我在谷歌地图上使用几何时遇到了一些麻烦。我收到以下错误:“无法获取未定义或空引用的属性‘球形’。”
这是来自 w3c 的一些代码以及我的一些补充。
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?
