javascript - 使用jquery修改textarea文本

Question

美好的一天。我如何使用javascript修改textarea输入的文本

我的文本区域中有此内容，我想使用 jquery 删除 PublisherImprintName 标签

  <PublisherInfo>
    <PublisherName>Ask question</PublisherName>
    <PublisherLocation>ph</PublisherLocation>
    <PublisherImprintName>ask stackoverflow</PublisherImprintName>
    <PublisherURL>stackoverflow.com</PublisherURL>
  </PublisherInfo>

可能的输出是

<PublisherInfo>
    <PublisherName>Ask question</PublisherName>
    <PublisherLocation>ph</PublisherLocation>
    <PublisherURL>stackoverflow.com</PublisherURL>
  </PublisherInfo>

是否可以使用 jquery？

我搜索并找到了这段代码，但我不能将其应用于我的问题，但解决方案几乎相似

<script>
$(document).ready(function(){
    $("button").click(function(){
        $("PublisherImprintName").remove();
    });
});
</script>

谢谢。抱歉问了太多问题

另一个问题:

我在这里找到了解决方案:我尝试将它应用到我的问题上，但我无法让它工作

Remove a HTML tag but keep the innerHtml

这是我的文本区域中的文本

  <PublisherInfo>
    <PublisherName>Ask question</PublisherName>
    <PublisherLocation>ph</PublisherLocation>
    <PublisherImprintName>ask stackoverflow</PublisherImprintName>
    <PublisherURL>stackoverflow.com</PublisherURL>
  </PublisherInfo>

和可能的输出

<PublisherName>Ask question</PublisherName>
    <PublisherLocation>ph</PublisherLocation>
    <PublisherImprintName>ask stackoverflow</PublisherImprintName>
    <PublisherURL>stackoverflow.com</PublisherURL>

试试这个

var value = $("textarea").val();
value = value.replace(/<PublisherImprintName( |>).*?<\/PublisherImprintName>/gi,"");
$("textarea").val( value );

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<textarea>
  <PublisherInfo>
    <PublisherName>Ask question</PublisherName>
    <PublisherLocation>ph</PublisherLocation>
    <PublisherImprintName>ask stackoverflow</PublisherImprintName>
    <PublisherURL>stackoverflow.com</PublisherURL>
  </PublisherInfo>
</textarea>
