How can I format currency by simple using JQuery in all format

// HTML

<input type='text' id='currency'/>

//JS

$('#currency').keyup(function (e) {

            $(this).val(formatCurrency(this.value.replace(/[,$]/g, '')));

        }).on('keypress', function (e) {

            if (!$.isNumeric(String.fromCharCode(e.which))) e.preventDefault();

        }).on('paste', function (e) {

            var cb = e.originalEvent.clipboardData || window.clipboardData;

            if (!$.isNumeric(cb.getData('text'))) e.preventDefault();

        });

        function formatCurrency(number) {

            var x = number.toString();

            var lastThree = x.substring(x.length - 3);

            var otherNumbers = x.substring(0, x.length - 3);

            if (otherNumbers != '')

                lastThree = ',' + lastThree;

            return otherNumbers.replace(/\B(?=(\d{2})+(?!\d))/g, ",") + lastThree;

        }

// Result 

1,11,11,111
