Я считаю, что проблема не получается getElementById returns null
но эта строка
var archived = localStorage.getItem("arkiv");
Не могли бы вы указать, действительно ли вы храните значение в localstorage?
Элемент найден, проверьте результат перед ошибкой (ошибка безопасности localstorage, специфичная для stackoverflow)
window.onload = run();
function run(){
console.log(document.getElementById("archivedmovies"));
var archived = localStorage.getItem("arkiv");
console.log(archived)
var array = archived.split(",");
for(var i = 0; i < array.length; i++){
console.log(array[i])
var getUL = document.getElementById("archivedmovies")
console.log(getUL)
var li = document.createElement(li);
li.innerHTML = array[i];
getUL.appendChild(li);
}
};
