使用地理编码器使地址成为谷歌地图的中心 [英] Using Geocoder to make an address the center of a google map
本文介绍了使用地理编码器使地址成为谷歌地图的中心的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我试图编写一个程序,查找地址的相应值latLng,然后将其用于地图的中心。这里是我的代码到目前为止,但我遇到的主要问题是从geocoder获取返回值。

};
var geocoder = new google.maps.Geocoder();
var address ='3410美国北卡罗来纳州新伯尔尼的Martin Luther King Jr Blvd博士';
$ b geocoder.geocode({'address':address},function(results,status){
if(status == google.maps.GeocoderStatus.OK)
{
var bounds = new google.maps.LatLngBounds();
document.write(bounds.extend(results [0] .geometry.location));
map.fitBounds( (
position:results [0] .geometry.location,
map:map
}
);
}
}
);
var map = new google.maps.Map(document.getElementById(map),mapOptions);

解决方案
您想设置Google地图对象的边界。
var bounds = new google.maps.LatLngBounds();
bounds.extend(results [0] .geometry.location);
map.fitBounds(bounds);
有关 LatLngBounds
optionaly你可以做 map.fitBounds (bounds.getCenter())
,如果在 LatLngBounds
中有多个 latlng
I'm trying to write a program that finds the respective values latLng for an address and then using that for the center of the map. Here is my code so far, however the main problem I am having is getting the values of back from the geocoder.

var bounds = new google.maps.LatLngBounds();

map.fitBounds(bounds);
new google.maps.Marker(

}
}
);
var map = new google.maps.Map(document.getElementById("map"), mapOptions);

解决方案
you want to set the bounds on the google map object.
var bounds = new google.maps.LatLngBounds();
bounds.extend(results[0].geometry.location);
map.fitBounds(bounds);
more info on LatLngBounds
optionaly you could do map.fitBounds(bounds.getCenter())
if you have more than one latlng
in the LatLngBounds
