form必须加这个属性enctype="multipart/form-data",否则后台获取不到文件

 1 <script>
 2 function uploadFiles() {
 3     $('#fm').form('submit', {                
 4                 url: 'Upload.aspx?fjssmk=Xmgl',
 5                 success: function (result) {
 6                     var result = eval('(' + result + ')');
 7                     //可以写一些提示的代码等等..
 8                 }
 9             });
10 }
11 </script>
1 <form id="fm" method="post" enctype="multipart/form-data">
2     <input id="upload1" class="easyui-filebox" name="file1" data-options="prompt:'选择文件...',onChange:function(){uploadFiles()}" style="width: 150px" />
3 </form>

 asp.net 后台代码 , 其中Sys_fjxx为一个Model文件, 可以去掉 , 对数据库的操作改成你自己的就可以了, 

 1 public class Upload : IHttpHandler, IRequiresSessionState
 2     {
 3 
 4         public bool IsReusable
 5         {
 6             get { return false; }
 7         }
 8 
 9         public void ProcessRequest(HttpContext context)
10         {
11             try
12             {
13                 string fjssmk = context.Request["fjssmk"];
14                 string userid = Utility.GetCurrentUser().zybh + "";
15 
16                 HttpFileCollection httpFileCollection = context.Request.Files;
17                 HttpPostedFile file = null;
18                 if (httpFileCollection.Count > 0)
19                     file = httpFileCollection[0];
20                 if (file != null)
21                 {
22                     DBHelp.DBExecute exe = new DBHelp.DBExecute();
23                     Sys_fjxx fjxx = ConvertFile(file);

26                     fjxx.scrbh = int.Parse(userid);
27                     //
