Hello,
I'm looking for an example to save user data directly to a mobile device, such as application settings or custom bookmarks. As I understand, for this purpose commonly used Web SQL. But how to implement this in OE Mobile App Builder?
I would be grateful for a detailed example!
Regards,
Valeriy
Hello Valeriy,
A simple way is to use localStorage object and use the set property and set local storage variable actions when defining events from the Mobile App Builder. The Mobile App Builder also allows you to map local storage variables to parameters as part of a request.
You can also use the localStorage object from JavaScript. Here is some more information.
As part of HTML5, there are some few ways that you can store data locally using JavaScript: localStorage, Web SQL and IndexedDB.
Here are some few links with information on them:
- http://html5demos.com/storage
- diveintohtml5.info/storage.html

For the purpose of settings or custom bookmarks, the simplest approach is to use the localStorage object.
The localStorage object allows you to set and retrieve string data based on a key:
localStorage.setItem(key, value)
localStorage.getItem(key)
You can also use the the following syntax:
localStorage[key] = value;
localStorage[key]
Notice that your value can also be an the string representation of an object by using the JSON.stringify() when storing the value and then JSON.parse() when retrieving it.
Examples:
localStorage["currentPage"] = page;
var page = localStorage["currentPage"]
var myAppSettings = {};
myAppSettings.currentPage = page;
myAppSettings.appMode = 2;
localStorage["myAppSettings"] = JSON.stringify(myAppSettings);
myAppSettings = JSON.parse(localStorage["myAppSettings"])
I hope this helps.
