问题描述
我在使用Google地图脚本时遇到麻烦,在同一位置上的标记重叠并且用户看不见. 我尝试使用此链接中的OverlappingMarkerSpiderfier编辑脚本 https://github.com/jawj/OverlappingMarkerSpiderfier .但是存在重叠的问题.没有改善.
I have trouble with my google map script where the markers on a same location overlapped and not visible to user. I tried to edit my script using OverlappingMarkerSpiderfier available in this link https://github.com/jawj/OverlappingMarkerSpiderfier. But overlapping issue exist.No improvement occured.
<script type="text/javascript">
