Question

在我的网站上，我整合了谷歌地图api并设置了一个标记，但现在想要实现将标记拖动到更具体/更准确位置的功能。

我已复制下面的代码供大家查看，正确映射功能，但无法拖动光标。

尝试将其添加到jsfiddle，但不确定如何使用它http://jsfiddle.net/TJ94t/

帮助永远赞赏。

Answer 1

在创建marker_options时添加 draggable 属性并将其值设置为true。

var marker_options = {position: point, map: map, title: title, draggable: true};

有关marker_options（以及可订阅的拖动事件）的更多信息，请参阅Google's Map Api documentation.

如何将谷歌地图api中创建的标记拖动到特定位置？
