融合表地图不显示

我将此代码保存为html文件，但我无法将地图可视化。我直接从FusionTablesLayer向导2.0中获取代码。代码有问题吗？我认为它会'准备好使用'。我需要一些帮助！融合表地图不显示

唯一缺少的东西是各地的编码表ID的报价:-)

function initialize() { 
     map = new google.maps.Map(document.getElementById('map-canvas'), { 
     center: new google.maps.LatLng(0, 0), 
     zoom: 1, 
     mapTypeId: google.maps.MapTypeId.ROADMAP 
     }); 
     layerl0 = new google.maps.FusionTablesLayer({ 
     query: { 
      select: "'geometry'", 
     from: "1x46BzbRzLVz2S4_ml5Nx4oto2930DFrH39TM3uc" 
    }, 
    map: map 
    }); 
} 

function changeMapl0() { 
    var searchString = document.getElementById('search-string-l0').value.replace(/'/g, "\\'"); 
    layerl0.setOptions({ 
    query: { 
     select: "'geometry'", 
     from: "1x46BzbRzLVz2S4_ml5Nx4oto2930DFrH39TM3uc", 
     where: "'NOME' = '" + searchString + "'" 
    } 
    }); 
}

我把你的代码上jsFiddle with my correction。

我的理解是，加密文档ID只适用于Fusion Table API，不适用于Fusion Tables API的Fusion Tables层。通过FT用户界面访问您的表格，然后选择文件 - >关于它将显示加密标识和数字标识。尝试使用，而不是加密ID数字ID：

layerl0 = new google.maps.FusionTablesLayer({ 
     query: { 
      select: "'geometry'", 
     from: 1x46BzbRzLVz2S4_ml5Nx4oto2930DFrH39TM3uc // change this to numeric id 
    },

这应该工作，但是我觉得很有道理，如果你用它在其他地方，切换到ENCID（也就是说，如果你使用的Fusion Tables API _and_ GMaps API）。 – Odi 2012-04-26 06:15:21

谢谢。我还没有意识到地图API支持encid – 2012-04-26 13:12:46
