单击谷歌地图中的标记添加信息窗口

Question

i am using PHP and MYSQL in order to retrieve data from the database and display markers on Google Map API with adding a info windows that includes info retrieved from the database using click-Listener. 我正在使用PHP和MYSQL，以便从数据库中检索数据并在Google Map API上显示标记，并添加一个信息窗口，其中包括使用click-Listener从数据库中检索到的信息。 after i added the info window it doesn't seems it works . 在我添加了信息窗口后，它似乎没有用。

           <div class="map-popupstring hidden" id="popupstring1">
                <div class="text-center">
                    <h3>title</h3>
                     <p>subinfo</p>
                </div>
            </div>

you must put in the wanted popup in html tags. 您必须在html标记中放入所需的弹出窗口。 and an code in the google maps tags to initialise it. 以及Google Maps标签中的代码对其进行初始化。 and use the data-popupstring-id="#popupstring1" tag to initialise it onclicking the markers. 并使用data-popupstring-id="#popupstring1"标签在data-popupstring-id="#popupstring1"标记时对其进行初始化。

var $popup = $("#popupstring1")

function addMarker(feature) {
      var marker = new google.maps.Marker({
        position: feature.position,
        data-popupstring-id: $popup,
        map: map
      });
    }

i solved the question by adding this code : 我通过添加以下代码解决了这个问题：

code: 码：

 var popup = new google.maps.InfoWindow({
                    content: feature,
                    maxWidth: 300
                });

          google.maps.event.addListener(marker, "click", function() {
                    if (currentPopup != null) {
                        currentPopup.close();
                        currentPopup = null;
                    }
                    popup.open(map, marker);
                    currentPopup = popup;
                });
                google.maps.event.addListener(popup, "closeclick", function() {
                    map.panTo(center);
                    currentPopup = null;
                });
