[name: string]: any

Properties

readonly

length: number

Returns the number of key/value pairs currently present in the list associated with the object.

Methods

clear(): void

Empties the list associated with the object of all key/value pairs, if there are any.

getItem(key: string): string | null

Returns the current value associated with the given key, or null if the given key does not exist in the list associated with the object.

key(index: number): string | null

Returns the name of the nth key in the list, or null if n is greater than or equal to the number of key/value pairs in the object.

removeItem(key: string): void

Removes the key/value pair with the given key from the list associated with the object, if a key/value pair with the given key exists.

setItem(key: string, value: string): void

Sets the value of the pair identified by key to value, creating a new key/value pair if none existed for key previously.

Throws a "QuotaExceededError" DOMException exception if the new value couldn't be set. (Setting could fail if, e.g., the user has disabled storage for the site, or if the quota has been exceeded.)
