私は11級のコンピュータープログラマーで、JSON割り当てを完了しようとするといくつかの問題が発生しました。目標はオブジェクトをローカルストレージに保存することですが、私のhtmlとjsはそうしません。代わりに、何も起こりません。すべてのフィードバックは高く評価されます。JSON Javascript＆HTML

var announcement = {

var x = JSON.stringify(announcement);
localStorage.setItem('announcement', x);
}
function showAnnouncement(){
var obj = localStorage.getItem('announcement').value;
var obj2 = JSON.parse (obj);
document.getElementById('showAnnouncement').innerHTML = "title:" + obj2.title
