问题
I am attempting to add infowindows to the markers with PlaceDetails that are returned after a google searchbox search. When I click on the markers no infowindows open. I cannot figure out where I went wrong?
var infowindow = new google.maps.InfoWindow();
//Function for search box
var input = document.getElementById('target');
var searchBox = new google.maps.places.SearchBox(input);
var markers = [];
google.maps.event.addListener(searchBox, 'places_changed', function() {
var places = searchBox.getPlaces();
for (var i = 0, marker; marker = markers[i]; i++) {
marker.setMap(null);
}
markers = [];
var bounds = new google.maps.LatLngBounds();
for (var i = 0, place; place = places[i]; i++) {
var image = new google.maps.MarkerImage(
'img/pin_blue.png',
new google.maps.Size(15,29),
new google.maps.Point(0,0),
new google.maps.Point(8,29)
);
var shadow = new google.maps.MarkerImage(
'img/pin_shadow.png',
new google.maps.Size(33,29),
new google.maps.Point(0,0),
new google.maps.Point(8,29)
);
var shape = {
coord: [11,1,12,2,13,3,14,4,14,5,14,6,14,7,14,8,14,9,14,10,14,11,14,12,13,13,12,14,11,15,8,16,8,17,8,18,8,19,8,20,8,21,8,22,8,23,8,24,11,25,11,26,11,27,3,27,3,26,3,25,6,24,6,23,6,22,6,21,6,20,6,19,6,18,6,17,6,16,3,15,2,14,1,13,0,12,0,11,0,10,0,9,0,8,0,7,0,6,0,5,0,4,1,3,2,2,3,1,11,1],
type: 'poly'
};
var marker = new google.maps.Marker({
map: map,
icon: image,
shadow: shadow,
shape: shape,
title: place.name,
position: place.geometry.location
});
markers.push(marker);
bounds.extend(place.geometry.location);
}
map.fitBounds(bounds);
//add an infowindow
google.maps.event.addListener(markers, 'click', function() {
infowindow.setContent(place.name);
infowindow.open(map, markers[i]);
});
});
google.maps.event.addListener(map, 'bounds_changed', function() {
//var bounds = map.getBounds();
searchBox.bindTo('bounds', map);
});
};
回答1:
To get the Place Details to use in the InfoWindow, you need to make a second request to the Places API (when the marker is clicked). Inside the createMarker function (which has function closure on the "place"):
var request = {
reference: place.reference
};
google.maps.event.addListener(marker,'click',function(){
service.getDetails(request, function(place, status) {
if (status == google.maps.places.PlacesServiceStatus.OK) {
var contentStr = '<h5>'+place.name+'</h5><p>'+place.formatted_address;
if (!!place.formatted_phone_number) contentStr += '<br>'+place.formatted_phone_number;
if (!!place.website) contentStr += '<br><a target="_blank" href="'+place.website+'">'+place.website+'</a>';
contentStr += '<br>'+place.types+'</p>';
infowindow.setContent(contentStr);
infowindow.open(map,marker);
} else {
var contentStr = "<h5>No Result, status="+status+"</h5>";
infowindow.setContent(contentStr);
infowindow.open(map,marker);
}
});
});

I little bit changed your code. Try this one.
<html>

zoom : 7,
mapTypeId : google.maps.MapTypeId.ROADMAP
});
infowindow = new google.maps.InfoWindow();
//Function for search box
var input = document.getElementById('target');
searchBox = new google.maps.places.SearchBox(input);
google.maps.event.addListener(searchBox, 'places_changed', function() {
