如何根据所选单选按钮传递单选按钮值？

Question

我的视图中有以下单选按钮。如何传递所选单选按钮的值和数组索引中小于所选单选按钮的值？

 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 生成的代码

<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>

我的模型

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

我的操作收到

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

我的单选按钮如下所示

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

您可以给所有 .row div 一些 outer div 。然后，每当单击提交按钮时，首先使用此获取 checked 单选按钮值，我们将获得选中单选按钮的 div 的 index() 编号。最后，使用 for-loop 从其他单选按钮获取值并将它们推入 array 并使用 ajax.

传递相同的值

演示代码 :

$("#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")
    }
  });

})

<!--only add this outer div-->
<div class="outer">
  <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>
      202008
   </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 class="row">

      <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>
