Remove add class on blur best way

JavaScript

I’m wondering if could be a better way for:


var $parentDiv = element.parent();
                var currentClass = $parentDiv.attr('class');
                element.on('blur',function() {
                    $parentDiv.removeClass();
                    $parentDiv.addClass(currentClass);
                    if(ctrl.$valid){
                        $parentDiv.addClass('has-success');
                     }
                     else{
                        $parentDiv.addClass('has-error'); 
                     }
                });

think of element such as

$('#myid')

if the input is valid

ctrl.$valid
