ASP无刷新AJAX上传代码示例

特别提示：本代码引用了化境ASP无组件代码

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：

Public Function CheckAndCreateFolder(FolderName)
set fso=server.createobject("scripting.filesystemobject")
if fso.fileexists(server.mappath(FolderName)) then
CheckAndCreateFolder="yes"
else
CheckAndCreateFolder="no"
end if
set fso=Nothing
End Function
filepath="upload/"
set upload=new upload_5xsoft'此处引用化境无组件上传
set file=upload.file("file")
if file.FileSize<>0 then
  fn=year(now)&month(now)&day(now)&hour(now)&minute(now)&second(now)&"."&file.FileExt
  file.saveas server.MapPath(filepath&fn)
If CheckAndCreateFolder(filepath&fn)="yes" then
 response.Write"usualtooltrue"&filepath&fn&""
 Else
 response.Write"usualtoolerror"
 End If 
else
  response.Write"usualtoolerror"
end If
