道理相通，我简单分享下在.net MVC下的实装。
1.制作Model类
using System; using System.Collections.Generic; using System.Linq; using System.Web; namespace RCRS.WebApp.LG.EM.Models { //---------------------------------------------------------------- /// <summary> /// Import画面用 /// </summary> //---------------------------------------------------------------- public class tmp_UploadFile { /// <summary></summary> public HttpPostedFileBase FileName { get; set; } } }
2.实装controller里的对应方法，我这个处理逻辑比较复杂，懒得修改了，反正就这个意思
//---------------------------------------------------------------- /// <summary> /// アップロード /// </summary> /// <returns></returns> //---------------------------------------------------------------- [HttpPost] public virtual ActionResult UploadFile() { HttpPostedFileBase uploadedFile = Request.Files["FileName"]; string message = "アップロード失敗しました。"; bool isUploaded = false; string path = ""; string dateTimeNow = DateTime.Now.ToString("yyMMdd-hhmmss"); string userName = User.Identity.GetUserName(); string uploadMsg = string.Empty; if (uploadedFile != null && uploadedFile.ContentLength != 0) { string pathForSaving = Server.MapPath("~/App_Data/Uploaded/"); try { if (BsnssBihin.IsExcel(uploadedFile.FileName)) { path = System.IO.Path.Combine(pathForSaving, dateTimeNow + "_" + uploadedFile.FileName); uploadedFile.SaveAs(path); isUploaded = BsnssBihin.UploadBihinChange(path, userName, ref uploadMsg); if (isUploaded) { message = "アップロード成功しました！" + "n" + uploadMsg; Logger.Info("[成功]備品アップロード, " + dateTimeNow + ", " + "[" + userName + "]" + "[" + path + "]" + uploadMsg); } else { message = "アップロード失敗しました。" + "n" + uploadMsg; Logger.Info("[失敗]備品アップロード, " + dateTimeNow + ", " + "[" + userName + "]" + "["+path + "]" + uploadMsg); } } else { message = "ファイルの形式は不正です。"; } } catch (Exception ex) { message = string.Format("失敗しました: {0}", ex.Message); Logger.Info("[失敗]備品アップロード: " + ex.Message + dateTimeNow + ", " + "[" + userName + "]" + "[" + path + "]"); } } return Json(new { isUploaded = isUploaded, message = message }, "text/html"); }
3.页面的实装
@model RCRS.WebApp.LG.EM.Models.tmp_UploadFile <table align="center"> <tr> <td> <div> <input type="text" id="tbx-file-path" value="ファイルを選択してください" readonly="readonly" /> </div> </td> <td> <div> <span> <span>選 択</span> @Html.TextBoxFor(m => m.FileName, new { id = "file-upload", type = "file", accept = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, application/vnd.ms-excel" }) </span> </div> </td> <td> <div> <a href="#" id="hl-start-upload">アップロード</a> </div> </td> </tr> </table> <div id="loadingOver"></div> <div id="dvloader"> <span> 処理中、少々お待ちください</span><br /> <br /> <img id="loadingGif" src="../Content/img/loader.gif" alt="" /> </div> @section scripts{ @Scripts.Render("~/bundles/jquery") @Scripts.Render("~/bundles/jqueryui") @Scripts.Render("~/bundles/jqueryval") @Scripts.Render("~/bundles/common") @Scripts.Render("~/bundles/fileupload") <script type="text/javascript"> var data_upload; $(document).ready(function () { 'use strict'; $('#file-upload').fileupload({ url: '../Bihin/UploadFile', dataType: 'json', add: function (e, data) { data_upload = data; }, done: function (event, data) { if (data.result.isUploaded) { $("#tbx-file-path").val("ファイルを選択してください"); data_upload = ""; } $("#dvloader").css("display", "none"); $("#loadingOver").css("display", "none"); alert(data.result.message); }, fail: function (event, data) { data_upload = ""; if (data.files[0].error) { $("#dvloader").css("display", "none"); $("#loadingOver").css("display", "none"); alert(data.files[0].error); } } }); }); $("#hl-start-upload").on('click', function () { if (data_upload) { $("#dvloader").css("display", "block"); $("#loadingOver").css("display", "block"); data_upload.submit(); } return false; }); $("#file-upload").on('change', function () { $("#tbx-file-path").val(this.files[0].name); }); </script> }
√，就是这个样子
还附赠了一个简易loding的实现
贴出CSS代码：
.dvloader { display:none; position:absolute; top:40%; left:40%; width:20%; height:20%; z-index:1001; text-align:center; font-size:1.5em; } .loadingOver { display:none; position:absolute; top:0; left:0; width:100%; height:100%; background-color:#f5f5f5; opacity:0.5; z-index:1000; }
这里，多说一嘴：
关于input 的accept属性，这里只想读入Excel，所以
application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, application/vnd.ms-excel
