This API is available on Firefox OS for internal applications only.
The readOnly read-only property of the DataStore interface returns a boolean indicating whether the current data store is read-only.
Note: The Data Store API is available in Web Workers, from Firefox 32 onwards (Firefox OS 2.0; see bug 949325.)
Syntax
myStoreName = store.readOnly;
Value
A boolean.
Example
The following example gets all the data stores on the device called "contacts", then logs its read-only status to the console:
navigator.getDataStores('contacts').then(function(stores) {
console.log(stores[0].readOnly);
});
