没有标记的Google Maps infoWindow?

问题描述

根据文档，标记是infoWindow的可选标记，那么如何实现?我已经尝试过 infowindow.open(map)和 infowindow.open(map，null)，但是都不会产生任何效果.

According to the documention a marker is optional with an infoWindow, so how is this achieved please? I have tried infowindow.open(map) and infowindow.open(map,null) but both produce nothing.

推荐答案

infowindow.open(map)没有意义，因为您需要指定信息窗口应打开的位置，并且它还具有一个锥形茎杆，用于指定应该指向的位置

infowindow.open(map) makes no sense since you need to specify the position where the infowindow should open, also it has a tapered stem which specifies the location where it should point.

根据Infowindows的文档 可以附加到Marker对象(在这种情况下，它们的位置取决于标记的位置)，也可以附加到指定LatLng上的地图本身.

According to the documentation of Infowindows- InfoWindows may be attached to either Marker objects (in which case their position is based on the marker's location) or on the map itself at a specified LatLng.

因此，如果您不希望标记打开信息窗口，请使用地图点击事件-

So if you donot want the marker to open the infowindow, use the map click event-

var iwindow= new google.maps.InfoWindow;
    google.maps.event.addListener(map,'click',function(event)
    {
         iwindow.setContent(event.latLng.lat()+","+event.latLng.lng());
         iwindow.open(map,this);
         iwindow.open(map,this);
    });

然后关闭InfowWindow- infowindow.setMap(null);

And to close a InfowWindow- infowindow.setMap(null);

希望可以消除您的疑虑.

Hope that cleared your doubts.
