JQuery單擊編輯帖子和選定的ID不起作用

Question

我正在嘗試編輯帖子。但我有一些問題。

我從codepen.io創建了這個DEMO。

在這個演示中你可以看到有兩個編輯按鈕(red)。當你點擊第一個編輯按鈕時，文本和圖像編輯區將會出現在那裏。但是，如果您檢查開發者控制檯，您可以看到圖像ID不是真實圖像ids。像正常的第一個圖像id="1"和第二個圖像id="2"，但點擊編輯按鈕後，編輯區域圖像ID不是第二個圖像id="2"所有圖像id="1"我的jQuery代碼中有什麼問題。

此外，我怎麼可以把圖片ID從<div class="del" id="here">x</div>
