Question

我知道有很多相同的问题都有答案，但我似乎无法解决我的问题。

我使用的代码：

$.getJSON("http://maps.googleapis.com/maps/api/geocode/json?latlng=" + results[0].geometry.location.lat() + "," + results[0].geometry.location.lng() + "&sensor=false&callback=?", function (data) {
    if (data[0]) {
        alert(data[0].formatted_address);
    }
});

当我转到网址但不在我的应用程序中时，我可以获得json结果。如果我删除&callback=?我得到XmlHttpRequest错误，但如果我这样做，我会得到标题错误。我从一些答案中读到，我实际上应该期待一个json的格式如（{json-content}）而不是{json-content}。如果是这样，我如何获得正确的格式？

此api上对JSONP的支持已被删除 - 这意味着它返回JSON而不是JSONP - 这就是您收到该错误的原因

Duplicate answer here gives a good alternative或类似的东西：

<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">

var geocoder = new google.maps.Geocoder();
var latlong = new google.maps.LatLng("37.5097258429375","-122.27783203125");

geocoder.geocode({
    'latLng': latlong
}, function(results, status) {

    if (status == google.maps.GeocoderStatus.OK) {
        alert(results[0].formatted_address);
    }
});
