Laravel and Jquery Var Length

Question

I need to create a validation for my input to limit it 10 char, I dunno why my code doesnt work

{{ Form::label('send-txt', 'Category Code', array('class' => 'control-label')) }}
{{ Form::text('code', null, array('class' => 'form-control', 'placeholder' => 'Category Code')) }}


  $(document).ready( function() {        
        var maxLen = 10;

        $('#send-txt').keypress(function(event){
            var Length = $("#send-txt").val().length;
            var AmountLeft = maxLen - Length;
            $('#txt-length-left').html(AmountLeft);
            if(Length >= maxLen){
                if (event.which != 8) {
                    return false;
                }
            }
        });

});

I used laravel 4.2

You can validate it with HTML5 attributes too.

{{ Form::text('code', null, array('class' => 'form-control', 'placeholder' => 'Category Code', 'maxlength' => 10 )) }}

And as commented above, maybe you are not referencing the correct html element in your JQuery validation code. So change $('#send-txt') to $('#code') (Don't forget to add the ID attribute to your input)
