    change your onclick to this

    onclick='viewmap(this)'

    and get data with jquery like this

    function viewmap(elm){
  var id = $(elm).data('id');
  alert('id is ' + id);
}

    Pass this in onclick function and get in viewmap function and access
    You can try below code ..

    PHP

    <?php

echo "<td>"."<a class='map-pop' data-id='".$employee_time['id']."' data-toggle='modal' data-target='#mapModal' onclick='viewmap(this);'><img src='assets/viewmap.png'></a>"."</td>";
         
?>

    Script

    <script>
function viewmap(m)
{
     var ids = m.attr('data-id');
        alert('id is ' + ids);
}

</script>

    The problem is that you are using this inside your function viewmap but you are not sending it as a parameter from the HTML code, Change your onclick by: onclick='viewmap(this); than change the js function like bellow:

    function viewmap(e)
{
     var ids = $(e).attr('data-id');
     alert('id is ' + ids);
}
    <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<a class='map-pop' data-id='1254' data-toggle='modal' data-target='#mapModal' onclick='viewmap(this);'>
  click here
</a>

    Remove onclick attribute and change the viemap() function like this

    $(".map-pop").click(function(e) {
  e.preventDefault();
  
  let ids = $(this).data('id');
  alert(`id is ${ids}`);
});
    <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<a class='map-pop' data-id='".$employee_time['id']."' data-toggle='modal' data-target='#mapModal'><img src='assets/viewmap.png'></a>
