What is the most best way to do this via jquery?

I have a dropbox [Center Title]that has a location name/title. I need to associate the address to the name and then upon change of the dropbox, I need the address to populate in two textarea boxes

There are a bunch of centers and their corresponding addresses, so I think I want to put this in an external js file.

Here is my html, I just can't get the jquery clear in my head.

```
<fieldset name="Group1">
                <legend>Group box</legend>
                Center Title:<select name="ctrTitles" id="ctrTitles">
                <option value="Corp 1">Corp 1</option>
                <option value="Shamrock Gold">Shamrock Gold</option>
                <option value="Hensin Way">Hensin Way</option>
            </select><br /><br />
            Address 1: <textarea name="TextArea1" id="TextArea1" cols="20" rows="2"></textarea><br /><br />
            Address 2: <textarea name="TextArea2" id="TextArea2"cols="20" rows="2"></textarea>
            </fieldset>

```
