Maps 谷歌地图-信息窗口用计时器关闭
我对谷歌API地图有点小问题,我想知道是否有人能帮忙。我正试图让infowindows打开一些包含HREF的HTML。现在我可以使用“X”来关闭窗口,但是我更喜欢使用Javascript计时器的第二种方法来关闭信息窗口,如下所示 setTimeout('infowindow.close(map,marker)'2000') 但是,浏览器报告信息窗口在2秒过期后不存在。为了解决此问题,我尝试将infowindow对象和标记对象添加到全局范围内的数组中,但这并没有解决此问题Maps 谷歌地图-信息窗口用计时器关闭,maps,openinfowindowhtml,Maps,Openinfowindowhtml,我对谷歌API地图有点小问题,我想知道是否有人能帮忙。我正试图让infowindows打开一些包含HREF的HTML。现在我可以使用“X”来关闭窗口,但是我更喜欢使用Javascript计时器的第二种方法来关闭信息窗口,如下所示 setTimeout('infowindow.close(map,marker)'2000') 但是,浏览器报告信息窗口在2秒过期后不存在。为了解决此问题,我尝试将infowindow对象和标记对象添加到全局范围内的数组中,但这并没有解决此问题 <!DOCTYPE
