http://www.soexception.com/218/question2answer（q2a）怎么给wysiwyg-editor增加查看html源码的按钮？
需要修改WYSIWYG Editor插件根目录qa-wysiwyg-editor.php，找到下面的代码，并在最后添加“source”，如下所示。
$qa_content['script_lines'][]=array(
"qa_wysiwyg_editor_config={toolbar:[".
"['Bold','Italic','Underline','Strike'],".
"['Font','FontSize'],".
"['TextColor','BGColor'],".
"['Link','Unlink'],".
"'/',".
"['JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock'],".
"['NumberedList','BulletedList','-','Outdent','Indent','Blockquote'],".
"['Image','Flash','Table','HorizontalRule','Smiley','SpecialChar'],".
"['RemoveFormat', 'Maximize', '
Source']".
添加上“源码”的效果图如下：
