Give focus to an input field of a form

Hi,    I am new to rails and I have setup Typo on my site. One little thing bugs me, the login page doesn't give focus to the "user_login" field. I was wondering what do I need to do to make rails help with this? I have seen some simple inline javascript to set the focus, sort of like:

document.<form_name>.user_login.focus()

However the rails view doesn't have name for the form, so that code won't work. Below is the code for the login.rhtml from Typo:

<% form_tag :action=> "login" do %>

<div title="Account login" id="loginform">

    <h3>Typo</h3>

    <div class="form admin">       <% if flash[:notice] %>         <h4><%= flash[:notice] %></h4>       <% end %>       <ul>         <li>           <label for="user_login" class="block"><%= _('Username')%>:</

          <input type="text" name="user_login" id="user_login" size="20" value=""/>         </li>         <li>           <label for="user_password" class="block"><%= _('Password') %>:</label>           <input type="password" name="user_password" id="user_password" size="30"/>         </li>       </ul>       <input type="submit" name="login" value= "<%= _('Login') %> &#187;" class="primary" />       <p><%= link_to "&laquo; " + _('Back to the blog'), { :controller => '/articles' } %></p>     </div> </div>

<% end %>

I want to give focus to the user_login field when the page loads. Any ideas?

Thanks!

any one?
