ‘所属表单‘, width: 80, sortable: true, hidden: true }, { field: ‘FlowRule‘, title: ‘流转规则‘, width: 80, sortable: true }, { field: ‘Action‘, title: ‘操作分支‘,align:‘center‘, width: 80, sortable: true } ]] }); }); //ifram 返回 function frameReturnByClose() { $("#modalwindow").window(‘close‘); } function frameReturnByReload(flag) { if (flag) $("#List").datagrid(‘load‘); else $("#List").datagrid(‘reload‘); } function frameReturnByMes(mes) { $.messageBox5s(‘提示‘, mes); } function SetRule(stepId) { $("#modalwindow").html("<iframe width=‘100%‘ height=‘100%‘ scrolling=‘no‘ frameborder=‘0‘‘ src=‘/Flow/Form/StepRuleList?stepId=" + stepId + "&formId=@(ViewBag.FormId)‘></iframe>"); $("#modalwindow").window({ title: ‘设置分支‘, width: 620, height: 300, iconCls: ‘icon-add‘ }).window(‘open‘); } </script>
[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 stepList select 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 = "<a href=‘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。
