Question

我正在尝试放置多个自定义标记，我想要的是放大并聚焦点击标记的位置。到目前为止，我已经部分成功，但有两个问题。首先，当我点击标记并放大地图时不断摇晃，第二个问题是我只能管理焦点在一个位置。即使我点击另一个，地图也会聚焦第一个。

当您在循环中有标记并想要访问所点击的标记时，请始终使用'this'而不是标记变量，

例如。

for(var i=0; i<9; i++) {
  new google.maps.event.addListener(markers[i], 'click', function() {
    infowindow.open(map, this)
  });
}

如果你不进行上述工作，而是使用标记变量，循环会在你点击标记之前执行并完成，因此I的值将始终是其最后一次迭代的值。因此点击只显示最新的
