我想在没有浏览器要求下载它的 .html 文件中运行 .hta 文件。它应该在浏览器的 html 页面的 iframe 中运行。我使用的代码是这样的-

Actually you can't open a HTAwithin iframeeven if the main app was a HTA. HTAs have their own OS windows, just like a browser or any .exe has.
其实你可以不打开HTA内iframe即使主应用程序是一个HTA。HTA 有自己的操作系统窗口，就像浏览器或任何 .exe 一样。
What you can do, is to put your script to a regular html file. Depending on the security settings of IE, it executes the code, or ask user to allow to execute, or throws an error.
你可以做的是把你的脚本放到一个普通的 html 文件中。根据 IE 的安全设置，它执行代码，或要求用户允许执行，或抛出错误。
Notice also, that ActiveXs work only in Internet Explorer. And like Dark Falcon has said, allowing ActiveXexecution from web would be a huge security risk. So trying to do these kind of things at a public website is not recommended.
另请注意，这ActiveX仅适用于 Internet Explorer。正如 Dark Falcon 所说，允许ActiveX从网络执行将带来巨大的安全风险。因此，不建议尝试在公共网站上执行此类操作。
If this is an intranet app, you can change the main app to HTA. Then you can add Run Notepadbutton (and the script) to the main app, or to an iframe, which has application=yesset. Also trusted sites (html) can run ActiveXs without prompting or errors.
如果这是一个内网应用程序，您可以将主应用程序更改为 HTA。然后您可以将Run Notepad按钮（和脚本）添加到主应用程序，或添加到iframe已application=yes设置的 。受信任的站点 (html) 也可以在ActiveX没有提示或错误的情况下运行。

HTAs cannot be run under the browser. They run under a special host process called mshta. Allowing opening of an HTA in a browser frame would be asking for problems, as HTAs have much higher privileges than normal web pages.
HTA 不能在浏览器下运行。它们运行在一个名为mshta. 允许在浏览器框架中打开 HTA 会带来问题，因为 HTA 具有比普通网页高得多的权限。
