尝试在配置中加载多个pugins，但仅加载最后一个

问题描述

在CKeditor4上，我创建了不同的插件并将其加载到config中，但仅加载了最后一个。在以下情况下，仅加载plugin3。当我分别加载每个插件时，每个插件都能正常工作：

SELECT * FROM table WHERE column LIKE '%%' ESCAPE '!'

三个插件的代码相似：

CKEDITOR.editorConfig = function( config ) {
    // Define changes to default configuration here. 
    config.language = 'en';

    config.toolbarGroups = [
        { name: 'document',groups: [ 'mode','document','doctools' ] },{ name: 'clipboard',groups: [ 'clipboard','undo' ] },{ name: 'editing',groups: [ 'find','selection','spellchecker','editing' ] },{ name: 'forms',groups: [ 'forms' ] },'/',{ name: 'basicstyles',groups: [ 'basicstyles','cleanup' ] },{ name: 'paragraph',groups: [ 'list','indent','blocks','align','bidi','paragraph' ] },{ name: 'links',groups: [ 'links' ] },{ name: 'insert',groups: [ 'insert' ] },{ name: 'styles',groups: [ 'styles' ] },{ name: 'colors',groups: [ 'colors' ] },{ name: 'tools',groups: [ 'tools' ] },{ name: 'others',groups: [ 'others' ] },{ name: 'about',groups: [ 'about' ] }
    ];

    config.removeButtons = 'Save,Preview,Print,Templates,Form,HiddenField,Flash,Iframe';

    config.extraPlugins = 'plugin1';
    config.extraPlugins = 'plugin2';
    config.extraPlugins = 'plugin3';
};

为什么会这样？如何加载所有额外的插件？

解决方法

请先阅读文档：https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#cfg-extraPlugins

config.extraPlugins = 'plugin1,plugin2,plugin3';
