Possible solution:
可能的解决方案：
You need to register your dll at the destination computer. Than in js you need to create ActiveX object with the same registered name
您需要在目标计算机上注册您的 dll。比在 js 中您需要创建具有相同注册名称的 ActiveX 对象
var ObjFromDll = new ActiveXObject("DllRegisteredName");
and call it's method.
并调用它的方法。
var anyResult = ObjFromDll.MyMethod()
