我可以设法在地图上显示我的图像叠加层。但是出现了一个新问题 - 我无法在其上添加标记。我用谷歌搜索了一段时间，但没有运气。试图搜索和模仿文档中的示例，但似乎没有什么是正确的。

这是我的代码：

<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>
<script>
    function initialize() {
      var newark = new google.maps.LatLng(xx.xxxxx,xx.xxxxx);
      var imageBounds = new google.maps.LatLngBounds(
          new google.maps.LatLng(xx.xxxxx,xx.xxxxx),//SW
          new google.maps.LatLng(xx.xxxxx,xx.xxxxx)//NE
        );

      var mapOptions = {
        zoom: 20,
        center: newark,
        mapTypeId: google.maps.MapTypeId.ROADMAP
      }

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

      var oldmap = new google.maps.GroundOverlay(
          'images/floor_plan_trans_rotated.gif',
          imageBounds);
      oldmap.setMap(map);
    }

    /*markers*/
      var contentString = '<div id="content">'+
          '<div id="siteNotice">'+
          '</div>'+
          '<h1 id="firstHeading" class="firstHeading">Uluru</h1>'+
          '<div id="bodyContent">'+
          '<p><b>Uluru</b>, also referred to as <b>Ayers Rock</b>, is a large ' +
          'sandstone rock formation in the southern part of the '+
          'Northern Territory, central Australia. It lies 335&#160;km (208&#160;mi) '+
          'south west of the nearest large town, Alice Springs; 450&#160;km '+

</p>'+
      '<p>Attribution: Uluru, <a href="http://en.wikipedia.org/w/index.php?title=Uluru&oldid=297882194">'+
      'http://en.wikipedia.org/w/index.php?title=Uluru</a> '+
      '(last visited June 22, 2009).</p>'+
      '</div>'+
      '</div>';

  var infowindow = new google.maps.InfoWindow({
      content: contentString,
      maxWidth: 400
  });

  var marker = new google.maps.Marker({
      position: newark,
      map: map,
      title: 'Uluru (Ayers Rock)'
  });
  google.maps.event.addListener(marker, 'click', function() {
    infowindow.open(map,marker);
  });
}

/*markers*/
google.maps.event.addDomListener(window, 'load', initialize);
    </script>
<div id="map-canvas"></div>

对于上面的代码。除非我删除 /标记/之间的那些线，否则地图不会显示。

请建议。问候，

在这段代码的第一个 /标记/上方没有额外的 }吗？或者我只是困了......

我正在做类似的事情并且它正在工作，在同一张地图上使用groundOverlay和marker

有几件事在您的代码中放错了位置。

  1. </p> 之前缺少单引号 (')
  2. 提前关闭初始化函数大括号（}）

休息一切似乎都很好。我更正了这些，这是完整的代码。

<script>
    function initialize() {
        var newark = new google.maps.LatLng(xx.xxxxx,xx.xxxxx);
        var imageBounds = new google.maps.LatLngBounds(
            new google.maps.LatLng(xx.xxxxx,xx.xxxxx),//SW
            new google.maps.LatLng(xx.xxxxx,xx.xxxxx)//NE
        );

        var mapOptions = {
            zoom: 18,
            center: newark,
            mapTypeId: google.maps.MapTypeId.ROADMAP
        }

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

        var oldmap = new google.maps.GroundOverlay(
            'images/floor_plan_trans_rotated.gif', imageBounds);
        oldmap.setMap(map);

        /*markers*/
        var contentString = '<div id="content">'+
            '<div id="siteNotice">'+
            '</div>'+
            '<h1 id="firstHeading" class="firstHeading">Uluru</h1>'+
            '<div id="bodyContent">'+
            '<p><b>Uluru</b>, also referred to as <b>Ayers Rock</b>, is a large ' +
            'sandstone rock formation in the southern part of the '+
            'Northern Territory, central Australia. It lies 335&#160;km (208&#160;mi) '+
            'south west of the nearest large town, Alice Springs; 450&#160;km '+
            '</p>'+
            '<p>Attribution: Uluru, <a href="http://en.wikipedia.org/w/index.php?title=Uluru&oldid=297882194">'+
            'http://en.wikipedia.org/w/index.php?title=Uluru</a> '+
            '(last visited June 22, 2009).</p>'+
            '</div>'+
            '</div>';

        var infowindow = new google.maps.InfoWindow({
            content: contentString,
            maxWidth: 400
        });

        var marker = new google.maps.Marker({
            position: newark,
            map: map,
            title: 'Uluru (Ayers Rock)'
        });

        google.maps.event.addListener(marker, 'click', function() {
            infowindow.open(map,marker);
        });
    }

    /*markers*/
    google.maps.event.addDomListener(window, 'load', initialize);
</script>
