JQuery: attach the same callback to one or more elements

Question

I have to prevent user to insert letters in numeric fields. I use this:

 $('input[name=myinput]').live('keyup', function() {
                var $th = $(this);
                $th.val($th.val().replace(/[^0-9,\.]/g, ''));
        });

How could I list the other input fields? (I can't use $('input'))

I tried with

$('input[name=myinput],input[name=myinput2]').live('keyup', function() {
                var $th = $(this);
                $th.val($th.val().replace(/[^0-9,\.]/g, ''));
        });

but only input[name=myinput] is accepted.

Answer 1

You should use a class on the input element and then do:

$('input.eKeyup').live('keyup', function() {
    var $th = $(this);
    $th.val($th.val().replace(/[^0-9,\.]/g, ''));
});

Answer 2

Group them in a css class and use $('.className') it's faster and easier.
