我一直在尝试这样的事情： laststmarker is a nokia.maps.map.StandardMarker ncolor is a string= #0000FF

    laststmarker.brush=ncolor;
    laststmarker.brush="{color:'"+ncolor+"'}";
    laststmarker.brush={color:ncolor};

和其他东西，我如何在不删除的情况下更改颜色并将其再次添加到地图中？

这里要注意的重要一点是画笔是不可变的——这意味着你不能直接更新参数——你需要使用设置器，例如 marker.set("brush" , { color :"#FF0000"});——这通常是map.update(-1,0);为了刷新地图。

下面的示例在鼠标指针悬停在标记上时突出显示该标记。您需要使用自己的应用程序 ID 和令牌才能使其正常工作。
