Chrome谷歌浏览器加载ActiveX控件之JT2Go控件

背景

JT2Go是一款西门子公司出品的三维图形轻量化预览解决工具，包含精确3D测量、基本3D剖面、PMI显示和改进的选项过滤器等强大的功能。JT2Go控件是一个标准的ActiveX控件，曾经主要在IE浏览器使用，由于微软禁用IE浏览器，导致JT2Go控件无法使用。因此，网友希望能在谷歌、火狐、Edge等浏览器上使用这个控件。

allWebPlugin中间件是一款为用户提供安全、可靠、便捷的浏览器插件服务的中间件产品，致力于将浏览器插件重新应用到所有浏览器。它不仅可以实现ActiveX控件在现代浏览器上使用，而且集成也非常方便。

准备工作

1、下载allWebPlugin中间件产品，具体如下：

链接：百度网盘请输入提取码
提取码：z3q0

如下图所示，下载allWebPlugin_x86_v2.0.0.22_Stable_20241016.zip安装包。

运行效果

运行效果如下图所示：

控件集成

JT2Go控件主要有3个接口（StartAutomation、Open、StopAutomation），集成代码如下：
