首先找到根目录下的ckeditor/config.js文件，打开文件如下：
CKEDITOR.editorConfig = function (config) { // Define changes to default configuration here. For example: // config.language = 'fr'; // config.uiColor = '#AADC6E'; };
我们需要将我们的插件注册进CKEDITOR中。
在方法内部加入如下代码：
config.extraPlugins = "autoformart";
如果值中有其他字符,则用","逗号分隔,增加.
2.创建Plugin.js文件
在Plugins文件下新建一个与插件名相同的文件夹：aotuformart 的文件夹，意为自动排版。
再在文件夹内创建一个plugin.js文件，因为在注册插件后，首先加载和执行的就是plugin.js这个文件。
首先我们构建一个自执行函数，在自执行函数中添加一个插件：
(function() { CKEDITOR.plugins.add('autoformat',{ init:function(editor){ //初始化操作 } }); })();
添加一个命令和按钮在初始化函数中，如下：
(function() { CKEDITOR.plugins.add('autoformat',{ init:function(editor){ editor.addCommand( 'autoformat', new CKEDITOR.autoformatCommand()); editor.ui.addButton('Autoformat',{label:'自动排版',command:'autoformat',icon:CKEDITOR.getUrl( this.path + 'images/autoformat.png' )}); } }); })();
addCommand方法有两个参数：插件命令名称，第二个是命令执行的方法。
addButton方法的第一个参数是：插件的按钮名称
label：鼠标悬浮时插件提示
command：执行插件命令的名称
icon：插件图标
所有代码(上边的两块代码为演示注册插件)
//一键排版 (function () { CKEDITOR.plugins.add('autoformat', { requires: ['styles', 'button'], init: function (a) { a.addCommand('autoformat', CKEDITOR.plugins.autoformat.commands.autoformat); a.ui.addButton('autoformat', { label: "一键排版", command: 'autoformat', icon: this.path + "images/autoformat.png" }); } }); CKEDITOR.plugins.autoformat = { commands: { autoformat: { exec: function (editor) { formatText(editor); } } } }; //格式化 function formatText(editor) { var myeditor = editor; if (myeditor.mode == "wysiwyg") { var tempimg = new Array(); var temptable = new Array(); var tempobject = new Array(); var isPart = false; //暂时无法实现局部格式化 if (!isPart) { var tmpDiv = document.createElement("DIV"); var editorhtml = myeditor.getData(); editorhtml = editorhtml.replace(/<div>\s*<span> <\/span>\s*<\/div>/gi, '<p>[ page]</p>'); //将div span标签替换为p 标签 tmpDiv.innerHTML = editorhtml.replace(/ /gi, '').replace(/<div/gi, '<p').replace(/<\/div/gi, '</p'); //移除空格标签，div替换为p标签。 if (window.navigator.userAgent.toLowerCase().indexOf("msie") > 0) { tmpDiv.innerHTML = tmpDiv.innerHTML.replace(/<\/p>/gi, '<br /><\/p>'); //每个段落相隔一行 } var tables = tmpDiv.getElementsByTagName("TABLE"); if (tables != null && tables.length > 0) { for (var j = 0; j < tables.length; j++) { temptable[temptable.length] = tables[j].outerHTML; } var formattableCount = 0; for (var j = 0; j < tables.length;) { tables[j].outerHTML = "#FormatTableID_" + formattableCount + "#"; formattableCount++; } } var objects = tmpDiv.getElementsByTagName("OBJECT"); if (objects != null && objects.length > 0) { for (var j = 0; j < objects.length; j++) { tempobject[tempobject.length] = objects[j].outerHTML; } var formatobjectCount = 0; for (var j = 0; j < objects.length;) { objects[j].outerHTML = "#FormatObjectID_" + formatobjectCount + "#";

formatImgCount++; } } var strongarray = new Array(); var strongcount = 0; for (var i = 0; i < tmpDiv.getElementsByTagName('b').length; i++) { strongarray[strongcount] = tmpDiv.getElementsByTagName('b')[i].innerText.trim(); tmpDiv.getElementsByTagName('b')[i].innerHTML = "#FormatStrongID_" + strongcount + "#"; strongcount++; } for (var i = 0; i < tmpDiv.getElementsByTagName('strong').length; i++) { strongarray[strongcount] = tmpDiv.getElementsByTagName('strong')[i].innerText.trim();

//p标签替换回原来的div和span标签。 if (temptable != null && temptable.length > 0) { for (var j = 0; j < temptable.length; j++) { var tablehtml = temptable[j]; html = html.replace("#FormatTableID_" + j + "#", tablehtml);

3、配置到菜单中
例basic模式：
['Bold', 'Italic', '-', 'NumberedList', 'BulletedList', '-', 'Link', 'Unlink' ],['Maximize']
改为
['Bold', 'Italic', '-', 'NumberedList', 'BulletedList', '-', 'Link', 'Unlink' ],['Maximize','autoformat']
4、图标
当前占位已经实现，但由于没有图标，显示上会有问题，此时自己找或制作一个图标，放到autoformat/images/下命名为autoformat.png
借用某编辑器的：
