Each entry appearing in the domain property is guaranteed to be unique among the set consisting of the union of every domain key's value out of every record of my object store. I.E. You won't find any of these domains anywhere else in my object store. I need to let user's edit the objects in the object store.
You can also create indices on any object store, provided the object store holds objects, not primitives. An index lets you look up the values stored in an object store using the value of a property of the stored object, rather than the object's key. Additionally, indexes have the ability to enforce simple constraints on the stored data.
Create the CRM database in the IndexedDB. Create the Contacts object store in the CRM database. Insert two records into the object store. If you open the devtools on the web browser, you’ll see the CRM database with the Contacts object store. And in the Contacts object store, you’ll see the data there as shown in the following picture:
To store something in IndexedDB, we need an object store. An object store is a core concept of IndexedDB. Counterparts in other databases are called “tables” or “collections”. It’s where the data is stored. A database may have multiple stores: one for users, another one for goods, etc. Despite being named an “object store ...
So far you've only retrieved objects from the store one at a time. You can also retrieve all of the data, or a subset, from an object store or index using either the getAll() method or cursors. The getAll() method. The simplest way to retrieve all of an object store's data is to call getAll() on the object store or index, like this:
This is very useful when you store objects: put() calls don’t need a second parameter, but can just take the value (an object) and the key will be mapped to the object property that has that name.
An object is a collection of properties. An index is a data structure that operates off the property of several objects. You probably want to store a single object with multiple properties, using only one call to store.put. function addData(data) { var tx = ...; var store = ...; // One call to put that stores all three properties together in ...
It shares five static property values across all instantiations: dbName: the name of the IndexedDB database used for state storage ("stateDB") dbVersion: the database version number (1) storeName: the name of the object store used to store all name/value pairs ("state") DB: a reference to a single IndexedDB object used to access the database, and
