kendoUpload永远不会成功

Question

我让控件在页面加载时初始化，然后在按钮上单击它们，我想使用setOptions上传saveURL。问题是它永远不会打到onSuccess函数。

  

setOptions类是否缺少某些选项？

 $("#UploadDocumentFile").click(function (event) {

                var UploadDocumentFile = $("#UploadDocumentFile").data("kendoUpload");
                UploadDocumentFile.setOptions({
                    async: {
                        saveUrl: "/Shared/Upload.ashx?Meetingid=" + MeetingId + "&Action=" + selectedDocType,
                    },
                        success: onSuccess,
                        multiple: false,
                    });
                function onSuccess(e) {
                    if (e.operation == "upload") {
                        debugger;
                        console.log("%cSetting hfFileManagerId %s", 'color:green', e.response.resultStatus.ReturnId);
                        e.sender.options.async.removeUrl = "/Shared/DeleteFileUploaded.ashx?FileManagerId=" + e.response.resultStatus.ReturnId + "&Action=Agenda";
                        $("#hfFileManagerId").val(e.response.resultStatus.ReturnId);
                    }
                }
}
