Windows Phone 8.1 javascript应用程序上未定义的indexedDB [英] undefined indexedDB on Windows Phone 8.1 javascript app

问题描述

我在（HTML / javascript）Windows应用商店应用上有以下代码

I have the following code on a (HTML/javascript) Windows Store app

var reqOpen = window.indexedDB.open(that.dbName, that.dbVersion);

当我想在（HTML / javascript）Windows Phone上使用该确切代码时8.1 app我在 window.indexedDB 上获得 undefined 。

The thing is, when I wanted to use that exact code on a (HTML/javascript) Windows Phone 8.1 app I get undefined on window.indexedDB.

我似乎无法在WinPhone上找到任何与indexedDB相关的示例或任何内容。我发现提到Windows Store和Windows Phone应用程序的唯一文章是这个，但不清楚平台是否存在差异

I can't seem to find any samples or anything related to indexedDB on WinPhone. The only article that I found that mentions both Windows Store and Windows Phone apps is this one, but it is not clear if there's a difference for either 'platform'

我错过了什么？

推荐答案

在Windows Phone 8.1 HTML商店应用程序中无法使用IndexedDB。

IndexedDB is not available on Windows Phone 8.1 HTML store apps.

我写了 SQLite for Windows Apps博客文章提到这一点并描述了如何解决它：在WinRT中包装SQLite并使用它。

I wrote a SQLite for Windows Apps blog post which mentions this and describes how you might work around it: wrap up SQLite in WinRT and use that instead.

博客文章主要是创建自己的，但它也链接到一些现有的项目，这样做和可能有可接受的许可证，包括 SQLite-WinRT 。

The blog post is mostly about creating your own but it also links to some existing projects that do this and that might have acceptable licenses for you, including SQLite-WinRT.

SQLite不一定你唯一的选择，但它是我所知道的唯一一个流行的，已编写VS扩展，并积极支持在Windows商店应用程序中运行。

SQLite isn't necessarily your only option, but it is the only one I know of that is popular, has written VS extensions, and is actively supporting running in Windows store apps.
