HTML5 local storage not saving correctly
I don't know if I understood the correct "storage" context, but according to some tutorials, I used the following Javascript code to enable the page to store the presented data locally (no session), but when I close the pages and reopen the page, the content is not displayed.
script.js
function initiate()
{
var saveButton = document.getElementById('save');
var retrieveButton = document.getElementById('retrieve');
var deleteButton = document.getElementById('delete');
var reviewButton = document.getElementById('review');
saveButton.addEventListener('click', saveItem);
retrieveButton.addEventListener('click', retrieveItem);
deleteButton.addEventListener('click', deleteItem);
reviewButton.addEventListener('click', reviewAll);
}
function saveItem()
{
var key = document.getElementById('key').value;
var value = document.getElementById('value').value;
localStorage[key] = value;
}
function retrieveItem()
{
var data = document.getElementById('data');
var key = document.getElementById('key').value;
var value = localStorage[key];
data.innerHTML = '<div>' + key + ': ' + value + '</div>';
}
function deleteItem()
{
if (confirm('Delete?'))
{
var key = document.getElementById('key').value;
localStorage.removeItem(key);
data.innerHTML = '<div>Deleted.</div>';
}
}
function reviewAll()
{
for(var i = 0; i < localStorage.length; i++)
{
var key = localStorage.key(i);
var value = localStorage[key];
data.innerHTML += '<div>' + key + ': ' + value + '<br></div>';
}
}
addEventListener("load", initiate);
