<input type="text" id='number' name="mobile"/>

<script>
    $("#number").keydown(function(event)

    {

        if ( $.inArray(event.keyCode,[46,8]) !== -1 || (event.keyCode == 65 && event.ctrlKey === true) || (event.keyCode >= 35 && event.keyCode <= 39))

        {

            return;

        }

        else
        {

            if (event.shiftKey || (event.keyCode < 48 || event.keyCode > 57) && (event.keyCode < 96 || event.keyCode > 105 ))

            {

                event.preventDefault();

            }

        }

    });
</script>
