使用getJSON的Google Maps V3地理编码查询

我有一个类似这里的问题:

I have a question similar to here:

结合使用jquery.getJson和Google的GeoCoding HTTP服务

除了我试图从客户端查找中不使用API​​密钥来检索地址的地理坐标之外.

with the exception that I'm trying to retrieve the geo-coordinates for an address without using the API key, from a client-side lookup.

使用此代码，一切似乎都能正常工作

Everything seems to work when using this code:

$.getJSON("http://maps.google.com/maps/api/geocode/json?address=202++3991+Henning+Dr+Burnaby+BC+V5C+6N5&sensor=false&callback=?",
  function(data, textStatus){
     console.log(data);
     console.log(textStatus);
});

但是，我收到了标签无效"的jQuery错误.

However, I'm getting an 'invalid label' jQuery error.
