angularjs开发常见问题-3（angularjs 解决keydown keypress 不好用现象）

app.directive('myEnter', function () {
return function (scope, element, attrs) {
element.bind("keydown keypress", function (event) {
if(event.which === 13) {
scope.$apply(function (){
scope.$eval(attrs.myEnter);
});
event.preventDefault();
}
});
};
});

<div ng-app="" ng-controller="MainCtrl">
<input type="text" my-enter="doSomething()">
</div>
