javascript - Hide keystrokes from window-wide listeners -


i'm making extension chrome used on youtube. extension adds overlay on top of video text input. however, typing extension triggers youtube's various keystroke listeners (e.g. space -> pause). event.stoppropagation() nothing, neither return false @ end of angular event callback.

my current (successfully prototyped not yet implemented) solution wrap input in iframe, pass messages parent window:

iframe.contentwindow.document.queryselector("#wrapped-input").addeventlistener("input", function(){   result.innerhtml = this.value; });

i feel solution bit of hack, , i'm hoping find more elegant. aside, using angularjs app, if there angular-specific workarounds, i'd love know too. thoughts?

edit
current solution: 

<iframe id="wrapper-frame"></iframe>

...

link: {   var input = '<input id="inner-input" />';    var wrap = $window.document.queryselector('#wrapper-iframe').contentwindow.document;   $scope.commentinput = wrap.queryselector('#inner-input');    wrap.open();   wrap.write(input);   wrap.close();    $scope.commentinput.addeventlistener('input', function(){     var val = this.value;     $scope.$applyasync(function(){       $scope.inputcontent = val;     });   }); }

it works, still -- iframe. bleh, hack. leave question open in case if has better idea.
