You can try this code.

$(function () {

    $('#txtnumber').keydown(function (e) {
       var key = e.charCode || e.keyCode || 0;
       $text = $(this); 
       if (key !== 8 && key !== 9) {
           if ($text.val().length === 3) {
               $text.val($text.val() + '-');
           }
           if ($text.val().length === 7) {
               $text.val($text.val() + '-');
           }

       }

       return (key == 8 || key == 9 || key == 46 || (key >= 48 && key <= 57) || (key >= 96 && key <= 105));
   })
});
