Changing the selected index of my dropdown using Jquery

Hello all i am trying to change one dropdowns selected index once another is changed, and i want to use jquery to select the dropdowns. Here is some of my code:

<div id = "monthlist">
<select name = "months">
   <option value = 1 > January </option>
   <option value = 2 > Febuary </option>
   <option value = 3 > March </option>
   <option value = 4 > April </option>
   <option value = 5 > May </option>
   <option value = 6 > June </option>
   <option value = 7 > July </option>
   <option value = 8 > August </option>
   <option value = 9 > September </option>
   <option value = 10 > October</option>
   <option value = 11 > November </option>
   <option value = 12 > December </option>
   </select>
   </div>

   <div id = "yearlist">
   <select name = "years">
   <option value = 1993 > 1993 </option>
   <option value = 1994 > 1994 </option>
   <option value = 1995 > 1995 </option>
   <option value = 1996 > 1996 </option>
   <option value = 1997 > 1997 </option>
   <option value = 1998 > 1998 </option>
   <option value = 1999 > 1999 </option>
   <option value = 2000 > 2000 </option>
   <option value = 2001 > 2001 </option>
   </select>
   </div>

The JQuery code is here:

$("#monthlist").change(function(){

        $("select#yearlist").prop('selectedIndex', 2);
    });

I want to set the selected index of "yearlist" to a specific index once the monthlist dropdown is changed. But my selector or my code is incorrect, any suggestion or tips will be greatly appreciated.

You're trying to select the month and year lists by their names. Use the ID of the outer divs instead...

$("div#monthlist select").change(function(){
    $("div#yearlist select")[0].selectedIndex = 2;
});

is it you are looking for ??

$("#monthlist").change(function(){
    $("#yearlist").get(0).selectedIndex = 2; 
}

And correction to your case :

$("#monthlist").change(function(){
    $("select#yearlist").attr('selectedIndex', 2);
}

And one more choice for index 

$("#monthlist").change(function(){
    $('#yearlist option').eq(2).attr('selected', 'selected');
}
