I am pretty new to AngularJS but found it quite to my liking so far. For my current project I need hotkey functionality and was happy to see that it is supported since the 1.1.2 release.
The ng-keydown directive (http://code.angularjs.org/1.1.3/docs/api/ng.directive:ngKeydown) works as expected for input types but fails me for any other context like div etc. which seems odd given that the documentation says otherwise.
Here is an minimal example (http://jsfiddle.net/TdXWW/12/) of the working respectively the not working:
<input ng-keydown="keypress($event)"> <div ng-keydown="keypress($event)">
NOTE: I know this could be handled with plain jQuery (http://www.mkyong.com/jquery/how-to-check-if-an-enter-key-is-pressed-with-jquery/) but I much prefer to understand how to deal with it in AngularJS.
The ng-keydown directive tells AngularJS what to do when the keyboard is used on the specific HTML element. The ng-keydown directive from AngularJS will not override the element's original onkeydown event, both will be executed.
The ngRef attribute tells AngularJS to assign the controller of a component (or a directive) to the given property in the current scope. It is also possible to add the jqlite-wrapped DOM element to the scope. The ngRepeat directive instantiates a template once per item from a collection.
The ng-change event is triggered at every change in the value. It will not wait until all changes are made, or when the input field loses focus. The ng-change event is only triggered if there is a actual change in the input value, and not if the change was made from a JavaScript.
The ng-app directive defines the root element of an AngularJS application and starts an AngularJS Application. The ng-app directive will auto-bootstrap (automatically initialize) the application when a web page is loaded. It is also used to load various AngularJS modules in AngularJS Application.
I was having the same problem and was able to fix it by following this simple tip provided in this comment: https://stackoverflow.com/a/1718035/80264
You need to give the div a tabindex so it can receive focus.
<div id="testdiv" tabindex="0"></div>
Thanks! To wrap this up I got this working by, injecting $document into my directive, then:
MyApp.directive('myDirective', function($document) { return { ... $document.keydown(function(e){ console.log(e) }) }
