this.someFunction();

</script>

AMD loading. In the <head> section add:

require([

"module/MyWidget"

Object Stores and Data Stores

Prior to 1.6, Dojo used a technology called "dojo/data" to store data. This is now considered a

legacy API that has been superseded by the concept of Dojo Object Stores. An adapter is provided

that maps from the old dojo/data stores to dojo/store stores. This adapter is called

"dojo/data/ObjectStore".

The dojo.store.Memory object is a data store wrapper for arrays of objects.

store = new Memory({

data: <arrayOfData>

});

When using the dojo/store classes, their properties include:

• data – an Array of JavaScript objects being housed in the store

• idProperty – The name of a property to be used as a search key

The resulting store object has the following methods upon it:

• query – Search the store for matching records

• add(object, options) – Add a new record into the store

• remove(id) – Remove an existing record from the store

• put(object, options) – Update an existing row in the store

• get(id) – Retrieve a single object as opposed to "query" which returns an array of

objects
