積分系統總結

今天積分系統MPM (Merit  Points Management) 完成。javascript

asp.net MVC4.0 EF DBFirst   EasyUI 登錄頁面採用bootstrap。(仍是bootstrap好看些!)html

功能不多,就一個模型層,和一個 webUI 展示層。java

權限判斷採用 過濾器,每個Action都會通過過濾器。web

public class FilterConfig { public static void RegisterGlobalFilters(GlobalFilterCollection filters) { filters.Add(new HandleErrorAttribute()); filters.Add(new MyActionFilterAttribute()); } /// <summary> /// 標記爲NoFilterAttribute 屬性的的方法,過濾器在這裏撲捉到,而後 直接 return,不作權限管控 /// </summary>  [AttributeUsage(AttributeTargets.Method)] public class NoFilterAttribute : Attribute { } /// <summary> /// Action方法 過濾器 類 /// </summary> public class MyActionFilterAttribute : ActionFilterAttribute { /// <summary> /// 在 Action方法以前 調用 /// </summary> /// <param name="filterContext"></param> public override void OnActionExecuting(ActionExecutingContext filterContext) { string strController = filterContext.RouteData.Values["controller"].ToString(); if (strController == "Login" || strController == "Home") { return; } object[] attrs = filterContext.ActionDescriptor.GetCustomAttributes(typeof(NoFilterAttribute), true); if (attrs.Length > 0) return; HttpSessionStateBase session = filterContext.HttpContext.Session; if (session != null) { var activeSession = session["KT.MPM.web"]; if (activeSession == null) { filterContext.HttpContext.Response.Redirect("/Login"); return; } var userWorkNum = activeSession.ToString(); var mpmDb = new MPMEntities(); if (mpmDb.SysPower.FirstOrDefault(x => x.UserWorkNum == userWorkNum) == null) { filterContext.HttpContext.Response.Redirect("/Login"); } } base.OnActionExecuting(filterContext); } } }
View Code

這樣作呢,仍是比較消性能的。ajax

UI  框架的搭建  沒有  採用 Easyui 官方 documentation 頁面的那種,不採用Iframe,直接 ajax 加載 子頁面。這樣速度確實很快。缺點就是很差調試。json

 我使用了Iframebootstrap

主頁面代碼以下:session

@{
    ViewBag.Title = "Index";
    Layout = "~/Views/Shared/_Layout.cshtml";
}
<style>
    .treegrid-tr-tree td {
        border-style: none;
    }

    .datagrid-btable td {
        border-style: none;
    }
</style>
<body class="easyui-layout" style="text-align: left">
    <div region="west" split="true" title="菜單" style="width: 250px; padding: 5px;">
        <table   id="MenuTree" style="width:100%" title="" class="easyui-treegrid" data-options="
    method:'post',
    url:'@Url.Action("Index")',onClickRow:fun,
    treeField:'MenuName',
    fixed:true,  
    idField:'MenuID' 
    ">
            <thead>
                <tr>
                    <th data-options="field:'MenuName',width:230,formatter:formatUrl"></th>
                </tr>
            </thead>
        </table>

        <script>
            function fun(row) {
                addTab(row.MenuName, row.Url);
            }
            function formatUrl(val, row) {
                if (row.Url != "") {
                    return '<span class="e-link" href="javascript:void(0)" onclick="addTab(' + "'" + row.MenuName + "'" + ',' + "'" + row.Url + "'" + ')">' + row.MenuName + '</span>';
                } else {
                    return '<a class="e-link" href="javascript:void(0)">' + row.MenuName + '</a>';
                }
            }
            $(document).ready(function () {

            });
        </script>
    </div>
    <div region="center">
        <div id="tt" class="easyui-tabs" fit="true" border="false" plain="true">
        </div>
    </div>
    <script>
        function addTab(title, url) {
            if ($('#tt').tabs('exists', title)) {
                $('#tt').tabs('select', title);
            } else {
                var content = '<iframe scrolling="auto" frameborder="0"  src="' + url + '" style="width:100%;height:99%;"></iframe>';
                $('#tt').tabs('add', {
                    title: title,
                    content: content,
                    closable: true
                });
            }
        }
        function showMsgTopCenter(title, msg) {
            $.messager.show({
                title: title,
                msg: msg,
                showType: 'null', showSpeed: 0,
                style: {
                    top: document.body.scrollTop + document.documentElement.scrollTop,
                    timeout: 1000
                }
            });
        }

    </script>
View Code

easyui  請求的數據都是  JSON 格式,因此項目中 大量用到了 json.net
好比一個有頁腳的json  :app

  public string UserOtherRecordForOther(UserOtherRecordData model) { var dataGridJson = new DataGridJson(); var data = _mpmDb.view_UserOtherRecordForOther.Where(x => x.ObjectUser == model.RecordUser).Where( y => y.CreateDate == model.CreateDate).ToList(); dataGridJson.rows = data; dataGridJson.footer = new List<view_UserOtherRecordForOther>() { new view_UserOtherRecordForOther() { AllPoint=data.Sum(x=>x.AllPoint), OutputValue=data.Sum(x=>x.OutputValue) } }; return JsonConvert.SerializeObject(dataGridJson); } public class DataGridJson { public static int i = 10; public int total { get; set; } //記錄的總條數 public object rows { get; set; } //具體內容 public object footer { get; set; } //具體內容 }
View Code

 裏面必須再包一層List.框架

使用到了一個擴展方法 來獲取 當前登錄用戶的工號。

namespace KT.MPM.web.Controllers
{
    public static class Expend
    {
        public static string GetUserWorkNum(this Controller controller)
        {
            return controller.Session["KT.MPM.web"].ToString();
        }
    }
}
View Code

也有人說,直接 寫一個類,繼承 Controller 類不就行了嘛。

還有一個Excel 導出功能。

使用的是 NPOI 。

function ToExcel() {
    location.href = '@Url.Action("ExportExcel", "EveryDayPointReport")' + '?createDate=' + CreateDate_Temp;
}
View Code
  [FilterConfig.NoFilterAttribute]
        public ActionResult ExportExcel(DateTime? createDate)
        {
            String newfileName = DateTime.Now.ToString("yyyyMMddHHmmssff");
            var list = Search(createDate);
            var fileOne = new FileStream(Server.MapPath("/template/EveryDayReport.xls"), FileMode.Open, FileAccess.ReadWrite);
            var wbOne = new HSSFWorkbook(fileOne);
            var sheet = (HSSFSheet)wbOne.GetSheetAt(0);
            int startRow = 2;
            foreach (var item in list)
            {
                var rowOne = (HSSFRow)sheet.CreateRow(startRow);
                rowOne.CreateCell(0).SetCellValue(item.UserWorkNum);
                rowOne.CreateCell(1).SetCellValue(item.UserName);
               。。。。。。
                startRow = startRow + 1;
            }
            var ms = new MemoryStream();
            wbOne.Write(ms);
            return File(ms.ToArray(), "application/vnd.ms-excel",
                        HttpUtility.UrlEncode(string.Format("{0}.xls", newfileName)));
        }
View Code

MVC就這點好,這樣寫,永遠不會啓動迅雷以後下載到錯誤的頁面。之前用aspx 頁面裏面的導出功能,直接就把aspx頁面給下載過來了。必須用通常處理程序作。

每次 dataGrid 查詢,只不過是 輕量級 的發送 輕量級 的送回來(只須要更改datagrid 的url 參數)。服務端 客戶端 都消耗  比較少。
