FileReader API在jsFiddle中工作，但不是从本地文件中 [英] FileReader API working in jsFiddle, but not from local file

问题描述

我正在研究将使用文件API在本地存储文件的Chrome / Firefox扩展。我试图让一个例子正常运行，但我遇到了似乎围绕着Chrome的问题。任何人都可以解释为什么这个jsFiddle 工作正常，但完全相同的代码在从本地文件运行时不起作用。请注意，它在Firefox中正常工作，而不是在Chrome中。任何想法？

I'm working on a Chrome/Firefox extension which will be using the file API to store files locally. I'm trying to get an example up and running but I'm running into issues which seem to center around Chrome. Can anyone explain why this jsFiddle works fine, but the exact same code, when run from a local file, doesn't work. Please note that it works fine in Firefox, just not in Chrome. Any ideas?

推荐答案

Chrome具有异常严格的网络安全性;许多事情，如Ajax，在本地运行时都不起作用。这是其中之一。您可以通过使用本地websever解决此问题，例如@ephemient建议，或者您可以在不安全的模式下运行Chrome进行测试：

Chrome has unusually restrictive web security; many things, like Ajax, won't work when run locally. This is one of them. You can get around this problem by either using a local websever, like @ephemient suggests, or you can run Chrome in unsafe mode for testing:

chrome.exe --disable-web-security
