google.maps.geometry.spherical错误 [英] google.maps.geometry.spherical error

问题描述

我在使用谷歌地图上的几何图形时遇到了一些麻烦。我收到以下错误：
无法获取未定义或空引用的属性'spherical'。

I am having some troubles using the geometry at google maps. I am getting the following error: "Unable to get property 'spherical' of undefined or null reference."

这是w3c的一些代码， 。

This is some code from w3c with some additions of mine.

var x=new google.maps.LatLng(52.395715,4.888916);
var stavanger=new google.maps.LatLng(58.983991,5.734863);
var amsterdam=new google.maps.LatLng(52.395715,4.888916);
var london=new google.maps.LatLng(51.508742,-0.120850);
function initialize()
{
var mapProp = {
  center:x,
  zoom:4,
  mapTypeId:google.maps.MapTypeId.ROADMAP
};

var map=new google.maps.Map(document.getElementById("googleMap"),mapProp);
var myTrip=[stavanger,amsterdam,london];
var flightPath=new google.maps.Polyline({
    path:myTrip,
    strokeColor:"#0000FF",
    strokeOpacity:0.8,
    strokeWeight:2
    });
flightPath.setMap(map);

try{
    var markerpos = google.maps.geometry.spherical.interpolate(flightPath.getAt(0), flightPath.getAt(1), .5);
    // also tried //
    //var Spherical = google.maps.geometry.spherical;
    //var markerpos = Spherical.interpolate(flightPath.getAt(0), flightPath.getAt(1), .5);
    //var markerpos = google.maps.geometry.spherical.interpolate(amsterdam, london, .5);
}
catch(ex){alert(ex);}

var marker = new google.maps.Marker({position: markerpos,
    map: map,  clickable: false
});
}

上面的代码有什么问题？

What is wrong with the above code?

推荐答案

您是否正在加载正确的库与 libraries = 参数？

Are you loading the correct library with the libraries= parameter?

<script src="https://maps.googleapis.com/maps/api/js?v=3&sensor=false&libraries=geometry"></script>
