问题 I am about to develop an application where employees go to service repair machines at customer premises. They need to fill up a service card using a tablet or any other mobile device. In case of no Internet connection, I am thinking about using HTML5 offline storage, mainly IndexedDB to store the service card (web form) data locally, and do a sync at the office where Internet exists. The sync is with a MySQL database. So the question: is it possible to sync indexedDB with mysql? I have never

问题 I want to get the callback of a successful SQLite transaction with Ionic 2. I am still currently learning the HTML5 Promise, and it is still a bit confuse. And since I've heavily used jQuery Deferred before, I try to adapt what I used to do with jQuery. Before Ionic 2, I used the following jQuery pattern to execute my async SQL: var SqlResult = function(sqlToExecute,bracketValues){ this.sqlToExecute = sqlToExecute; this.bracketValues =bracketValues; }; SqlResult.prototype

问题 A Cordova/Ionic app I've built is having a little trouble. The problem is only appearing on one user's phone (out of about 6 different phones) Essentially when randomly using the app, sometimes the user will return to the app to find the database / state is completely blank. I have a function that they can trigger to send me the entire db, and it's as if it just randomly resets itself. There is a single call to reset the database, but it is behind a yes/no prompt so I don't think it's user

问题 I'm new to Cordova and currently working with it. I'm creating a login script at the moment, but when I submit a form it looks like the database won't react. The following is what I'm trying to do: When the API's are loaded, create a table and insert a record. When user submits the form, check if the inserted data equals the data of the table. If it matches, go to a new page. I'm not even getting the alert invalid ... when I inserted something useless. I'm getting the success! alert when I

问题 In a normal Android web app the maximum size for a WebSQL database is normally around 8MB. In a hybrid web app I am making I would like to increase this limit. How would I go about doing that? It seems that WebStorage might have something to do with it, but the only method I can see there that seems to set the size, setQuotaForOrigin , is marked deprecated . Sample code (that is not deprecated) is welcome :) 回答1: The quota for a web app seems to differ from that of a hybrid app (as in

I have a local notification plugin set up and what I want to achieve is fetch user setting from web database to set a correct interval for my alarm. 回答1: I have modified the Cordova(https://github.com/Coder-Nasir/incubator-cordova-android) in such a way that it will create the database in Android's Default location which is /data/data/package-name/databases/ By just this simple command window

问题 In windows 7 chrome latestVersion 75.0.3770.80 (Official Build) (64-bit) got an error while get data and write data to chrome browser db in web sql. "unable to begin transaction (3850 disk I/O error)". Do you know any solution to this issue? 回答1: This issue happens if you edit (insert/replace/update) the same data to the same table at the same time. One of the possible cases is you're having 2 tabs opened that access the same database. This is chrome regression since it was working before v75
