The removeItem()
method of the Storage
interface, when passed a key name, will remove that key from the given Storage
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.
The following function creates three data items inside local storage, then removes the image
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");
}
