我有一个简单的脚本，可以在地图上添加标记，数据取自json。我想向所有标记添加一个基本的infoWindow，以便在单击它时显示“ Cartier”。您能告诉我InfoWindow代码在做什么错吗？代码如下。
<!DOCTYPE html>
<html>
<head>
<style>
html, body, #map-canvas {
margin: 0;
padding: 0;
height: 100%;
}
</style>
<script src="https://maps.googleapis.com/maps/api/js"></script>
<script>
var map;
function initialize() {
var mapOptions = {
zoom: 2,
center: {lat: 37.275, lng: 22.549},
mapTypeId: google.maps.MapTypeId.TERRAIN
};
map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
// Create a <script> tag and set the USGS URL as the source.
var script = document.createElement('script');
script.src = 'http://pastebin.com/raw.php?i=7X956uB3';
document.getElementsByTagName('head')[0].appendChild(script);
map.data.setStyle(function(feature) {
var jstores = feature.getProperty('jstores');
return {
icon: getCircle(jstores),
title: (jstores)
};
});
var contentString = '<div id="content">Cartier</div>';
var infowindow = new google.maps.InfoWindow({
content: contentString
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map,marker);
});
}
function getCircle(jstores) {
var circle = {
path: google.maps.SymbolPath.CIRCLE,
fillColor: 'red',
fillOpacity: .2,
scale: Math.sqrt(jstores) * 2,
strokeColor: 'white',
strokeWeight: .5
};
return circle;
}
function jewellery_stores(results) {
map.data.addGeoJson(results);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<div id="map-canvas"></div>
</body>
</html>
样本JSON：
jewellery_stores({ "type": "FeatureCollection","features": [
{"type": "Feature","geometry": {"type": "Point", "coordinates": [139.730407, 35.70883]},"properties": {"jstores": 106 }},
{"type": "Feature","geometry": {"type": "Point", "coordinates": [37.615556, 55.752222]},"properties": {"jstores": 94 }},
{"type": "Feature","geometry": {"type": "Point", "coordinates": [2.3524282, 48.8564528]},"properties": {"jstores": 89 }},
{"type": "Feature","geometry": {"type": "Point", "coordinates": [55.277067, 25.176594]},"properties": {"jstores": 66 }},
{"type": "Feature","geometry": {"type": "Point", "coordinates": [-0.1276597, 51.5072759]},"properties": {"jstores": 64 }},
{"type": "Feature","geometry": {"type": "Point", "coordinates": [114.169551, 22.285261]},"properties": {"jstores": 63 }}]
预先谢谢你，安德烈
您正在使用Google Maps Javascript API v3数据层
它支持单击侦听器，该侦听器允许您打开包含JSON中包含的属性的信息窗口。
map.data.addListener('click', function (e) {
infowindow.setPosition(e.latLng);
infowindow.setContent("hello world<br>jstores="+e.feature.getProperty("jstores")+"<br>"+e.latLng.toUrlValue(6));
infowindow.open(map);
});
工作代码段：
var map;
var infowindow = new google.maps.InfoWindow({});
function initialize() {
var mapOptions = {
zoom: 2,
center: {
lat: 37.275,
lng: 22.549
},
mapTypeId: google.maps.MapTypeId.TERRAIN
};
map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
// Create a <script> tag and set the USGS URL as the source.
var script = document.createElement('script');
script.src = 'https://pastebin.com/raw.php?i=7X956uB3';
document.getElementsByTagName('head')[0].appendChild(script);
map.data.setStyle(function(feature) {
var jstores = feature.getProperty('jstores');
return {
icon: getCircle(jstores),
title: (jstores)
};
});
}
function getCircle(jstores) {
var circle = {
path: google.maps.SymbolPath.CIRCLE,
fillColor: 'red',
fillOpacity: 0.2,
scale: Math.sqrt(jstores) * 2,
strokeColor: 'white',
strokeWeight: 0.5
};
return circle;
}
function jewellery_stores(results) {
map.data.addGeoJson(results);
map.data.addListener('click', function(e) {
infowindow.setPosition(e.latLng);
infowindow.setContent("hello world<br>jstores=" + e.feature.getProperty("jstores") + "<br>" + e.latLng.toUrlValue(6));
infowindow.open(map);
});
}
google.maps.event.addDomListener(window, 'load', initialize);html,
body,
#map-canvas {
margin: 0;
padding: 0;
height: 100%;
