@epokk once solved problem following code: how use keypress event in angularjs?

you need add directive, this:

javascript:

app.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();             }         });     }; }); 

html:

<div ng-app="" ng-controller="mainctrl">     <input type="text" ng-enter="dosomething()">     </div>
