Answer 1

Note: $errors->count() works/activate after you submit the form request . If you need to get the count afterwards, you can do it like this

@if($errors->count())
    <script>
        alert( {{$errors->count()}} );
    </script>
@endif

If you wish to show the error count before submitting, you might have to AJAX or some frontend validation javascript libraries

Answer 2

the tag can't compile blade templating syntax. Instead of using blade

{{ $errors->count() }} 

you can try with php tags with echo and htmlspecialchars

<?php echo htmlspecialchars($errors->count()) ?>

Try:

var error_count =  <?php echo htmlspecialchars($errors->count()) ?>;
