Question

我想使用files and other data将ajax发送到servlet 所以我试着用下面的代码

 $("#upbtn1").click(function(event){ 
            event.preventDefault(); 
            var data1 = new FormData($("#formId1")[0]);

            $.ajax( {
              url: 'Proofs',
              type: 'POST',
              data :data1+"&t1="+$("id").val(),
              processData: false,
              contentType: false,
              dataType:"text",
              success:function(response)
              {  
              }

            }); 
          });

但它提供以下异常

如果我这样做只发送文件它不会给出任何异常，但当我发送两个files and other data令人不安时，如何发送这两个数据请帮助我。
