Question

您好，我是ASP NET的初学者，我被要求隐藏＆＃34;注册向导＆＃34;小组在特定日期之前和之后的2周。我相信我们正在使用JSon来显示面板。我不确定如何实现这一点，因为无法找到任何东西。

    module PrestigeWorldWide.Scripts.ViewModels {
    export class IndexViewModel extends BaseViewModels.BaseViewModel {
        public panels: KnockoutObservableArray<IPanelObject> = ko.observableArray<IPanelObject>();
        public events: KnockoutObservableArray<FullCalendar.EventObject> = ko.observableArray<any>();

        constructor() {
            super();


            this.panels.push({
                Name: "My Transcript",
                Desc: "View your unofficial QUB transcript",
                Icon: "fa-file-text",
                Link: "/PrestigeWorldwide/Grade/ViewTranscript"
            });

            this.panels.push({
                Name: "Module Info",
                Desc: "View the information on all modules including pre-requisites and course content",
                Icon: "fa-folder-open",
                Link: "/PrestigeWorldwide/Module/ModuleInfo"
            });

            this.panels.push({
                Name: "Enrollment Wizard",
                Desc: "Enroll for modules and enter further information about yourself - emergency contacts etc.",
                Icon: "fa-magic",
                Link: "/PrestigeWorldwide/Registration/Index"
            });

            this.getEvents();
        }

        getEvents() {
            var url = "/PrestigeWorldwide/Class/GetStudentClasses";
            this.loading(true);
            $.ajax(url).done((events: FullCalendar.EventObject[]) => {
                this.loading(false);
                _.each(events, (event) => {
                    this.events.push(event);
                });
            });
        }


    }

    export interface IPanelObject {
        Name: string;
        Desc: string;
        Icon: string;
        Link?: string;
    }
}

只需在添加面板之前添加日期检查：

DateTime cutOffDateStart = new DateTime() // Insert 2 weeks before here
DateTime cutOffDateEnd = new DateTime() // Insert 2 weeks after here

if (DateTime.Now >= cutOffDateStart && DateTime.Now < cutOffDateEnd) 
{
    panels.Add(new Panel()
    {
        Name = "Registration Wizard",
        Desc = "Use this tool to enrol for the new semester.",
        Icon = "fa-pencil"
    });
}

如何在某些日期隐藏json面板
