ボタンをクリックすると、関数「DeleteFromlocalStorage」にパラメータ「id」がロードされます。これは私の機能「DeleteFromlocalStorage」です：
function DeleteSessionFromLocalStorage(data)
{
var id_session = data;
a = localStorage.getItem('session');
alert(a);
}
私のalert(a);出力は次のとおりです。

ご覧のとおり、json文字列があります。キーは常に ID です。ここで、id = パラメータ id の json を削除したいと思います。
オブジェクトを取得してサブオブジェクトを削除し、オブジェクトを localStorage に復元する必要があります。どうすればこれができるか知っている人はいますか？
前もって感謝します！
