多个谷歌地图圈的信息窗口

问题描述 投票：0回答：2

我需要为多个圈子添加信息窗口。我尝试在addListener中将cityCircle更改为citymap [city]。我现在用Google搜索了六个小时......下面的代码会弹出地图左上角的窗口，里面没有任何内容，而不是圆圈。在此先感谢您的帮助！

echo '<script>
var citymap = {'."\n";
$result = $site->query("SELECT * FROM ZIPCODES WHERE 1");
while ($data = $result->fetch_array())
{
$zip = $data['ZIP'];
$coor = explode(",", $data['COOR']);
$count = $data['COUNT'];
echo $zip . ': {
    center: {lat: ' . $coor[0] . ', lng: ' . $coor[1] . '},
    population: ' . $count . ',
    title: "<div>TEST</div>"
},'."\n";

}
echo '};

function initMap() {
var map = new google.maps.Map(document.getElementById("advisor-map"), {
    zoom: 6,
    center: {lat: 34.730318, lng: -87.823112},
    mapTypeId: "terrain"
});

for (var city in citymap) {
    var cityCircle = new google.maps.Circle({
        strokeColor: "#FF0000",
        strokeOpacity: 0.8,
        strokeWeight: 2,
        fillColor: "#FF0000",
        fillOpacity: 0.35,
        map: map,
        center: citymap[city].center,
        title: citymap[city].title,
        radius: Math.sqrt(citymap[city].population) * 10000
    });

    google.maps.event.addListener(cityCircle, "click", function (e) {
        var infoWindow = new google.maps.InfoWindow();
        infoWindow.setContent(cityCircle.title);
        infoWindow.open(map, cityCircle);
    });
}
}
google.maps.event.addDomListener(window, "load", initialize);
</script>'."\n";

  1. 创建一个infowindow：var infowindow = new google.maps.InfoWindow();
  2. 设置其内容，位置并在点击时打开它：
var infoWindow = new google.maps.InfoWindow();
google.maps.event.addListener(cityCircle, "click", function(e) {
  infoWindow.setContent(this.title);
  infoWindow.setPosition(this.getCenter());
  infoWindow.open(map);
});

代码段：

function initMap() {
  var map = new google.maps.Map(document.getElementById("advisor-map"), {
    zoom: 6,
    center: {
      lat: 55,
      lng: 0
    },
    mapTypeId: "terrain"
  });

  for (var city in citymap) {
    var cityCircle = new google.maps.Circle({
      strokeColor: "#FF0000",
      strokeOpacity: 0.8,
      strokeWeight: 2,
      fillColor: "#FF0000",
      fillOpacity: 0.35,
      map: map,
      center: citymap[city].center,
      title: city, // citymap[city].title,
      radius: Math.sqrt(citymap[city].population) * 100
    });

    var infoWindow = new google.maps.InfoWindow();
    google.maps.event.addListener(cityCircle, "click", function(e) {

      infoWindow.setContent(this.title);
      infoWindow.setPosition(this.getCenter());
      infoWindow.open(map);
    });
  }
}
google.maps.event.addDomListener(window, "load", initMap);
