Code

function ahah_example_simplest(&$form_state) {
  $form['explanation'] = array(
    '#type' => 'markup',
    '#value' => '<div>' . t('This is the very simplest AHAH example, which just replaces the HTML for a div on the page. Notice the more advanced examples in the other tabs.') . '</div>',
  );
  $initial_markup = '<div style="width: 150px; height: 150px; border: 1px solid black">' . t('This box will be replaced') . '</div>';
  $form['box'] = array(
    '#type' => 'markup',
    '#prefix' => '<div id="box">',
    '#suffix' => '</div>',
    '#value' => $initial_markup,
  );
