Created April 16, 2013 09:27
AngularJS ngFocus and ngBlur directives - one way to get them before they get released. Before using, consider re-naming ngFocus and ngBlur to something that doesn't invade the ng namespace, e.g. replace all 'ngFocus' and 'ngBlur' strings with 'ngcFocus' and 'ngcBlur' (where c = cats/custom).
app.directive('ngFocus', ['$parse', function($parse) {
return function(scope, element, attr) {
var fn = $parse(attr['ngFocus']);
element.bind('focus', function(event) {
scope.$apply(function() {
fn(scope, {$event:event});
});
});
}
}]);
