Question

我有这个HTML文件（如下所示）几乎与此处找到的相同。 https://developers.google.com/maps/documentation/javascript/examples/infowindow-simple

我遇到的问题是，我发现任何脚本部分或HTML都没有错，然后我再次为非营利组织写这个作为志愿者而且我不是通常做这个HTML或JavaScript。这个文件是由perl脚本生成的，所以请对我很轻松。

请让我知道我做错了什么！

Answer 1

JavaScript区分大小写。 new google.maps.Latlng(-77.675106,43.090076)应为new google.maps.LatLng(-77.675106,43.090076)，document.getElementByID('map-canvas')应为document.getElementById('map-canvas')。就个人而言，我不想输入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');
