无标记加载Google地图

我有两个单选按钮。选中第一个时,我会显示一个谷歌地图,其中包含一些标记。我希望当我检查第二个radion按钮时,它会显示相同的地图,但没有标记。你能帮忙吗?

<div><input type="radio" name="reception" id="rad" value="livraison"> Livraison</div>
<div><input type="radio" name="reception" value="point"> Point de récuperation</div>

<div id="map" style=" display:none; height: 300px; border: 1px solid red;"></div>

<script type="text/javascript">
    window.onload=function(){


        var receps=document.querySelectorAll('[name=reception]');

        for (var i = 0; i < receps.length ; i++)
        {
            receps[i].onclick=function(e){

                if(e.target.value == 'livraison'){

                    document.getElementById('map').style.display  = 'block';
                }
                else{
                    //How to display the map without markers
                }

            }
        }

有地图api的回调函数:

function initMap() {

        var sp = {lat: 23.54565, lng: 11.453};
        var metro_a={lat:12.4545  , lng: 13.3148};
        var metro_n={lat:10.934329596  , lng: 10.323665372};
        var lieux=[
                    {
                        nom: "MT" ,
                        coordonnees:{lat: 11.93863, lng: 10.31413}
                    },
                    {
                        nom: "MA",
                        coordonnees:{lat:19.9361  , lng: 10.3148}
                    },
                    {
                        nom:"MN" ,
                        coordonnees:{lat:18.936  , lng: 10.323665372}
                    }
        ];

        var map = new google.maps.Map(document.getElementById('map'), {
          zoom: 14,
          center: sp
        });


        //--------------------------------------------------------------
        for (var i = 0; i < lieux.length; i++) {
            var marker= new google.maps.Marker({
                position:lieux[i].coordonnees,
                nom:lieux[i].nom,
                map:map
            });

        }

PS:我想在两台收音机之间切换。如果选中livraison,则会显示没有标记的地图。如果选中了点,则会显示带有标记的地图

如果所选单选按钮的值为“point”,则显示标记,否则不显示:

var point = document.querySelector('input[name = reception]:checked');
if (point && point.value == 'point') {
  var bounds = new google.maps.LatLngBounds();
  for (var i = 0; i < lieux.length; i++) {
    var marker = new google.maps.Marker({
      position: lieux[i].coordonnees,
      nom: lieux[i].nom,
      map: map
    });
    bounds.extend(marker.getPosition());
  }
  map.fitBounds(bounds);
}

在添加标记之前,查看选择了哪个单选按钮:

var selected = document.querySelector('input[name = "reception"]:checked').value;

if(selected === "livraison") {
    for (var i = 0; i < lieux.length; i++) {
        var marker= new google.maps.Marker({
            position:lieux[i].coordonnees,
            nom:lieux[i].nom,
            map:map
        });

    }
}
