Question

I found this cod on jquery web

$("select").change(function () {
      var str = "";
      $("select option:selected").each(function () {
            str += $(this).text() + " ";
          });
      $("div").text(str);
    })
    .change();

I can use it for I want but I want this function to be fired only for #my_id. I tried to insert #my_id after both selects but then the function does nothing.

I though I could bind this function to only select with specific id.

Answer 1

That works fine for select#my_id:

Did you use select #my_id (note the space) my mistake?

The select#my_id selector matches the <select id="my_id"> element, the select #my_id matches anything with and id="my_id" that is a child of a <select>.
