<input ng-keyup="event=$event">
//<p>event keyCode: {{ event.keyCode }}</p>
//<p>event altKey: {{ event.shiftKey }}</p>

myApp.directive(\'ngEnter\', function () {

   return function (scope, element, attrs) {

     element.bind("keydown keypress", function (event) {

       if (event.which === 13) {

         scope.$apply(function () {

           scope.$eval(attrs.ngEnter);

         });

         event.preventDefault();

       }

     });

   };

 });

 

在对应的控制器中的$scope上绑定一个shirtKeyCheck方法

$scope.shirtKeyCheck=function($event){

  if($event.keyCode==13){//回车13，shift键为16 

    alert(\'按下了回车键\');

  }

}
