无法使用Google map javascript api v3在Google地图上设置多个标记 [英] Not able to set multiple markers on the Google maps using Google map javascript api v3

问题描述

我想在地图上放置多个标记，但我得到的地图没有设置标记。

i want to place multiple markers on the map but I'm getting a map with no markers set.

<script type="text/javascript">

  var map;
  var i;

  window.onload=function()
  {
    var mapOptions = {
      zoom: 13,
      mapTypeId: google.maps.MapTypeId.ROADMAP,
      center: new google.maps.LatLng(59.32522, 18.07002)
    };

    map = new google.maps.Map(document.getElementById("map"),mapOptions);
    var bounds = new google.maps.LatLngBounds();
         var places =[];
         places.push(google.maps.LatLng(40.756,-73.986));
         places.push(google.maps.LatLng(59.32522, 18.07002));
         places.push(google.maps.LatLng(37.775,-122.419));
         places.push(google.maps.LatLng(47.620,-122.347));
         places.push(google.maps.LatLng(-22.933,-43.184));
         for(i=0; i<places.length;i++)
      {
          var marker= new google.maps.Marker({position:places[i],map: map,title:'place Number'+i});

        bounds.extend(places[i]);

      }
      map.fitBounds(bounds);
  }
</script>

推荐答案

您需要更改所有看起来像这样的行：

You need to change all your lines that look like this:

     places.push(google.maps.LatLng(40.756,-73.986));

看起来像这样：

To look like this:

     places.push(new google.maps.LatLng(40.756,-73.986));

以上是您的代码，并进行了这些修改。它为我工作。尝试一下：

Here's your code above with these modifications. It's working for me. Try it:

<script type="text/javascript">

  var map;
  var i;

  window.onload=function()
  {
    var mapOptions = {
      zoom: 13,
      mapTypeId: google.maps.MapTypeId.ROADMAP,
      center: new google.maps.LatLng(59.32522, 18.07002)
    };

    map = new google.maps.Map(document.getElementById("map"),mapOptions);
    var bounds = new google.maps.LatLngBounds();
         var places =[];
         places.push(new google.maps.LatLng(40.756,-73.986));
         places.push(new google.maps.LatLng(59.32522, 18.07002));
         places.push(new google.maps.LatLng(37.775,-122.419));
         places.push(new google.maps.LatLng(47.620,-122.347));
         places.push(new google.maps.LatLng(-22.933,-43.184));
         for(i=0; i<places.length;i++)
      {
          var marker= new google.maps.Marker({position:places[i],map: map,title:'place Number'+i});

        bounds.extend(places[i]);

      }
      map.fitBounds(bounds);
  }
</script>
