CKEditor扩展插件:自动排版功能

 

CKEditor是新一代的FCKeditor,是一个重新开发的版本。CKEditor是全球最优秀的网页在线文字编辑器之一,因其惊人的性能与可扩展性而广泛的被运用于各大网站。

如果还没接触过的可以看看,在线演示地址:http://ckeditor.com/demo

当然了,今天我们的主要目的还不是介绍。

还未下载CKEditor的同学可以点击下载:http://ckeditor.com/download

下载完后的结构是这样的:

好了,开始制作了,我们照着执行顺序来吧。

1.注册插件

首先找到根目录下的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";
 

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:

1 (function()
2 {
3     CKEDITOR.plugins.add('autoformat',{
4         init:function(editor){
5         //初始化操作
6         }
7     });
8 })();

添加一个命令和按钮在初始化函数中,如下:

 

1 (function()
2 {
3     CKEDITOR.plugins.add('autoformat',{
4         init:function(editor){
5             editor.addCommand( 'autoformat', new CKEDITOR.autoformatCommand());
6             editor.ui.addButton('Autoformat',{label:'自动排版',command:'autoformat',icon:CKEDITOR.getUrl( this.path + 'images/autoformat.gif' )});
7         }
8     });
9 })();

 

 

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

好了,直接放出所有代码吧

  1 //一键排版
  2 (function () {
  3     CKEDITOR.plugins.add('autoformat', {
  4         requires: ['styles', 'button'],
  5         init: function (a) {
  6             a.addCommand('autoformat', CKEDITOR.plugins.autoformat.commands.autoformat);
  7             a.ui.addButton('autoformat', {
  8                 label: "一键排版",
  9                 command: 'autoformat',
 10                 icon: this.path + "images/autoformat.gif"
 11             });
 12         }
 13     });
 14     CKEDITOR.plugins.autoformat = {
 15         commands: {
 16             autoformat: {
 17                 exec: function (editor) {
 18                     formatText(editor);
