篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了多个谷歌地图圈的信息窗口相关的知识，希望对你有一定的参考价值。
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 = {'."
";
$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>"
},'."
";
}
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>'."
";
答案
- 创建一个infowindow：
var infowindow = new google.maps.InfoWindow(); - 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);

这就是我想要的。地图还有汽车中心和变焦。希望这有助于某人！
