Your page give a Javascript error: 您的页面给出了Javascript错误：
Uncaught SecurityError: Blocked a frame with origin "mytesturl" from accessing a frame with origin "http://leg.mt.gov". Protocols, domains, and ports must match.
You cannot access the frame's content(or in this case, the scrollheight of the child page) if the protocols, domain or port don't match. 如果协议，域或端口不匹配，则无法访问框架的内容（在本例中为子页面的滚动高度）。
There is a library on GitHub that claims to work: https://github.com/davidjbradshaw/iframe-resizer GitHub上有一个声称可以正常工作的库： https : //github.com/davidjbradshaw/iframe-resizer
Give it a go. 搏一搏。

This is because the frame has a different origin so you can't access the content within it. 这是因为框架的来源不同，所以您无法访问其中的内容。 you'll see a message like this in your inspector: 您会在检查器中看到以下消息：
Uncaught SecurityError: Blocked a frame with origin "http://montanacodeannotated.com" from accessing a frame with origin "http://leg.mt.gov". Protocols, domains, and ports must match.
Perhaps you could pull down a mirror version for your site? 也许您可以为您的网站下载镜像版本？ Running wget -r http://leg.mt.gov/bills/mca_toc/ would recursively copy a version that you could put on your own domain (you might want to ask the origin site first of course!). 运行wget -r http://leg.mt.gov/bills/mca_toc/会递归地复制一个可以放在您自己的域中的版本（当然，您可能要先询问原始站点！）。
Once that was hosted on the same domain, I think the code above would work. 一旦将其托管在同一个域中，我认为上面的代码将起作用。
