    copied!<p>I am having big trouble fixing this error. </p> <p>I have a view in Backbone.js and I want to bind some actions on it with keyboard events.</p> <p>Here is my view :</p> <pre><code>window.PicturesView = Backbone.View.extend({ initialize : function() { $(document).on('keydown', this.keyboard, this); }, remove : function() { $(document).off('keydown', this.keyboard, this); }, render : function(eventName) { // blah blah blah }, next : function() { // blah }, prev : function() { // blah }, keyboard : function(e) { console.log(e.keyCode); if (e.keyCode == 37) { this.prev(); return false; } if (e.keyCode == 39) { this.next(); return false; } } }); </code></pre> <p>When I press the keyboard, I get this error : <code>Uncaught TypeError: Object [object Object] has no method 'apply'</code> that is triggered by jQuery.</p> <p>After reading this : <a href="https://stackoverflow.com/questions/11032659/uncaught-typeerror-object-object-object-has-no-method-apply">Uncaught TypeError: Object [object Object] has no method &#39;apply&#39;</a></p> <p>I also tried : <code>$(document).on('keydown', function(e) { this.keyboard(e); }, this);</code> but it still gives me the same error.</p> <p>And : <code>$(document).on('keydown', 'keyboard', this);</code> in the <code>events : { 'event' : 'action' }</code> style but it doesn't do anything.</p> <p>I could probably find some hack by using jQuery only somewhere else in my code, but since I am not expert in event handling and Backbone, I want to run it the nice way.</p> <p>I hope I'm clear, thanks</p>
