phpcms/libs/classes/form.class.php找['Maximize']，在它下面添加['autoformat']

statics/js/ckeditor/config.js找到config.extraPlugins修改为

config.extraPlugins = 'capture,autoformat';

statics\js\ckeditor\plugins 新建文件夹autoformat并新建文件plugin.js

(function() {CKEDITOR.plugins.add('autoformat', {requires: ['styles', 'button'],init: function(a) {a.addCommand('autoformat', CKEDITOR.plugins.autoformat.commands.autoformat);a.ui.addButton('autoformat', {label: "清除格式，一键排版",command: 'autoformat',//这个autoformat.gif是你的插件图标，放在同目录下 icon: this.path + "autoformat.gif"});}});CKEDITOR.plugins.autoformat = {commands: {autoformat: {exec: function(a) {var _html = a.getData();//清除样式代码 _html = _html.replace(/<div/ig, '<p');_html = _html.replace(/<\/div>/ig, '</p>');_html = _html.replace(/<strong[^>]*>/ig, '');_html = _html.replace(/<\/strong>/ig, '');_html = _html.replace(/<em[^>]*>/ig, '');_html = _html.replace(/<\/em>/ig, '');_html = _html.replace(/<u[^>]*>/ig, '');_html = _html.replace(/<\/u>/, '');_html = _html.replace(/<li[^>]*>/ig, '');_html = _html.replace(/<\/li>/ig, '');_html = _html.replace(/<span[^>]*>/ig, '');_html = _html.replace(/<\/span>/ig, '');_html = _html.replace(/&nbsp;/ig, '');_html = _html.replace(/　/ig, '');_html = _html.replace(/<p><\/p>/ig, '');_html = _html.replace(/<a/ig, '<a rel="nofollow"');//将p标签替换成<br /> _html = _html.replace(/<p[^>]*>/ig, '');_html = _html.replace(/<\/p>/ig, '<br />');_html = _html.replace(/<br \/><br \/>/ig, '<br />');_html = _html.replace(/[\n]/ig, '');//按<br />分组，将换行<br>全部替换成p标签 bb = _html.split("<br />");aa = '';for (var i = 0; i < bb.length; i++) {aa = aa + '<p>' + bb[i] + '</p>';}//首行缩进 _html = aa.replace(/<p[^>]*>/ig, '<p>　　');_html = _html.replace(/<p>　　<\/p>/ig, '');_html = _html.replace(/<p><\/p>/ig, '');//在这里执行你将_html中的空行替换掉的操作 a.setData(_html);}}}};
})();
