我无法将标记放置在已由其他符号标记的地方。 [英] I am not able to place markers on the places which is already marked by google with other symbols .
问题描述
信息窗口和标记不显示已被google标记的地点。例如：如果您运行代码并在任何地方点击，结果会出现一个标记和一个信息窗口，但这不会发生在诸如不伦瑞克，露天剧场等标记的地方。
The info window and marker is not shown for the places which is already marked by google. for example: if you run the code and click anywhere , a marker and a info window will appear as a result , but this doesn't happen for the places which are alreasy marked such as "The Brunswick","Open Air Theatre" etc.

推荐答案
当你点击这样一个地方将不会在地图上触发点击。
When you click on such a place(POI) there will no click be triggered on the map.
当您不想隐藏POI时，您必须触发您自己的点击。
When you don't want to hide the POI's, you must trigger the click on your own.
可能的方法（请参阅：当用户点击地图上的（商业）地点时，如何获得点击事件）
Possible approach(see: How to get a click event when a user clicks a (business) place on the map )
//keep a reference to the original setPosition-function
var fx = google.maps.InfoWindow.prototype.setPosition;
//override the built-in setPosition-method
google.maps.InfoWindow.prototype.setPosition = function () {
//this property isn't documented, but as it seems
//it's only defined for InfoWindows opened on POI's
if (this.logAsInternal) {
google.maps.event.addListenerOnce(this, 'map_changed',function () {
var map = this.getMap();
//the infoWindow will be opened, usually after a click on a POI
if (map) {
//trigger the click
google.maps.event.trigger(map, 'click', {latLng: this.getPosition()});
//hide the default-infoWindow of the POI
this.setMap(null);
}
});
}
//call the original setPosition-method
fx.apply(this, arguments);
};
