Distance between two locations - Google Maps
提问by cclerv
I'm trying to find the location between two points using google maps. Here is the code that I'm working with:
我正在尝试使用谷歌地图找到两点之间的位置。这是我正在使用的代码：
function initialize() {
var myOptions = {
center: new google.maps.LatLng(36.8813329,-103.6975488),
zoom: 4,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map-canvas"), myOptions);
var impactCoordinates = [
new google.maps.LatLng(37.772323, -122.214897),
new google.maps.LatLng(34.1633766,-81.6487862),
];
var ImpactPath = new google.maps.Polyline({
path: impactCoordinates,
strokeColor: "#FF0000",
strokeOpacity: 1.0,
strokeWeight: 2
});
ImpactPath.setMap(map);
var loc1 = new google.maps.LatLng(37.772323, -122.214897);
var loc2 = new google.maps.LatLng(34.1633766,-81.6487862);
alert(google.maps.geometry.spherical.computeDistanceBetween(loc1, loc2));
}
This is the error I get from the console:
这是我从控制台得到的错误：
Uncaught TypeError: Cannot read property 'spherical' of undefined
未捕获的类型错误：无法读取未定义的属性“球形”

If you haven't done so, explicitly add the geometry library in your <script>tag
src="http://maps.googleapis.com/maps/api/js?libraries=geometry&sensor=false">
如果您还没有这样做，请在您的<script>标签中
明确添加几何库src="http://maps.googleapis.com/maps/api/js?libraries=geometry&sensor=false">
