Storage: removeItem() method - Web APIs | MDN (original) (raw)
The removeItem()
method of the Storage interface, when passed a key name, will remove that key from the givenStorage
object if it exists. The Storage
interface of the Web Storage API provides access to a particular domain's session or local storage.
If there is no item associated with the given key, this method will do nothing.
Syntax
Parameters
A string containing the name of the key you want to remove.
Return value
Examples
The following function creates three data items inside local storage, then removes theimage
data item.
function populateStorage() {
localStorage.setItem("bgcolor", "red");
localStorage.setItem("font", "Helvetica");
localStorage.setItem("image", "myCat.png");
localStorage.removeItem("image");
}
We can do the same for the session storage.
function populateStorage() {
sessionStorage.setItem("bgcolor", "red");
sessionStorage.setItem("font", "Helvetica");
sessionStorage.setItem("image", "myCat.png");
sessionStorage.removeItem("image");
}
Note: To see this used within a real-world example, see our Web Storage Demo.
