Question

嘿伙计们能帮助我解决这个问题吗？我使用谷歌地图，问题是当我选择不同的选择选项时标记不会改变。我只是希望能够选择不同的位置数组，并且必须立即显示。

这是我的代码：

<!DOCTYPE html>
<html> 
<head> 
  <meta http-equiv="content-type" content="text/html; charset=UTF-8" /> 
  <title>Google Maps Multiple Markers</title> 
  <script src="http://maps.google.com/maps/api/js?sensor=false" 
          type="text/javascript"></script>
</head> 
<body>
  <div id="map" style="width: 500px; height: 400px;"></div>
  <select id="location">
  <option>locations1</option>
 <option>locations2</option>
 </select>

  <script type="text/javascript">

$('location').change(function(){

var location = $('location').val();

if(location == "locations1"){
 var locations = [
      ['Z Beach', -33.890542, 151.274856, 4],
      ['Y Beach', -33.923036, 151.259052, 5],
      ['X Beach', -34.028249, 151.157507, 3],
      ['T Beach', -33.80010128657071, 151.28747820854187, 2],
      ['V', -33.950198, 151.259302, 1]
    ];
}

if(location == "locations2"){
 var locations = [
      ['C Beach', -20.890542, 140.274856, 4],
      ['B Beach', -20.923036,140.259052, 5],
      ['E Beach', -20.028249, 140.157507, 3],
      ['A Beach', -20.80010128657071, 140.28747820854187, 2],
      ['C Beach', -20.950198, 140.259302, 1]
    ];
}


})


    var map = new google.maps.Map(document.getElementById('map'), {
      zoom: 10,
      center: new google.maps.LatLng(-33.92, 151.25),
      mapTypeId: google.maps.MapTypeId.ROADMAP
    });

    var infowindow = new google.maps.InfoWindow();

    var marker, i;

    for (i = 0; i < locations.length; i++) {  
      marker = new google.maps.Marker({
        position: new google.maps.LatLng(locations[i][1], locations[i][2]),
        map: map
      });

      google.maps.event.addListener(marker, 'click', (function(marker, i) {
        return function() {
          infowindow.setContent(locations[i][0]);
          infowindow.open(map, marker);
        }
      })(marker, i));
    }
  </script>
</body>
</html>
