jquery easyui filebox 上传附件 + asp.net后台

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,
