html5 saveAs支持谷歌浏览器 [英] html5 saveAs support in google chrome

问题描述

我试图按照 saveAs 客户端rel =noreferrer>这里

目前，我只关心Google Chrome，并且使用最新的Canary （版本27.0.1429.0 canary）

Qn1：文章说。

W3C File API包含一个FileSaver接口，它可以节省
生成的数据和saveAs（数据，文件名）一样简单，但不幸的是
它最终会从规范中删除。

为什么会被删除？

Qn2：下面的代码。

  if（window.saveAs）{
 window.saveAs（blob，name）; 
} else {
 console.log（saveAs not supported）
} 
  

打印

  saveAs不支持
  

所以chrome不支持saveAs。这不是我在网上阅读很多文章的印象。

解决方案

这是一个polyfill，正如文章中所解释的。您必须加载文章中列出的JavaScript文件，将其保存在资源中并链接到您的代码中：
存储库位于：
https://github.com/eligrey/FileSaver.js

Chrome中存在一些限制，但是。如果文件已保存，则新的保存名称会增加：
myFile（1），myFile（2）等。

现在有一个错误Chrome，它告诉它它不能打开文件，但它只是一个虚假的警告，因为该文件是很好的保存，这是重点。

I am trying to use saveAs interface as explained here

For the moment, I only worry about Google Chrome, and I uses latest Canary (Version 27.0.1429.0 canary)

Qn1: the article says.

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.

Why it would be removed?

Qn2: Below code.

if (window.saveAs) {
    window.saveAs(blob, name);
}else{
    console.log("saveAs not supported")
}

prints

saveAs not supported 

So chrome doesn't support saveAs. That is not the impression I have reading many article online.

解决方案

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

There are limitations in Chrome, though. If file already saved, the new saving name is incremented : myFile(1), then myFile(2), etc.

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.
