本demo基于bootstrap-prettyfile.js

html代码如下：

1  <div id="file-pretty">
2                     <form id="ui-form-file-upload" name="form-file-upload" method="post" target="ui-iframe-file-upload" action="/Env/SoilSampleCheck/FileSubmit" enctype="multipart/form-data">
3                         <input type="file" name="fileName" class="form-control" style="display:none;">
4                         <input type="hidden" name="projectId" id="hidProjectId" />
5                     </form>
6                     <iframe name="ui-iframe-file-upload" id="ui-iframe-file-upload" style="position:absolute; top:-9999px; left:-9999px;"></iframe>
7                 </div>

JavaScript代码如下：

 1 //文件上传
 2                 $('#file-pretty input[type="file"]').prettyFile().change(function () {
 3 
 4                     var projectId = $("#hidProjectId").val();
 5                     if (projectId == "") {
 6                         tincher.message("请先选择项目", "error");
 7                     } else {
 8 
 9                         var param = { projectId: projectId };
10                         param = $.forgeryToken(param);
11                         tincher.execute("/Env/SoilSampleCheck/CheckSoilItem1", param, function (result, response) {
12                             if (result) {
13                                 $("#ui-form-file-upload").submit();
14                             } else {
15                                 tincher.message(response.message, "error");
16                             }
17                         });
18                     }
19                 });
20 
21   $("#ui-iframe-file-upload").on('load', function () {
22                     var response = "";
23                     if (this.contentWindow) {
24                         response = this.contentWindow.document.body ? this.contentWindow.document.body.innerText : null;
25 
26                     } else if (this.contentDocument) {
27                         response = this.contentDocument.document.body ? this.contentDocument.document.body.innerText : null;
28                     }
29                     if (response != "") {
30                         //有返回值
31                         var result = JSON.parse(response) || {};
32                         tincher.message(result.message);
33                         if (result.state == "success") {
34                             $("#hidFilePath").val(result.context.url);
35                             excelShow();
36                         }
37                     }
38                 })

C#代码如下：
