Qn1: the article says.
Qn1：文章说。
The W3C File API includes a FileSaver interface, which makes saving generated data as easy as saveAs(data, filename), though unfortunately it will eventually be removed from the spec.
W3C 文件 API 包括一个 FileSaver 接口，它使保存生成的数据像 saveAs(data, filename) 一样简单，但不幸的是，它最终将从规范中删除。
Why it would be removed?
为什么会被移除？
Qn2: Below code.
Qn2：下面的代码。
if (window.saveAs) {
window.saveAs(blob, name);
}else{
console.log("saveAs not supported")
}
prints
印刷
saveAs not supported
So chrome doesn't support saveAs. That is not the impression I have reading many article online.
所以chrome不支持saveAs。这不是我在网上阅读许多文章的印象。

this is a polyfill, as explained in the article. You have to load the javascript file listed in the article, save it in your resources and link to it in your code: The repository is there: https://github.com/eligrey/FileSaver.js
这是一个 polyfill，如文章中所述。您必须加载文章中列出的 javascript 文件，将其保存在您的资源中并在您的代码中链接到它：存储库在那里：https: //github.com/eligrey/FileSaver.js
There are limitations in Chrome, though. If file already saved, the new saving name is incremented : myFile(1), then myFile(2), etc.
但是，Chrome 中存在一些限制。如果文件已经保存，新的保存名称会增加：myFile(1)，然后是 myFile(2)，等等。
I have now a bug on Chrome, which tells can it cannot OPEN the file, but it is just a false warning, as the file is well SAVED, which is the point.
我现在在 Chrome 上有一个错误，它告诉它不能打开文件，但这只是一个错误的警告，因为文件保存得很好，这就是重点。
