下面是带有2个侧边栏的代码。第一个侧栏出现在您输入地址时，并且是根据实际里程排序的标题，地址和获取路线链接的列表。当您点击其中一个获取路线链接时，会出现另一个带有路线的边栏，并且会在第一个边栏的顶部显示，以便它不可见。一个X按钮也会出现在第二个边栏中，点击后，第二个边栏消失，只剩下第一个边栏。删除开始点和结束点以外的所有标记
我的问题是关于标记。当我点击第一个侧边栏的获取路线链接时，我想让第二个侧栏上的路线按照他们目前的做法弹出。但在地图上，我希望除去A和B代表要求方向的往返位置以外的所有标记。然后，当第二个侧边栏上单击X时，所有标记都会重新出现，从而将第一个侧边栏恢复为原样。
任何人都知道如何做到这一点。由于

也许这一个？ “如何删除所有标记” http://stackoverflow.com/questions/1544739/google-maps-api-v3-how-to-remove-all-markers?answertab=votes#tab-top – wf9a5m75
你尝试过什么是没有工作？有一些引用数组'gmarkkers'中的标记。 – geocodezip
