Javascript 在谷歌地图上刷新和删除标记
我是谷歌地图功能的新手,我想知道如何删除地图上的标记,刷新地图会不会删除标记,或者我是否需要添加一些东西来删除标记 我使用数据库中的Getjson循环添加标记 这是我的代码集Javascript 在谷歌地图上刷新和删除标记,javascript,jquery,google-maps,google-maps-api-3,Javascript,Jquery,Google Maps,Google Maps Api 3,我是谷歌地图功能的新手,我想知道如何删除地图上的标记,刷新地图会不会删除标记,或者我是否需要添加一些东西来删除标记 我使用数据库中的Getjson循环添加标记 这是我的代码集 var Rad = 0; var customerlocationID = 0; var geocoder, infoBubble, geocode; var map; var selectedMarker; var ID; //var mgr; $("#ddlRadius").live("change", functi
