代码片段
实现目标：可以新建文件夹。默认文件夹排在列表前面并按照时间进行排序。为了减少查询的次数，需要添加一个字段标示是否是文件夹，可置为0，文件置为1，按照这个字段排序，并按照时间进行排序。
为MyFile类添加属性，IsFolder
public int IsFolder { get; set; }
修改文件上传，文件类型为1，并修改文件列表，按照文件类型，时间排序。
[HttpGet] public ActionResult FileList() { UserInfo userInfo = Session["user"] as UserInfo; if (userInfo == null) { return RedirectToAction("Login", "UserInfo"); } var fileList = _myFileServiceRepository.FindAll(x => x.User.Id == userInfo.Id && !x.IsDelete).OrderBy(x => x.IsFolder).OrderByDescending(x => x.CreateDt); ViewBag.UserInfo = userInfo; ViewBag.ChildTitle = "我的网盘"; return View(fileList); }
新建文件夹
public JsonResult CreateFolder() { UserInfo userInfo = Session["user"] as UserInfo; if (userInfo == null) { RedirectToAction("Login", "UserInfo"); } string folderPath = Request.Params["folderPath"]; string folderName = Request.Params["folderName"]; if (string.IsNullOrEmpty(folderName)) { throw new ArgumentNullException("文件夹名称不能为空"); } //检查文件夹是否已经存在 var count = _myFileServiceRepository.FindAll(x => x.User.Id == userInfo.Id && x.IsFolder == 0 && x.IsDelete == false && x.FileName.Contains(folderName)).Count(); userInfo = _userInfoServiceRepository.Find(x => x.Id == userInfo.Id); if (count > 0) { //如果不存在，则新建，否则进行自动重命名 folderName = folderName + "(" + (count + 1).ToString() + ")"; } if (string.IsNullOrEmpty(folderPath)) { folderPath = "/NetDisk/" + userInfo.UserName; } MyFile folder = new MyFile() { FilePath = folderPath + '/' + folderName, FileName = folderName, CreateDt = DateTime.Now, User = userInfo, FileExt = string.Empty, FileIcon = "/Content/Images/FolderType.png", FileMd5 = string.Empty, FileSize = 0, IsDelete = false, ModifyDt = DateTime.Now }; try { _myFileServiceRepository.Add(folder); _myFileServiceRepository.SaveChanges(); } catch (Exception) { return new JsonResult() { Data = new JavaScriptSerializer().Serialize(new { code = 500, msg = "创建失败" }) }; } return new JsonResult() { Data = new JavaScriptSerializer().Serialize(new { code = 200, folder = folder }) }; }
前端
<tbody role="alert" aria-live="polite" aria-relevant="all"> @{int i = 0;} @foreach (var item in Model) { i++; <tr class="i%2==0?'even':'odd'" id="tr-@item.Id"> @{ if (@item.FileMd5 != "") { <td class=" even sorting_1"><img src="@item.FileIcon" alt="" /> <span id="sp-@item.Id">@item.FileName</span></td> <td class="center ">@item.FileSize 字节</td> } else { <td class=" even sorting_1"> <a href="#" id="lnkFolder-@item.Id" onclick="clickFolder('sp-@item.Id')"> <img src="@item.FileIcon" alt="@item.FileName" /> <span id="sp-@item.Id">@item.FileName</span> </a> </td> <td class="center "></td> } } <td class="center ">@item.ModifyDt</td> <td class="center "> <a class="btn btn-info" href="javascript:void(0)" onclick="editFile(@item.Id,'@item.FileName')"> <i class="glyphicon glyphicon-edit icon-white"></i> 编辑 </a> <a class="btn btn-danger" href="javascript:void(0)" onclick="deleteFile(@item.Id)"> <i class="glyphicon glyphicon-trash icon-white"></i> 删除 </a> @{ if (@item.FileMd5 != "") { <a class="btn btn-success" href="/Home/DownLoadFile?fileId=@item.Id"> <i class="glyphicon glyphicon-zoom-in icon-white"></i> 下载 </a> } } </td> </tr> } </tbody>
jquery
//创建文件夹 $('#btnNewFolder').click(function () { //设置弹出框标题 var title = $('#alertTitlte').html(); $('#alertTitlte').html('新建文件夹'); //清空弹出框内容 $(".modal-body").html(''); $(".modal-body").html('<input type="text" placeholder="请输入名称" class="form-control" name="name" value="新建文件夹" id="txtFileName" />'); $('#txtFileName').val(''); $('#modal-edit').modal('show'); $('#txtFileName').val('新建文件夹'); $('#lnkSave').unbind('click'); $('#lnkSave').bind('click', function () { $.post('CreateFolder', { folderName: $('#txtFileName').val(), folderPath: $('#hdFilePath').val() }, function (data) { data = JSON.parse(data); var folder = data.folder; if (data.code == 200) { $('<tr class="odd"> <td class=" even sorting_1" id="fileName"> <a href="#" id="lnkFolder-' + folder.Id + '" onclick="clickFolder(sp-' + folder.Id + ')"><img src="/Content/Images/FolderType.png" id="fileicon" alt="" />' + folder.FileName + '</a></td><td class="center"></td><td class="center ">' + CurentTime() + '</td><td class="center "><a class="btn btn-info" href="#" id="fileEdit"> <i class="glyphicon glyphicon-edit icon-white"></i> 编辑 </a><a class="btn btn-danger" href="#"><i class="glyphicon glyphicon-trash icon-white" id="fileDelete"></i> 删除 </a> </td></tr>').insertBefore($('#fileList tbody')); }; //还原弹出框标题 $('#alertTitlte').html(title); }); }); });
