我有这个 HTML 文件(如下)，它与此处找到的文件几乎相同。 https://developers.google.com/maps/documentation/javascript/examples/infowindow-simple
我遇到的问题是我认为任何脚本部分或 HTML 都没有任何问题，然后我再次作为志愿者为非营利组织编写此内容，并且我通常不会执行此 HTML 或 javascript 。该文件是由 perl 脚本生成的，所以请对我宽容一些。
请让我知道我做错了什么!

最佳答案
JavaScript 区分大小写。 new google.maps.Latlng(-77.675106,43.090076) 应该是 new google.maps.LatLng(-77.675106,43.090076) 和 document.getElementByID( 'map-canvas') 应为 document.getElementById('map-canvas')。就我个人而言，我不喜欢输入 google.maps 或使用 document.getElementById()，所以我这样做:
var doc = document, bod = document.body, gm = google.maps;
function E(e){
return doc.getElementById(e);
}
var myHome = new gm.LatLng(-77.675106,43.090076);
var canvas = E('map-canvas'); // same as document.getElementById('map-canvas');
