推荐答案

这是在 HTML5 中使用占位符 HTML 属性的方法.但是，它不适用于任何 Internet Explorer 版本.

This is how to do it in HTML5, using placeholder HTML attribute. However, it's not working in any Internet Explorer version.

    function horizontal_login_block($form) {
    $form['#action'] = url($_GET['q'], array('query' => drupal_get_destination()));
    $form['#id'] = 'horizontal-login-block';
    $form['#validate'] = user_login_default_validators();
    $form['#submit'][] = 'user_login_submit';
    $form['#prefix'] = '<div id="loginbar">';
    $form['#suffix'] = '</div>';
    $form['name'] = array(
     '#type' => 'textfield',
     '#prefix' => '<div class="usericon">',
     '#suffix' => '</div>',
     '#maxlength' => USERNAME_MAX_LENGTH,
/* Don't set default values. HTML5
     '#default_value' => t('Username'), */
     '#id' => 'userbar',
     '#size' => 15,
     '#required' => TRUE,
     '#attributes' =>array('placeholder' => t('Username'))
    );
