openlayers交互事件取消注册

Question

I am trying to dynamically change interaction behaviour. It seems to have hit a wall with unregistering the events anyone that can help me with this?

This code:

map.un("click",ol.interaction.DragBox.handleDownEvent_,ol.interaction.DragBox);

gets a undefined error

Answer 1

You cannot manipulate the internals of the library this way. What you can do is use setActive(false) on the interaction.
