jQuery getJSON在查询Google地图时返回null，即使结果有效

我似乎无法让这个简单的代码工作：

<script type="text/javascript">
$(document).ready(function(){ 
    $.getJSON('http://maps.google.com/maps/api/geocode/json?address=cebu&sensor=false&region=ph', 
    function(results) {
        alert(results);
    });
});
</script>

我还需要做什么？我已经反复阅读了jquery手册，但我似乎无法让这个简单的示例起作用

谢谢

第3段： “请注意，您尝试调用的站点需要支持JSON-P输出。”

您确定maps.google.com支持此功能吗

json-p

是

键（这很有诗意！）是的，它不支持json-p。在Stackoverflow中也发现了这一点：
