谷歌地图API JavaScript-点击更改标记图标

Question

如果这已经发布了，我很抱歉，但我花了至少一个小时试图找到合适的最新解决方案。

我可以设置自定义标记图像，但无法为正常和单击状态设置不同的标记图像。我找到了。这是我正在使用的代码

var map = new google.maps.Map(document.getElementById('map'), {
zoom: 14,
center: center
});
var infowindow = new google.maps.InfoWindow({});
var marker, count;
for (count = 0; count < locations.length; count++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[count][1], locations[count][2]),
map: map,
title: locations[count][0],
icon: image
});
marker.addListener("click", () => {
marker.setIcon("/wp-content/uploads/2020/07/Selected.svg");
});
google.maps.event.addListener(marker, 'click', (function(marker, count) {
return function() {
infowindow.setContent(locations[count][0]);
infowindow.open(map, marker);
}
})(marker, count));
}
}

此部分会在单击时更改标记图标，但仅针对第一个，并且在单击其他标记时不会更改为未选择的图标。

marker.addListener("click", () => {
marker.setIcon("/wp-content/uploads/2020/07/Selected.svg");
});

Answer 1

尝试将setIcon放入google.maps.event.addListener中

例如

google.maps.event.addListener(marker, 'click', function() {
return function() {
marker.setIcon("/wp-content/uploads/2020/07/Selected.svg");
}
});

Answer 2

最终我弄明白了。这是工作代码。我得到了列出位置的PHP部分，但这足以回答这个问题。

var markers = [];
var normalIcon = '/wp-content/uploads/2020/07/Pin.svg';
var activeIcon = '/wp-content/uploads/2020/07/Selected.svg';
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 14,
center: center
});
var infowindow = new google.maps.InfoWindow({});
var marker, count;
for (count = 0; count < locations.length; count++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[count][1], locations[count][2]),
map: map,
title: locations[count][0],
icon: normalIcon
});
markers.push(marker);
google.maps.event.addListener(marker, 'click', (function(marker, count) {
return function() {
for (var j = 0; j < markers.length; j++) {
markers[j].setIcon(normalIcon);
}
this.setIcon(activeIcon);
infowindow.setContent(locations[count][0]);
infowindow.open(map, marker);
}
})(marker, count));
}
