角度按键干扰形式输入

Question

当输入字段具有焦点时，我不希望触发该函数（请参阅jsfiddle）

myApp.directive('keypressEvents', ["$document", "$rootScope", function ($document, $rootScope) {
function link($scope, $element, $attrs) {
    //console.log($document, $element, $scope, $attrs);
    $document.bind('keypress', function (e) {
        //console.log(e.key);
        var key = String.fromCharCode(e.which);
        if (key == 1 || key == 2 || key == 3) {
            //alert(key);
            $rootScope.$broadcast('keypress', e, e.which);
        }
    });
}

return {
    link: link
};
}]);

如果文本输入字段有焦点，有没有办法设置If（）条件？

在需要数字的表单字段

上使用这些

ng-blur="blurred()" ng-focus="focused()"
