（PS-是的，我查看了这个相关的stackoverflow和this blog并没有解决我的问题，也许我在其他地方犯了一些明显的错误？）
我正试图在我的谷歌地图上显示多个不同的信息窗口。当我的听众设置为：
google.maps.event.addListener(marker, 'click', function() {
infoWindow.setContent( this.html );
infoWindow.open( map, this );
});
然后，infowindows会为所有标记弹出完全空白。
当我的听众设置为：
google.maps.event.addListener(marker, 'click', function() {
infoWindow.open( map, this );
});
然后infowindows弹出标题，但它只是每个数组中显示所有标记的最后一个标题。
以下是我的谷歌地图javascript代码的总体情况：
function initAutocomplete() {
var map = new google.maps.Map(document.getElementById('map'), {
center: {lat: 35.6895, lng: 139.6917},
zoom: 13,
mapTypeId: 'roadmap'
});
// Create the search box and link it to the UI element.
var input = document.getElementById('pac-input');
var searchBox = new google.maps.places.SearchBox(input);
map.controls[google.maps.ControlPosition.TOP_LEFT].push(input);
/*var markers = [];*/
// Listen for the event fired when the user selects a prediction and retrieve
// more details for that place.
searchBox.addListener('places_changed', function() {
var places = searchBox.getPlaces();
if (places.length == 0) {
return;
}
// For each place, get the icon, name and location.
var bounds = new google.maps.LatLngBounds();
places.forEach(function(place) {
if (!place.geometry) {
console.log("Returned place contains no geometry");
return;
}
if (place.geometry.viewport) {
// Only geocodes have viewport.
bounds.union(place.geometry.viewport);
} else {
bounds.extend(place.geometry.location);
}
});
map.fitBounds(bounds);
});
setMarkers(map, food);
setMarkers(map, views);
}
var views = [
//Tokyo

];
function setMarkers(map, locations) {
// Add markers to the map
var shape = {
coord: [1, 1, 1, 20, 18, 20, 18 , 1],
type: 'poly'
};
for (var i = 0; i < locations.length; i++) {
var locale = locations[i];
var myLatLng = new google.maps.LatLng(locale[1], locale[2]);
var icon_to_use;
var infowindow = null;
if(locale[3] < 1 ){
icon_to_use = new google.maps.MarkerImage('img/views.png', new google.maps.Size(40, 40), new google.maps.Point(0,0), new google.maps.Point(0, 32));
}
else {
icon_to_use = new google.maps.MarkerImage('img/food.png', new google.maps.Size(40, 40), new google.maps.Point(0,0), new google.maps.Point(0, 32));
}
var marker = new google.maps.Marker({
position: myLatLng,
map: map,
icon: icon_to_use,
info: locale[0],
shape: shape,
zIndex: locale[3] //someday I will tie this zIndex to how a place is ranked//
});
infoWindow = new google.maps.InfoWindow({
content: locale[0]
});
google.maps.event.addListener(marker, 'click', function() {
infoWindow.setContent( this.html );
infoWindow.open( map, this );
});
}
}
如何在各自的信息窗口中显示独特的标题？
答案 0 :(得分：1)
您的标记没有html属性，因此不会在InfoWindow中设置任何内容：
google.maps.event.addListener(marker, 'click', function() {
infoWindow.setContent( this.html );
infoWindow.open( map, this );
});
使用info属性（这是您想要的），或将其重命名为html：
var marker = new google.maps.Marker({
position: myLatLng,
map: map,
icon: icon_to_use,
info: locale[0]
});
google.maps.event.addListener(marker, 'click', function() {
infoWindow.setContent( this.info);
infoWindow.open( map, this );
});
