How to get the lat & lng as separate variables from mapCenter
提问by Sebastian
I have the map center, and comes as a Floating Point number.
我有地图中心,并以浮点数形式出现。
How can I get it as 2 separated variables like this:
我怎样才能将它作为 2 个单独的变量,如下所示:
var lat = ...
var lng = ...
I have the float:
我有浮动:
var NewMapCenter = map.getCenter();
I tried to pass the float toWords(x)
but didn't work
我试图通过浮动toWords(x)
但没有用
I tried to subtract the (,)
and split
it, but didn't work
我试图减去(,)
和split
,但没有奏效
var latlngStr = (StrNewMapCenter.substr(1, (StrNewMapCenter.length-1))).split(",",2);
var NewMapCenter = parseFloat(latlngStr[0]);
I tried, this but comes as an event, but I need it without needing to click.
我试过了,但这只是一个事件,但我不需要点击就需要它。
google.maps.event.addListener(map, 'click', function(event) {
var myLatLng = event.latlng;
var Newlat = position.coords.latitude;
var Newlng = position.coords.longitude;
}
Thanks Sebastian
谢谢塞巴斯蒂安

var NewMapCenter = map.getCenter();
will give you LatLng object, so you can call
会给你 LatLng 对象,所以你可以打电话
var latitude = NewMapCenter.lat();
var longitude = NewMapCenter.lng();
