这篇文章介绍如何在web前端引入JS插件实现在线预览、编辑Office文档。
使用插件：Spire.Cloud在线Office文档编辑器（官网：冰蓝科技在线编辑）
重点：该方案仅需浏览器支持HTML5，提供中英文双语界面，不需要安装Office或控件，也不需要做环境配置就可以直接调用插件，非常简单。
准备工作
首先，使用浏览器打开：https://cloud.e-/，点击右上角头像注册/登录账号。
其次，点击菜单栏“我的应用”创建应用，获取APP ID和APP Key。
前端JavaScript代码实现
添加以下JavaScript代码到前端页面，来集成Spire.Cloud在线编辑器实现Office文档在线预览或编辑。参数对照表已放在文章末尾。

以上代码中的appid、appkey参数要更改为你自己的App ID和App Key，"sourceUrl": "https://cloud.e-/demo/sample.docx"参数要改为你自己的文档地址，同时要确保路径存在并且有访问权限。
我这里只是介绍了简单的预览、编辑的前端实现代码，如果需要把文档保存到服务器，需要设置callBackUrl参数（回调URL），这块要配合后端代码去实现。
编辑Word文档效果图如下：
