有人可以告诉我这段代码有什么问题吗?地图加载但用户的点击操作不会打开info_window或将地图重新定位到点击的点。
每当用户点击地图时,我都希望将地址的地址弹出为info_window。

答案 0 :(得分:1)
第一个问题:您正在将click侦听器添加到初始化函数之外的地图中,因此在初始化地图之前添加它:
<script type="text/javascript">
var geocoder;
var map;
var info_win;
var pos;
var marker;
function initialize()
{
google.maps.visualRefresh = true;
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(-34.397, 150.644);
var mapOptions = {
zoom: 8,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
google.maps.event.addListener(map, 'click', function() {
pos = map.getPosition();
map.setCenter(pos);
geocoder.geocode({'location': pos}, function(results, status)
{
marker = new google.maps.Marker
({
map: map,
position: pos
});
info_win = new google.maps.InfoWindow
({
content: results[0].formatted_address,
});
infowindow.open(map,marker);
});
});
}
</script>
之后你会发现google.maps.Map对象没有getPosition方法。它有一个getCenter方法,但你可能想使用latLng property of the click event instead。
google.maps.event.addListener(map, 'click', function(evt) {
pos = evt.latLng;
map.setCenter(pos);
修复打开info_win的代码,打开您创建的google.maps.InfoWindow:
info_win = new google.maps.InfoWindow
({
content: results[0].formatted_address,
});
info_win.open(map,marker);
