问题 I can't manage to save data using indexedDB in a Firefox extension. I also cannot find any information about indexedDB and Firefox extensions. Has anyone ever dealt with this? 回答1: The only problem is, for indexedDB you need a window, other than that there is not much special when using it from an add-on. Classic add-ons usually have a window that they can use, add-ons created with the Add-on SDK execute in a window-less context however. So if you are using the SDK you use the internal window

问题 A quick overview of what I have, and the problems that are associated with it. I have a HTML5 app that I am going to run as a native app using PhoneGap. It is a small data collection application for the local field research station.

Cool, but now I want to take things a bit further and use indexedDB to cache some dynamic content. Problem is, there's no service-worker.js file to modify. It gets generated during the build process. Is there a way to add additional logic without ejecting create-react-app or redoing all the nice static caching stuff? 回答1: As you've observed,

问题 In my SQL server, I have 64k+ records in a single table. I want to store those records in my client-side IndexedDB database. I thought to create XML files of those data, read those files and save the contents in my IndexedDB. I am getting stuck in reading XML file and saving it to IndexedDB. How can I save an XML file into an IndexedDB database? 回答1: I wouldn't use XML for that. Why don't you write a query that gives you the data in a JSON format? This will be a lot easier to save this into
