问题
I want to know how to trigger an event when I click on an infoWindow using Google Maps API v3. In this example, when I click on a marker, an info window shows up with a unique message, based on which marker I clicked. I want to also be able to click the info window and have an alert show up that says
"You clicked on the infowindow for (__fill in blank location_)
I found some examples using Google Maps API v2 and jQuery, but not with just plain old Google Maps API v3.

Update I ended up figuring this out for InfoBox as well, which is included below in my answer.

Ok I figured this out for infoWindow, but then I also figured it out for InfoBox since it is prettier and more customizable. I'm new to JavaScript and these closures can be very tricky.
For infoWindow

回答2:
The InfoWindow object does not have a 'click' event, so you cannot do
google.maps.event.addListener(infowindow, 'click',....
instead, you can attach an event handler to the DOM object, such as
function addMarker(latLng, name){
var marker = new google.maps.Marker({
map:map,
position:latLng
});
G.event.addListener(marker,'click',function(mev){
var div = document.createElement('div');
div.innerHTML = name;
div.onclick = function(){iwClick(name)};
infoWindow.setContent(div);
infoWindow.setPosition(mev.latLng);
infoWindow.open(map);
});
}
function iwClick(str){
alert(str);
};
and you call it with
var chicago = new google.maps.LatLng(41.850033, -87.6500523);
addMarker(chicago,'chicago');

Thanx! Erin is tha man! You fixed my problem! I was bashing it for 4 days now! Closures are a pain in the * if you are new to them.
Here's is my working code (Sencha Touch 2 and Google maps API v3). It will oly allow one infowindow to be open.
var openedInfoWindow = null;
var boxList = [];
var marker, i;
//build info box object
var infoWindow = new google.maps.InfoWindow({
enableEventPropagation: true,
});
//handle close
google.maps.event.addListener(infoWindow, 'closeclick', function() {
openedInfoWindow = null;
});
//loop trough store data...
for(i in data) {
//data
var itemData = data[i].getData();
//marker
var geopos = new google.maps.LatLng(itemData['lat'], itemData['lng']);
var marker = new google.maps.Marker({
position: geopos,
//icon: image,
map: map,
title: itemData['title'],
id: i,
animation: google.maps.Animation.DROP
});
//add info window content to DOM
var boxText = document.createElement("div");
boxText.id = i;
boxText.className = "labelText" + i;
boxText.data = itemData;
boxText.innerHTML = '<b>' + itemData['title'] + '</b>' + (itemData['distance'] ? ' (' + itemData['distance'] + ')' : '') + '<br />' + (itemData['address'] != itemData['title'] ? itemData['address'] : '') + (itemData['price'] ? '<br />' + itemData['price'] : '') + '<br /><a class="button">Meer info</a>';
boxList.push(boxText);
//add marker click event
google.maps.event.addListener(marker, 'click', (function(marker, i) {
if (openedInfoWindow != null)
openedInfoWindow.close();
return function() {
infoWindow.setContent(boxList[this.id]);
infoWindow.open(map, marker);
openedInfoWindow = infoWindow;
}
})(marker, i));
//when infowindow is clicked, open view...
google.maps.event.addDomListener(boxList[i],'click',(function(marker, i) {
return function(){
iStuddy.app.pushView('kames_detail',boxList[i].data);
}
})(marker, i));
}

my solution: try use onClick in xml
<InfoWindow onCloseClick={props.onToggleOpen}>
<div onClick={()=>{alert('hello')}} class="wow slideInLeft">
<img src="https://i.imgur.com/7IgBxnH.jpg" width="150px" />
<div>nhà trọ cho thuê</div>
<div>1.500.000đ</div>
</div>
</InfoWindow>
