And then in the add marker function, we'll provide a parameter for draggable.

然后在添加标记函数中，我们将为可拖动提供一个参数。

And then down here in the marker options, we'll set the draggable property as well.

然后在标记选项中，我们还将设置可拖动属性。

So with draggable set to false, we can't move this map around.

因此，当draggable设置为false时，我们无法移动这张地图。

One of my favorite affordances, which suggests to users that an on-screen element is draggable, is knurling – that texture added to objects to improve grip and show you where to best grab them.

我最喜欢的功能之一是滚花，它向用户暗示屏幕上的元素是可拖动的——这种纹理添加到对象上以提高抓握力并告诉您最好抓住它们的位置。
