SettingsLock.get()

Summary

This method fetches the value of a specified setting.

This method is asynchronous and returns a DOMRequest object, which you use to determine when the request has been completed so that you may act on the results.

Syntax

SettingsLock.get(settingName);

Parameters

settingName

The string name of the setting whose value you wish to retreive. The exact list of possible strings is device dependent. Each Gaia build can have its own list of settings. For an up-to-date list of those strings, take a look at the Gaia source code.

Example

This example checks to see if WiFi is enabled and reports the result.

var lock = navigator.mozSettings.createLock();
var req  = lock.get('wifi.enabled');

req.onsuccess = function () {
  console.log('wifi.enabled: ' + req.result['wifi.enabled']);
}

req.onerror = function () {
  console.log('An error occured: ' + req.error);
}

Specification

Not part of any specification yet; however, this API will be discuss at W3C as part of the System Applications Working Group.
