With the ACE Editor, how can I unbind an event?

问题

https://github.com/ajaxorg/ace/wiki/Embedding---API

editor.session.on('change', callback);

is how you bind an event to "change". But how do I unbind it?

回答1:

Use removeListener to remove a specific callback.

editor.session.removeListener('change', callback);

or a shorter version

editor.session.off('change', callback);

Use removeAllListeners to remove all callbacks.

editor.session.removeAllListeners('change');
