Examples
Log the sampleList
item to the console when the storage
event fires:
window.addEventListener('storage', () => {
// When local storage changes, dump the list to
// the console.
console.log(JSON.parse(window.localStorage.getItem('sampleList')));
});
The same action can be achieved using the onstorage
event handler property:
window.onstorage = () => {
// When local storage changes, dump the list to
// the console.
console.log(JSON.parse(window.localStorage.getItem('sampleList')));
};
