Question

我正在添加这两个google.maps.event.addListener事件

google.maps.event.addListener(markerAcademicCenter, "mouseover", function (e) {
   markerIconAcademicCenter.url = 'MapIcons/Circle32.png'
});
google.maps.event.addListener(markerAcademicCenter, "mouseout", function (e) {
   markerIconAcademicCenter.url = 'MapIcons/Circle64.png'
});

在此标记下方已有点击事件。

google.maps.event.addListener(markerAcademicCenter, "click", function (e) {
   $(".campusMapInfoPanel > div").appendTo($(".InfoStorageDiv"));
   $(".InfoPanelAcademicCenter").appendTo($(".campusMapInfoPanel"));
   this.setZIndex(google.maps.Marker.MAX_ZINDEX + 1);
   setZoomWhenMarkerClicked();
   CampusMap.setCenter(markerAcademicCenter.getPosition());
});

markerIconAcademicCenter.url已在这些事件上方设置为Circle64。我希望页面加载更大的圆圈 - 64x64 - 当我悬停并离开标记区域时来回切换。

我有两个问题

当鼠标悬停在标记上时没有任何反应，但是当我点击时会发生这种情况。在页面加载后的初始单击时，地图缩放并居中在建筑物上，标记图像会调整大小。如果我再次点击该建筑物，则不会发生任何其他情况，但是：
如果我点击触发点击事件的菜单链接，function buildingFocus(markerName) {google.maps.event.trigger(markerName, "click");}该功能会将图标重置为鼠标输出事件。

为了进一步测试这种意外行为，我一次注释掉一个事件。为了澄清实际发生的事情，我首先将初始图像更改为clear.png。

当我取出鼠标悬停事件时，当我在页面加载后点击建筑事件或菜单链接作为我的第一次点击时，图像没有改变。在我删除鼠标悬停事件之前，在页面加载后第二次单击菜单时将图标更改为鼠标图像，但现在单击建筑物会导致此情况。

当我取出mouseout事件时，单击第一次单击建筑物会使图标更改为鼠标悬停图像，然后再次单击任一区域不再做任何事情。如果我点击菜单链接作为第一个或将来点击图片没有改变，但是一旦我点击了建筑物就会发生。

当我取消点击事件时，图像从未改变。单击事件本身就可以按预期在两个位置工作。

Answer 1

尝试使用：

google.maps.event.addListener(markerAcademicCenter, "mouseover", function (e) {
   markerIconAcademicCenter.setIcon('url to icon');
});

而不是下面的代码：

google.maps.event.addListener(markerAcademicCenter, "mouseover", function (e) {
   markerIconAcademicCenter.url = 'MapIcons/Circle32.png'
});

这将解决鼠标悬停和鼠标移除问题时图标大小更改的问题。

Answer 2

标记的图标不是MVCObject，API不会观察图标属性的变化。

您必须修改图标的url，然后致电setIcon以应用更改：

google.maps.event.addListener(markerAcademicCenter, "mouseover", function (e) {
  var icon = this.getIcon();
  icon.url =  'url/to/icon';
  this.setIcon(icon);
});

但我不建议，当您使用多个标记的图标更改url（或其他属性）时，会影响原始图标markerIconAcademicCenter（标记使用对原始对象）。您最好使用修改后的网址创建副本：

google.maps.event.addListener(markerAcademicCenter, "mouseover", function (e) {
  var icon = this.getIcon(),copy={};
     for(var k in icon){
      copy[k]=icon[k];
     }
  copy.url=  'url/to/icon';     
  this.setIcon(copy);
});
