似乎无法在Google地图上获得标记点击以执行任何操作

我有一个简单的谷歌地图专长我正在努力并且未能完成。

目前,我可以显示我的地图,然后通过PHP循环浏览项目列表(我正在使用ExpressionEngine),并将每个项目的纬度/经度添加到JavaScript数组中。

一旦值在JavaScript数组中,我使用jQuery循环遍历每个值,并向地图添加标记。

我可以点击地图并让它做出适当的回应;但是,当我试图点击其中一个标记时,根本没有任何事情发生。

我已经尝试过无休止地移动代码,重命名,更改,编辑和调整......我无法理解这一点。任何帮助都将非常感激。我的代码如下:

<script>

  // Create the new map_locations array
  var map_locations = [];

</script>



<!-- The following ExpressionEngine script loops through all the 'projects' on the site,
     then pushes each project to the map_locations array. -->
{exp:channel:entries channel="projects"}

  <script>


    map_locations.push( ['{url_title}', '{project_latitude}', '{project_longitude}', '{categories}{category_name}{/categories}', '{title}'] );


  </script>

{/exp:channel:entries}



<script>


var marker;


function initialize() {

   // To add the marker to the map, use the 'map' property
  var mapOptions = {

      center: { lat: 51.884 , lng: -95.147 },
      zoom: 4

  };

  var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);


  // Create a new location lat/long var, newLatLng
  var newLatLng;




  var contentString = "<div id='info_window'>this is the info window</div>"


  var infowindow = new google.maps.InfoWindow({

    content: contentString

  });



  var iconBase = '/images/map_icon_';



  $.each( map_locations, function()
  {

    newLatLng = new google.maps.LatLng( this[1] , this[2] );

    marker = new google.maps.Marker({

      position: newLatLng,
      map: map,
      title: this[4],
      icon: iconBase + this[3]

    });

  });



  google.maps.event.addListener(marker, 'click', function() {

    console.log( "This marker's url_title is: " + this[0] );

  });

  google.maps.event.addListener(map, 'click', function() {

    console.log( "Testing map click" );

  });



}



// Initialize the map
google.maps.event.addDomListener(window, 'load', initialize);



</script>

您试图在定义marker的循环之后为循环添加事件侦听器而不是在循环中

尝试:

   $.each( map_locations, function(){  

    var newLatLng = new google.maps.LatLng( this[1] , this[2] );

    var marker = new google.maps.Marker({

      position: newLatLng,
      map: map,
      title: this[4],
      icon: iconBase + this[3]

    });
     google.maps.event.addListener(marker, 'click', function(marker) {
        console.log( "This marker's url_title is: " + marker.title );
     });

  });
