            if (numWords > maxWords && maxWords != 0) {
                $(this).siblings('.word-count-wrapper').addClass('error');

                var trimmedString = '';
                var wordArray = $(this).val().split(/[\s\.\?]+/);
                for (var i = 0; i < maxWords; i++) {
                    trimmedString += wordArray[i] + ' ';
                }

                $(this).val(trimmedString);
            }
            else if (numWords == maxWords && maxWords != 0) {
                $(this).siblings('.word-count-wrapper').addClass('error');
            }
            else {
                $(this).siblings('.word-count-wrapper').removeClass('error');
            }

        }).after('<span class="word-count-wrapper">Total Word Count: <span class="word-count">0</span></span>');
    });
});

Is there any way when the field reached the number of words, it won't delete them, just stop? even after copy-paste higher number of words?
