Represents the list of key/value pairs that have been assigned to a single storage area.

Standards information

• HTML5 A vocabulary and associated APIs for HTML and XHTML

Remarks

Each Storage object provides access to a list of key/value pairs, which are sometimes called items. Keys are strings, and any string (including the empty string) is a valid key. Items contain values (which are also strings) and associated metadata.

Each Storage object is associated with a list of key/value pairs when it is created. Multiple Storage objects, such as two instances of localStorage, can be associated with the same list of key/value pairs simultaneously.

Examples

Key names are exposed as properties on this object. For example, the following statements are equivalent:

sessionStorage.setItem('myKey', '...');
					
sessionStorage['myKey'] = '...'; 
	
sessionStorage.myKey = '...';
