我试过这个,但它也显示了Abu Dhabi
位置,这是迪拜。但我只想在Dubai
区域的地址。
var defaultBounds = new google.maps.LatLngBounds(
new google.maps.LatLng(25.1851804, 55.2780796) // Dubai area
);
var options = {
bounds: defaultBounds,
types: ['establishment'],
componentRestrictions: { country: 'AE' }
};
var autocomplete = new google.maps.places.Autocomplete(input, options);
Autocomplete唯一真正的选择是使用componentRestrictions到国家(就像您正在做的那样),然后使用strictBounds。
对于迪拜的边界,地理编码器返回边界和视口:{ north:25.3585607, east:55.5650393, south:24.7921359, west:54.8904543}
(自动完成 API 返回相同的视口,在place.geometry.viewport
中)。
Bounds from Google Geocoder (square) vs. Bounds from GADM (not square):

我认为在你的情况下,你需要传递中心参数,例如:
center: new google.maps.LatLng(25.1851804, 55.2780796),
的链接有一个很好的例子:
