Angular.js

keydown

Angular has a mechanism to simulate 'input' event if it sniffs 'input' event is not supported by the browser. Angular will rely on a browser feature that the keypress takes effect after 'keydown' event, i.e. the input box's value will not be updated before the 'keydown' event, so in the 'keydown' event handler, js code would get an old value. This workaround is not supported by cloudbrowser, because we cannot make sure the deferred function to be invoked right after we set a new value to the input box. For similar reasons, code like this would not work. We modified our code to support 'input' event, so angular would not use this walk around in cloudbrowser now.

'''javascript var deferListener = function(ev, input, origValue) { if (!timeout) { timeout = $browser.defer(function() { timeout = null; if (!input || input.value !== origValue) { listener(ev); } }); } };

element.on('keydown', function(event) {
  var key = event.keyCode;

  // ignore
  //    command            modifiers                   arrows
  if (key === 91 || (15 < key && key < 19) || (37 <= key && key <= 40)) return;

  deferListener(event, this, this.value);
});
