I have a panel named "listState" on my aspx page

Now in that panel i have number of dropdowns.
I want id of that all dropdownlist present in "listState"

How can i do this using JQUERY

I tried following code

But it doesnt gives me id of all dropdownlist.

What to do to achieve this.

Google around for 'jQuery each', something like that might work:

    some_array[] = $(this).attr('id');
