如何将所选按钮显示为标签

Question

我有多年的纽扣。喜欢2018    2017    2016   2015我正在使用for循环将年份作为按钮。索引视图@model List<MyRecord.Models.RecordList>var year = DateTime.Now.Year;for (var i = year; i > 2012; i--){    var j = @i - 1;    <div class="col-md-1 ">        @Html.ActionLink(i.ToString(), "MyPage", new { i = i })    </div>}<h3>@ModelYear.Year</h3>@foreach (var groupMonth in Model.Records.GroupBy(recordLists => new { recordLists.date.Value.Year, recordLists.date.Value.Month })){    <h3 class="monthHeader"> @System.Globalization.CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(groupMonth.Key.Month)</h3>    foreach (var recordLists in groupMonth)    {        <div class="row">            @Html.Partial("_PartialView", recordList)        </div>    }}控制器public ActionResult Archives(int i = 0){    var recordLists = new List<RecordList>();    if(i == 0)        recordLists = _db.recordlists            .Where(p => p.date.Value.Year == DateTime.Now.Year)            .OrderByDescending(p => p.date)            .ToList();    else        recordLists = _db.recordlists            .Where(p => p.date.Value.Year == i)            .OrderByDescending(p => p.date)            .ToList();     return View(new ModelYear{Records = recordLists, Year = i});}模型：命名空间 MyRecord.Models{using System;using System.Collections.Generic;公共部分类 RecordList {    public int id { get; set; }    public string title { get; set; }    public Nullable<System.DateTime> date { get; set; }}public class ModelYear{    public int Year { get; set; }    public List<RecordList> Records { get; set; }}}当我点击任何一年时，我会根据月份显示该年的记录。我能够获得月份名称，而不是年份。我的问题是我需要将所选年份显示为标签或标题；如果我点击 2016，我应该会看到如下内容：**2016**Janrecord 1record 2如何显示点击的年份？

Answer 1

为什么不将它包含在 Model 类中：

public class Model

{

    public int Year {get;set;}

    public List<RecordList> Records {get;set;}

}

然后你可以在控制器中设置它：

public ActionResult Archives(int i = 0)

{

    var recordLists = new List<RecordList>();

      if(i == 0)

          recordLists = _db.recordlists.Where(p => p.date.Value.Year == DateTime.Now.Year)

                          .OrderByDescending(p => p.date).ToList();

      else{

          recordLists = _db.recordlists.Where(p => p.date.Value.Year == i).OrderByDescending(p => p.date).ToList();

      }

      return View(new Model{Records = recordLists, Year = i});

}

并将其显示在视图中：

<h1>@Model.Year</h1>

@foreach (var groupMonth in Model.Records.GroupBy(recordLists => new { recordLists.date.Value.Year, recordLists.date.Value.Month }))

        {

            <h3 class="monthHeader"> @System.Globalization.CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(groupMonth.Key.Month)</h3>

            foreach (var recordLists in groupMonth)

            {

                <div class="row">

                    @Html.Partial("_PartialView", recordList)

                </div>

            }

        }
