ckeditor5 使用第一天 下载并加载居中，居左，居右功能

 

官方网站地址https://ckeditor.com/，下载zip包或者从git上下载，

下载完成后解压文件，将文件复制到项目中

，

引用ckeditor.js，zh-cn.js路径到项目中,

初始化ckeditor,代码如下：

<textarea id="pc" name="pc" style="display: none;"></textarea>

ClassicEditor
        .create(document.querySelector('#pc'),{
            language:'zh-cn'
        })
        .catch(error => {
        console.error( error );
});
其中language代表本地化语言属性
2、自定义工具栏，添加居中，居右，居左功能，
从git上克隆项目，并确保本地安装有node.js,输入如下命令
//克隆ckeditor项目

git clone -b stable https://github.com/ckeditor/ckeditor5-build-classic.git

//进入项目路径下 

cd ckeditor5-build-classic

//npm(前提安装有node.js) 

npm install

//执行命令安装alignment插件

npm install --save-dev @ckeditor/ckeditor5-alignment
安装完成后修改ckeditor.js文件，

contentToolbar: [

'tableRow',
'mergeTableCells'
]
},
// This value must be kept in sync with the language defined in webpack.config.js.
language: 'en'
};

最后运行语句重新build

npm run build

最后生成的打包好的文件存在于build目录下，

在初始化代码中加入居左，居中，居右的属性

如下图所示：
