Question

Here is the map I am working on。我试图一次只打开一个infowindow，当点击地图或其他标记时，打开的infowindow将会关闭。

我知道已经多次询问和回答了这个问题，但是我已经尝试过这些示例，并且无法弄清楚如何将它们应用到我的特定代码中，这些代码从Flickr和把它们放在与标记相关的信息下。我非常确定该解决方案涉及创建一个infowindow并更改其内容。

代码段（来自小提琴）：

＆＃13;

var lat = 0;
var long = 0;

$(document).ready(function() {

  $.getJSON("https://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=14fca78b18f8e8f4d22216494ea29abf&user_id=136688117%40N05&has_geo=1&extras=geo&format=json&jsoncallback=?", displayImages3);

  function displayImages3(data) {


    $.each(data.photos.photo, function(i, item) {

      lat = item.latitude;
      lng = item.longitude;

      var photoURL = 'https://farm' + item.farm + '.staticflickr.com/' + item.server + '/' + item.id + '_' + item.secret + '_m.jpg';
      var linkURL = 'https://www.flickr.com/photos/' + item.owner + '/' + item.id + '';
      htmlString = '<a href="' + linkURL + '" target="_blank"><img src="' + photoURL + '"></a>';
      var contentString = '<div id="content">' + htmlString + '</div>';

      var infowindow = new google.maps.InfoWindow({
        content: contentString
      });

      var myLatlngMarker = new google.maps.LatLng(lat, lng);

      var marker = new google.maps.Marker({
        position: myLatlngMarker,
        map: myMap
      });
      marker.setIcon('https://www.sherrihill.com/static/skin/images/pinkdot_pink-dot.png');

      google.maps.event.addListener(marker, 'click', function() {
        infowindow.open(myMap, marker);
      });
    });
  }

});

var myLatlngCenter = new google.maps.LatLng(46.140743, -116.682910);
var mapOptions = {
  center: myLatlngCenter,
  zoom: 6,
  mapTypeId: google.maps.MapTypeId.ROADMAP
};
var myMap = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);

  margin: 0;
  padding: 0

Answer 1

在全球范围内制作单一信息窗口。重复使用它以显示每个标记的内容。在此示例中，我将infowindow的HTML内容添加为标记的属性，然后使用this.htmlContent在标记单击事件侦听器中访问它。

var contentString = '<div id="content">' + htmlString + '</div>';

var myLatlngMarker = new google.maps.LatLng(lat, lng);

var marker = new google.maps.Marker({
  position: myLatlngMarker,
  map: myMap,
  icon: 'https://www.sherrihill.com/static/skin/images/pinkdot_pink-dot.png',
  htmlContent: contentString
});

google.maps.event.addListener(marker, 'click', function() {
  infowindow.setContent(this.htmlContent);
  infowindow.open(myMap, this);
});
