Question

我制作了按钮，每个按钮都指向地图上的某个位置，它工作正常，但不是很好但是有效，但当我尝试添加一个信息窗口时，它会出现在标记上，它不会＃＆＃ 39;工作，我不知道为什么！

Answer 1

您必须将信息窗口添加到地图对象

 google.maps.event.addListener(window, 'load', infowindow.open(map, marker));

Answer 2

这将打开标记上的信息窗口：

function addMarkerWithTimeout(position, timeout) {
  window.setTimeout(function() {
    var marker = new google.maps.Marker({
      position: position,
      map: map,
      animation: google.maps.Animation.DROP
    });
    google.maps.event.addListener(window, 'load', function(evt) {
      infowindow.open(map, marker));
    });
    markers.push(marker);
  }, timeout);
}

您只定义了一个具有固定内容的信息窗口，因此每个标记的信息都是相同的。
