Question

我正在使用Google maps API来显示多个可以正常使用的位置。我添加了一个链接，我想用它来点击相应链接时的位置。

我添加了onclick以居中到该位置，但它无法正常工作

<a id="1" href="#">Go to 1</a><br>
<a id="2" href="#">Go to 2</a><br>
<a id="3" href="#">Go to 3</a><br>
<a id="4" href="#">Go to 4</a><br>
<a id="5" href="#">Go to 5</a><br>

var labels = '123456';
var labelIndex = 0;

var locations = [
  ['Bondi Beach', -33.890542, 151.274856, 4],
  ['Coogee Beach', -33.923036, 151.259052, 5],
  ['Cronulla Beach', -34.028249, 151.157507, 3],
  ['Manly Beach', -33.80010128657071, 151.28747820854187, 2],
  ['Maroubra Beach', -33.950198, 151.259302, 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,
    label: labels[labelIndex++ % labels.length],

  });
};

$("a").click(function(){
//zoom in on location

  var id = ($(this).data('id'));
   google.maps.event.trigger(id , "resize");
   map.panTo(marker.getPosition());
   map.setZoom(14);
  return false;
});

Answer 1

我已在JSFiddle中更新您的代码：http://jsfiddle.net/3gz43tqq/3/

$("a").click(function(){
    var id = this.id;
    map.setCenter(new google.maps.LatLng(locations[id][1], locations[id][2]))
    return false;
});

您可以从 a 使用功能 setCenter（LatLng对象）

获取ID
