There are several options.

1. Select all select elements on the page:

   $("select").change(function(){xxx});
   

2. Select only those select elements contained within a form having the ID formD:

   $("form#formD select").change(function(){xxx});
   

3. Select only those select elements in class d (add a class HTML attribute to each select element):

   $("select.d").change(function(){xxx});
   

4. Select only those select elements whose names/IDs begin with d:

   $("select[name^=d]").change(function(){xxx});
   

5. Select only those select elements specifically named by ID (add an id HTML attribute to each select element):

   $("select#d1, select#d2").change(function(){xxx});
   

6. Select only those select elements specifically named using the name attribute (which I would try to avoid because it is less readable):

   $("select[name='d1'], select[name='d2']").change(function(){xxx});

$("select[name='d1'],select[name='d2']").change(function(){xxx});

You could select d1 or d2:

$("select[name='d1'], select[name='d2']").change(function(){xxx});

But it would be more elegant if you assigned them the same class and then selected based on that:

<select name="d1" class="d">...</select>
<select name="d2" class="d">...</select>

$("select.d").change(function(){xxx});

$("select[name^=d]") - will return all selects with name beginning in d. Here is the fiddle: http://jsfiddle.net/KjURE/ . This is exactly what you asked for
