使用 new FormData 上传文件导致IE不兼容的问题

好吧，直奔主题！
多数浏览器都支持new FormData($( "#fileUploadForm")[0]),但是IE10下却显示
FormData未定义

  //AJAX文件上传
        $.ajax({
            url: path + "/fileManager/uploadFile",
  type: 'post',
            data:  new FormData($( "#fileUploadForm")[0]),
            async: true, 
            cache: false, 
            contentType: false,  // 告诉jQuery不要去处理发送的数据
            processData: false,  // 告诉jQuery不要去设置Content-Type请求头
            success: function (data) {
            mini.hideMessageBox(messageid);
            mini.confirm(data.msg ,"提示",function delConfirm(action){
            window.CloseOwnerWindow();
            });
             },
            error: function (data) {
            mini.hideMessageBox(messageid);
            var msg = data.msg;
            if(null == msg || "" == msg || "undefined" == msg){
            msg = "操作出现异常";
            }
          mini.confirm(msg ,"提示",function delConfirm(action){
            window.CloseOwnerWindow();
            });
            }
        });
}

怎么办呢？只有换一个提交策略了ajaxSubmit
$("#batchAdd").ajaxSubmit({
          type: 'post', 
          url: path+'/sysInfo/importSysInfo', 
          success: function (data) {
          var msssage = JSON.parse(data);
              mini.alert(msssage.msg ,"提示",function ImportSysConfirm(action){
         window.CloseOwnerWindow();
         });
          },
          error: function (data) {
        var msssage = JSON.parse(data);
        var msg = msssage.msg;
          if(null == msg || "" == msg || "undefined" == msg){
          msg = "操作出现异常";
          }
        mini.alert(msg,"提示",function ImportSysConfirm(action){
          window.CloseOwnerWindow();
          });
          }
      }); 

  不过这里的时候也出现了一个问题，由于返回的时候JSON，IE8总是要提示是否下载JSON文件
好办取配置文件里配一下
       
           
               
                   
                                             
                        text/html;charset=UTF-8   
                       
                   
                   
                     
                           
                           
                               
                                   
                               
                          
                         
                         
                            NON_NULL 
                          
                       
                   
               
           


大功告成
