是否有“createObject”？在JavaScript中？ [英] Is there a "createObject" in javascript?

问题描述

在VBScript中有一个名为CreateObject的函数，可以通过网页在客户端上运行。我之前使用过它：

In VBScript there is a function called CreateObject, which can be run on a client through a webpage. I've used it before like this:

Set icaObj = CreateObject("Citrix.ICAClient")
CitrixVersion = icaObj.ClientVersion

找出客户端计算机上安装的应用程序版本。

To find out which version of the application was installed on the client machine.

JavaScript中有类似内容吗？

Is there something comparable in JavaScript?

推荐答案

JavaScript中是否存在类似的内容？

Is there something comparable in JavaScript?

不在 JavaScript 中，但在有限环境下的Microsoft JScript中，是：

Not in JavaScript, but in Microsoft's JScript in limited environments, yes:

var icaObj = new ActiveXObject("Citrix.ICAClient");

就像VBScript一样，这只适用于非常有限的情况：具体来说，有些东西在运行具有完全权限的资源管理器（当然，还有在服务器上运行的JScript中）。

And just like VBScript, this will only work in a very limited situation: Specificially, something running with Internet Explorer with full permissions (or, of course, in JScript running on the server).
