My action method

Answer 1

Here is a working demo like below:

1.View(Index.cshtml):

<table id="datatable" class="display" style="width:100%">
    <thead>
        <tr>
            <th>id</th>
            <th>goodsName</th>
            <th>scale</th>
            <th>action</th>
        </tr>
    </thead>
    <tfoot>
        <tr>
            <th>id</th>
            <th>goodsName</th>
            <th>scale</th>
            <th>action</th>
        </tr>
    </tfoot>
</table>
@section Scripts{
<link rel="stylesheet" type="text/css" href="https://cdn.datatables.net/1.10.20/css/jquery.dataTables.css">
<script type="text/javascript" charset="utf8" src="https://cdn.datatables.net/1.10.20/js/jquery.dataTables.js"></script>
<script>
    $(document).ready(function () {
        $('#datatable').DataTable({
            ajax: {
                type: 'GET',
                dataType: 'JSON',
                url: '@Url.Action("GoodsList", "Home")'
            },
            columns: [
                { 'data': 'id' },
                { 'data': 'goodsName' },
                { 'data': 'scale' },
                {
                    'data': 'id',
                    'render': function (data) {
                        {
                            return '<a  href="#" title="ویرایش" style="margin-left:10px" class="btn btn-success button"  onclick="openModal(' + data + ');"><i class="fa fa-edit"></i></a><a  href="#" title="حذف" style="margin-right:10px"  class="btn btn-danger button"  onclick="deleteUser(' + data + ')"><i class="fa fa-trash"></i></a>'
                        }
                    },
                }
            ]
        })
    })
</script>
}

2.Controller:

public IActionResult Index()
{
    return View();
}
public IActionResult GoodsList()
{
    var goodsScale =  new List<object>
    {
        new {id = 1, goodsName= "aa",scale="a"},
        new {id = 2, goodsName= "bb",scale="b"},
        new {id = 3, goodsName= "cc",scale="c"},
        new {id = 4, goodsName= "dd",scale="d"} 
    };
    return Json(new { data=goodsScale });
}

3.Result(the url should be:/home/index):
