谷歌地图错误 - a.lng不是一个功能
Sur*_*esh 5 javascript google-maps
我打算在我的一个应用程序中使用谷歌地图"containsLocation()"API.文档链接是 - https://goo.gl/4BFHCz
我正在遵循相同的例子.这是我的代码.

如果你看到我创建了一个curPosition包含latLng数据的变量.我在这里的问题是只要var curPosition = e.latLng;它工作正常但是,我改变var curPosition = {"lat":12.9629277,"lng":77.7178972};它的那一刻开始显示错误"Uncaught TypeError: a.lng is not a function".
无法理解为什么会这样？任何线索......？
附加了Console.log屏幕截图
问候
该containsLocation方法需要google.maps.LatLng作为"点"(至少目前),你不能使用google.maps.LatLngLiteral currentLocation.
从文件:
containsLocation(point:LatLng,polygon:Polygon)| 返回值:布尔值
计算给定点是否位于指定的多边形内.
var curPosition = new google.maps.LatLng(12.9629277,77.7178972);
代码段:
function initMap() {
var map = new google.maps.Map(document.getElementById('map'), {
center: {
lat: 12.9629277,
lng: 77.7178972
},
zoom: 30,
});
var triangleCoords = [
{lat: 12.96301273,lng: 77.71785952}, {lat: 12.96314857, lng: 77.71784072}, {lat: 12.96316124, lng: 77.71784037}, {lat: 12.96293329, lng: 77.7179345}, {lat: 12.96295465, lng: 77.71788993}];
var bermudaTriangle = new google.maps.Polygon({
paths: triangleCoords,
map: map
});
var curPosition = new google.maps.LatLng(12.9629277, 77.7178972);
console.log("curPosition content : " + JSON.stringify(curPosition));
var resultColor =
google.maps.geometry.poly.containsLocation(curPosition, bermudaTriangle) ?
'red' :
'green';
new google.maps.Marker({
position: curPosition,
map: map,
icon: {
path: google.maps.SymbolPath.CIRCLE,
fillColor: resultColor,
fillOpacity: .2,
strokeColor: 'white',
strokeWeight: .5,
scale: 10
}
});
var curPositionB = new google.maps.LatLng(12.963, 77.71788993);
var resultColorB = google.maps.geometry.poly.containsLocation(curPositionB, bermudaTriangle) ?
'red' :
'green';
new google.maps.Marker({
position: curPositionB,
map: map,
icon: {
path: google.maps.SymbolPath.CIRCLE,
fillColor: resultColorB,
fillOpacity: .2,
strokeColor: 'white',
strokeWeight: .5,
scale: 10
}
});
