我查看了api文档,但找不到很多。我被困在尝试使用下面的代码创建一个可点击的图标,该代码显示一个弹出信息框:
function initialize() {
var myLatLng = new google.maps.LatLng(52.288, 0.78);
var myOptions = {
zoom: 8,
center: myLatLng,
mapTypeId: google.maps.MapTypeId.HYBRID
};
var map = new google.maps.Map(document.getElementById("map_canvas"),
myOptions);
<?php
$sql_launch = mysql_query("SELECT * FROM pred_route WHERE time = (SELECT MIN(time) FROM pred_route)");
$sql_land = mysql_query("SELECT * FROM pred_route WHERE time = (SELECT MAX(time) FROM pred_route)");
$sql_pop = mysql_query("SELECT * FROM pred_route WHERE alt = (SELECT MAX(alt) FROM pred_route)");
?>
var contentString = '<div id="content">'+
'<div id="siteNotice">'+
'</div>'+
'<h1 id="firstHeading" class="firstHeading">Uluru</h1>'+
'<div id="bodyContent">'+
'<p><b>Uluru</b>, also referred to as <b>Ayers Rock</b>, is a large ' +
'sandstone rock formation in the southern part of the '+
'Northern Territory, central Australia. It lies 335 km (208 mi) '+
'south west of the nearest large town, Alice Springs; 450 km '+
'(280 mi) by road. Kata Tjuta and Uluru are the two major '+
'features of the Uluru - Kata Tjuta National Park. Uluru is '+
'sacred to the Pitjantjatjara and Yankunytjatjara, the '+

var infowindow = new google.maps.InfoWindow({
content: contentString
});
var image_balloon = new google.maps.MarkerImage("http://projectstratos.com/images/map/balloon.png",new google.maps.Size(32,37));
var balloon_longlat = new google.maps.LatLng(<?php echo $current['lat'] . ", " . $current['long']; ?>);
var balloon = new google.maps.Marker({
position: balloon_longlat,
map: map,
icon: image_balloon
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map,image_balloon);
});
最佳答案
您在addListener中引用了错误的对象-使用marker
,而您应该使用balloon
。 Marker对象未添加到地图。
更改此:
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map,image_balloon);
});
至
google.maps.event.addListener(balloon, 'click', function() {
infowindow.open(map,image_balloon);
});
