こんにちは、度々すみません  
今、monacaを使いドラッグアンドドロップでドロップされた画像をボタンクリックでローカルストレージに保存し、次のページで表示させようとしています。

そこで、ボタンをクリックすると画像（パス）をストレージに保存させようとしていますが  
drop後のtrush内の値を保存させようと

```

    $(function() {
      $("#next").click(onnext);
    });
    
    function onnext() {
        var gazo = $("#trash").html();
        var tes = {
            trash:gazo,  
        }
        console.log("#trush");
    
        localStorage.setItem("test", JSON.stringify(tes));
    }
    
```

このようにしたのですが `#trush` をconsole.logで確認すると

```

    #trush
    {"trash":"\n    \n      Drop Items:1\n      \n    \n  \n      High Tatras\n      \n      \n    "}
    
```

このように表示され画像のパスが入っていません。  
ドロップで `#trush` に画像が入っているから表示されていると思うのですが  
`#trush` 内を取り出すと空に。。。  
どうすればいいでしょうか、よろしくお願い致します。

----- ここまで -----

ドロップした要素の数を取得して表示している

```

    $("#items").text($("li", $("ul", $trash)).length);
    
```

とか、ドロップしている要素

```

    <li class="ui-widget-content ui-corner-tr">
      <h5 class="ui-widget-header">High Tatras 4</h5>
      <img src="hoge" alt="hoge" width="96" height="72">
      <a href="hoge" title="View larger image" class="hoge">View larger</a>
      <a href="hoge" class="hoge">Delete image</a>
    </li>
    
```

をベースに考えると分かりやすいと思います。

例えば、  
`$("li", $("ul", $trash)).length`でドロップした要素数が取れる  
= `$("li", $("ul", $trash))`でドロップした要素が取れる  
といった感じです。
