Need help w/ toggling anchor + button

Heeey PunBB

How do i make a jQuery script that toggles visibility of a div and at the same time toggles anchor text of a button?

function toggle(user_id) {
   e = document.getElementById('toggleUserinfo_' + user_id);
   a = document.getElementById('displayUserinfo_' + user_id);
   if (e.style.display == 'block') {
       e.style.display = 'none';
       a.innerHTML = ‘Open';
   } else {
       e.style.display = 'block';
       a.innerHTML = ‘Close';
   }
}

I tried to search for it and came up with the following. However i want something more clean and based on jQuery instead of javascript. I need the script to show more information in the table with a button here
.

Any ideas or suggestions?
