Javascript 谷歌地图API加载动态信息窗口
我让谷歌地图从我的数据库在地图上动态加载位置。问题在于它没有在每个位置显示正确的显示信息。它只在所有标记上显示上一个产品的信息。我需要以某种方式遍历每个标记。我的代码如下:Javascript 谷歌地图API加载动态信息窗口,javascript,google-maps,symfony,google-maps-api-3,maps,Javascript,Google Maps,Symfony,Google Maps Api 3,Maps,我让谷歌地图从我的数据库在地图上动态加载位置。问题在于它没有在每个位置显示正确的显示信息。它只在所有标记上显示上一个产品的信息。我需要以某种方式遍历每个标记。我的代码如下: <section class="content jumbotron jumbotron-full-height"> <div class="item slide-1"> <div id="home-map"></div> </div>

问题在于您没有动态设置其内容。为此,必须从另一个函数创建标记
