## Selectize API – Events In the [usage documentation](usage.md), a few callbacks are listed that allow you to listen for certain events. Callbacks aren't always ideal though; specifically when you wish to have multiple handlers. Selectize instances have a basic event emitter interface that mimics jQuery, Backbone.js, et al: ```js var handler = function() { /* ... */ }; selectize.on('event_name', handler); selectize.off('event_name'); selectize.off('event_name', handler); ``` ### List of Events
