SpreadJS 集成案例

介绍：

SpreadJS 基于 HTML5 标准，支持跨平台开发和集成，支持所有主流浏览器，无需预装任何插件或第三方组件，以原生的方式嵌入各类应用，可以与各类后端技术框架相结合。SpreadJS 以纯前端、跨平台的能力，让应用系统轻松获得与原生
Excel 一致的交互体验。前端集成：

实现效果：

代码实现：

1) : 创建项目

Cmd 依次执行命令:

C:\Users\zhaoQiang\Desktop>vue create spreadjs

C:\Users\zhaoQiang\Desktop>cd spreadjs

安装插件：

npm install 以下插件: 或根据使用需求安装所需要的插件:

3) 监听Excel单元格变化：

// SpreadJs 初始化完毕事件中获取WorkBook对象。
this.designer = value;
this.spread = this.designer.getWorkbook();

监听单元格选中事件和单元格编辑结束事件：
