在 jQuery 中找到最近的兄弟姐妹

[英]finding closest sibling in jQuery

I have the following code in HTML:我在 HTML 中有以下代码:

 $(".remove-post").click((event) => { $(event.target).fadeOut(); }
 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div class="side-bar"> <button class="remove-post"> delete </button> <a class="list"> <p>post title</p> </a> <button class="remove-post"> delete <button> <a class="list"><p>another post title</p></a> </div>

every time that I click on a delete button I want to delete the closest "a" tag with the paragraph inside it as well as the delete button by itself.每次单击删除按钮时,我都想删除其中包含段落的最接近的“a”标签以及删除按钮本身。 I was able to delete the button but can't target the closest a tag to that clicked button I wrote it in jQuery我能够删除按钮,但无法定位与单击按钮最近的标签我在 jQuery 中编写了它

If the button will always stay before paragraph you can do:如果按钮将始终停留在段落之前,您可以执行以下操作:

$(".remove-post").on("click", function () {
    $(this).next(".list").fadeOut()
    $(this).fadeOut()
})

I would recommend you to wrap the paragraph and the button together like:我建议您将段落和按钮包装在一起,例如:

<div class="side-bar">
    <div class="wrapper">
        <button class="remove-post">Delete<button>
        <a class="list">Another post title</a>
     </div>

    <div class="wrapper">
      <button class="remove-post">Delete <button>
      <a class="list">Another post title</a>
    </div>
</div>

If you do so, then you can use this:如果你这样做,那么你可以使用这个:

$(".remove-post").on("click", function () {
    $(this).parent().fadeOut()
})

Assuming you want to remove the next a.list sibling, use .next()假设您要删除下一个a.list兄弟,请使用.next()

 $(".remove-post").on("click", function() { const btn = $(this) btn.add(btn.next("a.list")).fadeOut() })
 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div class="side-bar"> <button class="remove-post">delete</button> <a class="list"><p>post title</p></a> <button class="remove-post">delete</button> <a class="list"><p>another post title</p></a> </div>

jQuery's .add() is used here to collect both the <button> and <a> so you can fade them out together. jQuery 的.add()在这里用于收集<button><a>以便您可以将它们一起淡出。
