form必須加這個屬性enctype="multipart/form-data",否則后台獲取不到文件
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 //可以寫一些提示的代碼等等.. 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:'選擇文件...',onChange:function(){uploadFiles()}" style="width: 150px" /> 3 </form>
asp.net 后台代碼 , 其中Sys_fjxx為一個Model文件, 可以去掉 , 對數據庫的操作改成你自己的就可以了,
