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));
}
这是我从控制台得到的错误:
未捕获的TypeError:无法读取未定义的属性'sphere'
