前端JS部分：

function upload(id){
                $("#imgWait"+id+"").show();
                var formData = new FormData();
                formData.append("file", document.getElementById("file"+id+"").files[0]);
                //通过formData提交数据
                $.ajax({
                    url: "upload.asp",
                    type: "POST",
                    data: formData,
                    contentType: false,
                    processData: false,
                    success: function (data) {
						if(data.indexOf("usualtooltrue") >= 0 ) {
							var datas = data.split('usualtooltrue');
							$("#list"+id+"").val(datas[1]);
                            alert("上传成功！");
                        }else{
                        alert("上传失败！");
                        }
                        $("#imgWait"+id+"").hide();
                    },
                    error: function () {
                        alert("上传失败！");
                        $("#imgWait"+id+"").hide();
                    }
                });
            }

后端部分：
