如何根據選定的單選按鈕值傳遞單選按鈕值？

Question

我的視圖中有以下單選按鈕。 如何傳遞所選單選按鈕的值和數組索引中小於所選單選按鈕的值？

 foreach (var record in Model.Months.Select(x=>$"{x.Substring(4,2)}/{x.Substring(0,4)}").OrderByDescending(x=>x))
    {
         <div class="radio col-12">
            <div class="row">
              <div class="col-5" style="">
                @Html.RadioButton("MonthsAvailable", record, true, new { id = record, @class = "m-r" })<label>@record</label>
               </div>
             </div>
          </div>
    }

HTML 生成代碼

<div class="row">
   <label class="form-check-inline p-l-md m-b-sm m-r-md">
      <input class="hidden-up pos-abs monthsAvailable" id="082020" name="MonthsAvailable" type="radio" value="202008" checked="checked">
      <div class="check-icon-radio"><i></i></div>
      082020
   </label>
</div>
<div class="row">
   <label class="form-check-inline p-l-md m-b-sm m-r-md">
      <input class="hidden-up pos-abs monthsAvailable" id="092020" name="MonthsAvailable" type="radio" value="092020">
      <div class="check-icon-radio"><i></i></div>
      092020
   </label>
</div>

我的 Model

 public class MonthsAvailable
   {
    public List<string> Months{ get; set; }       
   }

我的行動收到

public async Task<IActionResult> MonthsAvailable(List<string> monthsAvailable)
 {
 ...
 }

我的單選按鈕如下所示

我正在努力完成

When I select 062020 pass only 062020 to the controller, 
When I select 072020 pass 062020 and 072020, 
when I select 082020 pass 062020, 072020 and  082020
when I select 092020 pass 062020, 072020, 082020 and 092020 and etc

您可以為所有.row div 提供一些outer div。 然后，每當單擊提交按鈕時，首先使用它獲取checked的單選按鈕值，我們將獲得選中單選的 div 的index()編號。 最后，使用for-loop從其他單選按鈕獲取值並將它們推入array並使用 ajax 傳遞相同的值。

演示代碼：

 $("#save").on("click", function() { var checked_value = []; //declare this var value = $("input[name=MonthsAvailable]:checked").val() //get value of checked checkboxs var lengths = $("input[value=" + value + "]").closest(".row").index() //get index console.log($("input[value=" + value + "]").closest(".row").index()) //loop for (var i = 0; i <= lengths; i++) { checked_value.push($(".outer.row:eq(" + i + ") input:radio").val()) //push value inside array } console.log(JSON.stringify(checked_value)) //ajax call $.ajax({ contentType: 'application/json; charset=utf-8', type: 'POST', url: 'yoururl', data: JSON.stringify(checked_value), success: function(data) { console.log("done") } }); })

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <!--only add this outer div--> <div class="outer"> <div class="row"> <label class="form-check-inline pl-md mb-sm mr-md"> <input class="hidden-up pos-abs monthsAvailable" id="082020" name="MonthsAvailable" type="radio" value="202008" checked="checked"> <div class="check-icon-radio"><i></i></div> 202008 </label> </div> <div class="row"> <label class="form-check-inline pl-md mb-sm mr-md"> <input class="hidden-up pos-abs monthsAvailable" id="092020" name="MonthsAvailable" type="radio" value="092020"> <div class="check-icon-radio"><i></i></div> 092020 </label> </div> <div class="row"> <label class="form-check-inline pl-md mb-sm mr-md"> <input class="hidden-up pos-abs monthsAvailable" id="082020" name="MonthsAvailable" type="radio" value="2020018" checked="checked"> <div class="check-icon-radio"><i></i></div> 2020018 </label> </div> <div class="row"> <label class="form-check-inline pl-md mb-sm mr-md"> <input class="hidden-up pos-abs monthsAvailable" id="092020" name="MonthsAvailable" type="radio" value="0920202"> <div class="check-icon-radio"><i></i></div> 0920202 </label> </div> </div> <button type="button" id="save">Save</button>
