Use bootstrap dynamic modal for delete confirmation (laravel blade)

Assuming id field as Primary key of your table.
First replace your Laravel Blade Template Part with below code::

@foreach($dividends_10 as $_dividend_data)
<tr>
  <td>{{Portfolio\StockModel::select('short_name')->where('id',$_dividend_data['stock_id'])->value('short_name')}}</td>
  <td>{{$_dividend_data['amount']}}</td>
  <td>{{$_dividend_data['date']}}</td>
  <td><a href="{{'dividends'}}">Edit</a></td>
  <td><a href="{{'#'}}" class="delete-mdoal" data-value="{{$_dividend_data['id']}}" data-toggle="modal" data-target="#myModal">Delete</a></td>
</tr>
@endforeach

After that use below jQuery to made delete button value dynamic:

$(document).ready(function (e) {
    $(document).on("click", ".delete-mdoal", function (e) {
        var delete_id = $(this).attr('data-value');
        $('button[name="delete_dividend"]').val(delete_id);
    });
});
