Question

感觉我正在失去理智，因为我不知道我错过了什么。我正在尝试复制https://developers.google.com/fusiontables/docs/samples/search_and_zoom中使用的示例，与该表格上的表格完全相同，用于Fusion Table ID 1IYJMddMoWgwjieq3rwh8YyiHVpZy_1--hoNrPPa2

给出的代码是：

  function initialize() {
    var defaultCenter = new google.maps.LatLng(10, 10);
    var defaultZoom = 2;
    var tableId = '1ZU8D1ASYZMeIise2gboBt-HPt9hX8Y2NIdMfZg';

          // OPTIONAL: run spatial query to find results within bounds.

          var where = 'ST_INTERSECTS(' + locationColumn +

          layer.setOptions({
            query: {
              select: locationColumn,
              from: tableId,
              where: where
            }

    google.maps.event.addDomListener(document.getElementById('search'),

         google.maps.event.addDomListener(window, 'keypress', function(e) {
           if (e.keyCode == 13) {
             zoomToAddress();
           }
         });
         google.maps.event.addDomListener(document.getElementById('reset'),

               map.setCenter(defaultCenter);
               map.setZoom(defaultZoom);

                 query: {
                   select: locationColumn,
                   from: tableId
                 }
               });
             });
       }

       google.maps.event.addDomListener(window, 'load', initialize);

     </script>
   </head>
   <body>
     <div id="map-canvas"></div>
     <div>
       <label>Enter an address:</label>
       <input type="text" id="address" value="Mountain View, CA">
       <input type="button" id="search" value="Search!">
       <input type="button" id="reset" value="Reset">
     </div>
   </body>

我真的只是替换了：

 var defaultCenter = new google.maps.LatLng(10, 10);
 var defaultZoom = 2;
 var tableId = '1ZU8D1ASYZMeIise2gboBt-HPt9hX8Y2NIdMfZg';
 var locationColumn = 'lat';

使用：

 var defaultCenter = new google.maps.LatLng(-33.927758210970154, 150.95845901699215);
 var defaultZoom = 10;
 var tableId = '1IYJMddMoWgwjieq3rwh8YyiHVpZy_1--hoNrPPa2';
 var locationColumn = 'col3';

我认为它会起作用，但地图本身不会显示。然后我想我会使用示例代码并测试它而不更改它但它也不会工作。

我错过了什么？！完全不知道我做错了什么。

Answer 1

可能未加载包含的样式表（路径仅在文档位于google-developers.appspot.com时有效），因此#map-canvas没有高度。

通过https://google-developers.appspot.com/fusiontables/docs/samples/style/default.css

指定高度或加载样式表

Fusion Tables搜索和缩放
