该示例来自谷歌地图文档，我发现它对我非常有用。我的问题是我无法在我的匿名函数中使用infoWindow内容，按钮调用该函数。我尝试了两种构造函数的方法，但我没有弄明白。提前谢谢^^

我的老师向我展示了如何做到的简单方法。

在体内你应该添加没有任何视觉效果的div。将标记设置为可见后，获取类.hidden-data，您可以为标记的每个属性添加任意数量的属性。

   <div class="hidden-data" data-place="" data-location="" data-address=""></div>
                marker.setVisible(true);

                $(".hidden-data").attr('data-place', place.name);
                $(".hidden-data").attr('data-location', place.geometry.location);
                $(".hidden-data").attr('data-address', place.formatted_address);

将在按钮单击时调用的jQuery函数应如下所示：

$("#addNewStore").click(function () {
    var a = $(".hidden-data").attr('data-place');
    var a = $(".hidden-data").attr('data-location');
    var a = $(".hidden-data").attr('data-address');
});
