问题
So my goal here is to make the icon go from the "normalIcon" state to the "activeIcon" state on button click, which it currently does. It opens an infoWindow when the pin is clicked as well. I want the icon to go back to the "normalIcon" state when the infoWindow is closed. Right now, if you click on a different location it changes the icon back to the "normalIcon" but you have clicked on another icon which is now the "activeIcon"
Here is the javascript I have:
var normalIcon = 'Pin.png';
var activeIcon = 'Selected.png';
var locations = [
['<div class="header">Vigor XF in Outer Richmond</div><p id="address">4046 Balboa St, San Francisco,</p><p id="address-2">CA 94121, USA</p><div id="hours">MON - THU 05:30–20:00</div><div id="hours">FRI 05:30–18:00<div><div id="hours">SAT 07:00–14:30</div><div id="hours">SUN 10:00–13:00</div><div class="row"><div class="column" id="dialog"><img src="1.png" class="image"></div><div class="column"><img src="2.png"></div><div class="column"><img src="3.png"></div><div class="column"><img src="4.png"></div></div>', 37.78, -122.49, 5],
['<div class="header">Lower</div><img id="myImg" src="https://www.geocodezip.net/images/snow.png" alt="Snow" style="width:100%;max-width:300px">', 37.77, -122.43, 4],
];
function initMap() {
var map= new google.maps.Map(
document.getElementById('map'), {
zoom: 14,
center: { lat:37.78, lng:-122.44 }
});
var infowindow = new google.maps.InfoWindow();
var marker, i;
var markers = new Array();
for (i = 0; i < locations.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][1], locations[i][2]),
map: map,
icon:normalIcon
});
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infowindow.setContent(locations[i][0], locations[i][6]);
infowindow.open(map, marker);
for (var j = 0; j < markers.length; j++) {
markers[j].setIcon(normalIcon);
}
marker.setIcon(activeIcon);
};
})(marker, i));
markers.push(marker);
}
}
I have tried using infowindow.close like so
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infowindow.setContent(locations[i][0], locations[i][6]);
infowindow.open(map, marker);
for (var j = 0; j < markers.length; j++) {
markers[j].setIcon(normalIcon);
}
marker.setIcon(activeIcon);
infowindow.close(map, marker);
for (var j = 0; j < markers.length; j++) {
markers[j].setIcon(normalIcon);
}
marker.setIcon(normalIcon);
};
but that disables it completely. I feel like I am close but not quite there. Anyone have a quick fix?
回答1:
If you want the icon to change when the InfoWindow is closed, add a listener to the InfoWindow for the closeclick event:
closeclick
function()
Arguments: None
This event is fired when the close button was clicked.
google.maps.event.addListenerOnce(infowindow, 'closeclick', function() {
marker.setIcon(normalIcon);
})
