localStorage从本地文件访问 [英] localStorage access from local file

问题描述

我正在创建2个 HTML 文件，这些文件将在本地存储在iPhone中并通过 WebView 进行访问。 / p>

我想知道是否可以在一个文件中设置 localStorage ，并从中获取存储结果其他文件。

我知道可以从同一域上的文件访问 localStorage 但是，看来你好了无法从不同的本地文件中获取值？

我还尝试在桌面上使用本地文件在Safari中运行此操作，并出现同样的问题。

解决方案

在本地打开文件时，即使用 file：// 协议，截至目前，浏览器无法确定什么是相同域，因此每个文件都被视为一个单独的域。因此，当您打开文件时，您无法使用 localStorage 。

以下是有关此问题的更多信息在FireFox中： https://bugzilla.mozilla.org/show_bug.cgi?id=507361 。就个人而言，我在这个主题上找不到很多关于Safari的信息。

你也可以看一下：文件协议下的Javascript / HTML存储选项（文件：//）。它可能对您的情况有所帮助。

I am creating 2 HTML files that will be stored an an iPhone locally and accessed through a WebView.

I am wondering if it is possible to set localStorage in one file, and get the results of the storage from the other file.

I know that localStorage is accessible from files on the same domain, however, it appears that you can not get the value from a different local file?

I have also tried running this in Safari on the desktop with local files and the same issue occurs.

解决方案

When you are opening the files locally, i.e. using the file:// protocol, as of now the browsers can not determine what is "same domain" so every file is considered a separate domain. Thus you can not use localStorage when you're opening the files.

Here is some more information on the problem in FireFox: https://bugzilla.mozilla.org/show_bug.cgi?id=507361 . Personally I couldn't find much about Safari on this topic.

You can also look over this: Javascript/HTML Storage Options Under File Protocol (file://) . It might be helpful in your situation.
