//限制文件上传大小

var isIE = /msie/i.test(navigator.userAgent) && !window.opera;

function checkuploadPicIcon(target,name){

             var fileSystem = new ActiveXObject("Scripting.FileSystemObject" );         

             var file = fileSystem.GetFile (filePath);      

            fileSize = file.Size;    

      } else {     

            fileSize = target.files[0].size;      

      }    

       var size = fileSize / 1024;   

    if(size>15){

      $( "#"+name).val( "" );

            alert( "图片不能超过15K,请重新上传！" );

      }   

}

在JSP页面中调用上传文件：

<td>

  <s:file id ="doctorVideoIco" name ="upload1"onchange="checkuploadPicIcon(this,'doctorVideoIco')" ></s:file>

</td>
