未捕获的语法错误：使用 HTMLCollectionOf时出现意外的标识符

这是给我错误的行：

var modalList = document.getElementsByClassName("modal") as HTMLCollectionOf<HTMLElement>;

这是基于此处，但我的页面将有多个模态图像，因此我更改了一些内容。我发现了许多将 .getElementsByClassName 的返回值转换为 HTMLCollectionOf 的示例，这在我的情况下是必要的，因为我稍后将访问某些属性。如果大多数其他示例都有效，为什么这个示例不行呢？我的脚本标签位于正文的底部。

原文

This is the line that gives me the error:

var modalList = document.getElementsByClassName("modal") as HTMLCollectionOf<HTMLElement>;

This was based off a HowTo tutorial found here, but my page will have multiple modal images so I changed a few things. I found many examples of casting the return value of .getElementsByClassName to HTMLCollectionOf<HTMLElement>, which is necessary in my case since I will be accessing some of the properties later. If most other examples work, why won't this one? My script tag is at the bottom of the body.
