Question

在谷歌地图中，我想要隐藏和显示地图标记的按钮，但我需要有多个按钮，每个按钮都有自己的一组标记。例如，按钮1将显示和隐藏标记1和3，而按钮2将显示和隐藏标记2和4.

这对我来说有点困难，因为我是api v3的新手。

这是我的代码。

  function initialize() {

    var mapDiv = document.getElementById('map-canvas');
    var map = new google.maps.Map(mapDiv, {
      center: new google.maps.LatLng(-8.762472, -63.887951),
      zoom: 13,
      mapTypeId: google.maps.MapTypeId.ROADMAP       });


  var marker = new google.maps.Marker({
      map: map,
      position: new google.maps.LatLng(-8.759662,-63.906489),      
      icon:  predio});


   var infowindow    =  new google.maps.InfoWindow({
  content:contentimage})
 google.maps.event.addListener(marker,'click',function(){
infowindow.open(map,marker); });


var marker1 = new google.maps.Marker({
      map: map,
      position: new google.maps.LatLng(-8.766159,-63.889567),      
      icon:  yellow});


  var infowindow1    =  new google.maps.InfoWindow({
 content:contentimage1})
   google.maps.event.addListener(marker1,'click',function(){
infowindow1.open(map,marker1); });
}

            markers[0].setVisible(true);
            markers[1].setVisible(true);  
        }    
    });

    var btn2=document.getElementById('btn2'); 
    google.maps.event.addDomListener(btn2, 'click', function(){
