こんにちは！

ボタンクリックで要素内の値を複数取得し、localstorageに保存したいのですがうまくできません。  
コードが長くなってしまうのでこちらにて失礼します

```

    //クリックに保存する　　のところを
    $("button#save").click(function() {
      var items = $("li img", $("ul", $trash));
      for (var i = 0, len = items.length; i < len; i++) {
          localStorage.setItem(i, $(items[i]).attr("src"));
      }
    
      // 保存されたことを確認する
      for (var i = 0, len = localStorage.length; i < len; i++) {
        $("ul#storedItems").append("<li>" + i + "：" + localStorage.getItem(i));
      }
    });
    
```

これだと問題なく保存されるのですが同時にタグ内のvalue値も保存させたいです  
よろしくお願い致します。

question
javascript jquery jquery-ui
localStorage.setItemで複数の値を保存したい
localStorageに1つのkeyで複数の値を保存する時は[JSON.stringify()](https://developer.mozilla.org/ja/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify)を使うと良いです。  
また、取得時は[JSON.parse()](https://developer.mozilla.org/ja/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse)を使用します。

```

    function set() {
      var object = {
        title: "Title",
        value: "Value"
      }
      // JSON 文字列に変換して保存
      localStorage.setItem("data", JSON.stringify(object));
    }
    
    function get() {
      // オブジェクトに戻して取得
      var object = JSON.parse(localStorage.getItem("data");
      object.title;
      object.value;
    }
    
```
