    $JFriendsSwitch->setAttribute('class', 'joe_content joe_other');
    $form->addInput($JFriendsSwitch->multiMode());

    $JFriends = new Typecho_Widget_Helper_Form_Element_Textarea(
        'JFriends',
        NULL,

         格式：博客名称 || 博客地址 || 博客头像 || 博客简介 || 友链页面地址 <br />
         其他：一行一个，一行代表一个友联'

    $JFriends->setAttribute('class', 'joe_content joe_other');
    $form->addInput($JFriends);
