Good Evening. I am working on home based project and new learner to the Laravel and coding.

@foreach ($totalmilkselldataforyeartotable as $item)

  <div class="col-md-4 col-sm-6 col-lg-2">
        <div class="card border-success " style="width: 12rem;">
            <div class="card-header">
              <span id="monthnameforcard"> <strong>{{ $item['monthname'] }}</strong>  </span> 
            </div>
              <ul class="list-group list-group-flush">
                <li class="list-group-item">Total Milk - &nbsp;<strong>{{ $item['totalmilk'] }}</strong></li>
                                                                
              </ul>

I suggest you use class instead of id and use closest to get the parent element that has card class then use querySelector to get the element has monthnameforcard class

@foreach ($totalmilkselldataforyeartotable as $item)

  <div class="col-md-4 col-sm-6 col-lg-2">
        <div class="card border-success " style="width: 12rem;">
            <div class="card-header">
              <span class="monthnameforcard"> <strong>{{ $item['monthname'] }}</strong>  </span> 
            </div>
              <ul class="list-group list-group-flush">
                <li class="list-group-item">Total Milk - &nbsp;<strong>{{ $item['totalmilk'] }}</strong></li>
                                                                
              </ul>
            <button type="button" class="btn btn-link">
                <span class='glyphicon glyphicon getmonthmilkdetails'> More <i class="fas fa-arrow-circle-right"></i> </span>
            </button>
        </div>

    </div>

@endforeach

$(document).on('click', '#getmonthmilkdetails', function(E) {

                    var getmonthnameforajax = e.currentTarget.closest('.card').querySelector('.monthnameforcard').textContent;
                    alert(getmonthnameforajax);

                    $.ajax({

                        type: 'post',
                        url: '/getmonthmilkdetails',
                        data: {
                            '_token'            : $('input[name=_token]').val(),
                            'monthname'         : getmonthnameforajax,
                        },

                        success: function(data) {

                                

                        }
                    });


                });
