AngularJS GetFocus directive. If the expression is truthy, then the element receives the focus.

ngGetFocus.js

app.directive('ngGetFocus', function() {
    return {
        restrict: 'A',
        link: function(scope, element, attr){
            scope.$watch(attr.ngGetFocus, function(value){
                if(value)
                    element.focus();
            });
        }
    };
});
