javascript - 谷歌地图加载错误 "google"未定义

Question

好吧，我在加载 map 时遇到了问题，这部分会将“google”显示为未定义。

var polyline = [
    new Google.map.LatLng(3.032617, 101.376),
    new Google.map.LatLng(3.03255, 101.3759),
    new Google.map.LatLng(3.032467, 101.3758),
    new Google.map.LatLng(3.031867, 101.3753),
    new Google.map.LatLng(3.0318, 101.3753)
];

var polylineopts = {
  path: polyline,
  map: map,
  strokecolor: 'blue',
  strokeopacity: 1.6,
  strokeweight: 3,
  geodesic: true
};

var poly = new google.maps.Polyline(polylineopts);

Answer 1

我预计错误是“Google”未定义。 JavaScript 区分大小写。

应该是:

var polyline = [
    new google.maps.LatLng(3.032617, 101.376),
    new google.maps.LatLng(3.03255, 101.3759),
    new google.maps.LatLng(3.032467, 101.3758),
    new google.maps.LatLng(3.031867, 101.3753),
    new google.maps.LatLng(3.0318, 101.3753)
];

var polylineopts = {
  path: polyline,
  map: map,
  strokecolor: 'blue',
  strokeopacity: 1.6,
  strokeweight: 3,
  geodesic: true
};

var poly = new google.maps.Polyline(polylineopts);
