Question

My client needs to scan a barcode which contains an invoice number (5 digits) and an ‘enter’ keystroke.

I need the input box to ignore the ‘enter’ key and move focus to the next input box after 5 characters.

If you could include some sample code, I would appreciate it. Thanks!

Answer 1

$('input[type=text]').on('keyup', function(e) {
    if (e.which != 27 || e.which != 8) { // check for backspace and delete
        if (e.which != 13) { // ignoring enter
            if (!this.value.replace(/\s/g, '').match(/\d/g)) { // checking for digit
                alert('Insert Digit');
                $(this).val(''); // make the field empty
            } else {
                if (this.value.length > 4) {
                    $(this).next().focus(); // automatically change current input of length 5 digits
                }
            }
        }

    }
});
