How to add forward slash automatically in keyup function

Question

I'm having some field in which when the user types after 2nd alphabet, I need to add forward slash automatically. Is this possible in jquery?

<input type="text" class="someclass"/>

    $(document).on('keyup','.classname', function(){
      var count = $(this).val();
    if(count == 2)
    {
      // Need stuff here
    }

});

Answer 1

You can use:

$(document).on('keyup','.someclass', function(){
    var count = $(this).val().length;
    if(count == 2 && e.keyCode != 8){
      $(this).focus().val(function( index, value ) { return value + "/ " ;   });
    }
});

Answer 2

You could do this:

 $(document).on('keyup', '.someclass', function(e) { var count = $(this).val().length; if (count == 2) { $(this).val($(this).val() + "/"); } });
