给出了以下 HTML 结构且无法更改： 

<div id="cone" class="team">
  <div class="default"></div>
  ...
  <div class="default">
    <img src="img.jpg" width="271" height="271" alt="" border="0"> First Text line<br> Second text line (optional)
    <img src="img.jpg" width="271" height="271" alt="" border="0"> First Text line<br> Second text line (optional) ...
  </div>
</div>

我想使用 jQuery 得到以下结果：

<div id="cone" class="team">
  <div class="default"></div>
  ...
  <div class="default">
    <img src="img.jpg" width="271" height="271" alt="" border="0">
    <div class="desc">
      First Text line<br> Second text line (optional)
    </div>
    <img src="img.jpg" width="271" height="271" alt="" border="0">
    <div class="desc">
      First Text line<br> Second text line (optional)
    </div>
    ...
  </div>
</div>

我努力了：

$(".team img").each(function () {
    $(this.nextSibling).wrap('<div class="desc"></div>');
});

但这仅包含第一行：

<img src="fileadmin/dateien/bilder/team/platzhalter_team.jpg" width="271" height="271" alt="" border="0">
<div class="desc">First Text line</div>
<br>
Second text line (optional)

<img>重要提示：标签后可以有一行、两行，甚至三行文本。

您需要迭代br元素.default并在循环中添加新标签。您可以使用Node.previousSibling和Node.nextSibling属性获取元素的上一个/下一个文本兄弟。

$(".default > br").each(function(){
    // Store previous/next sibling of br in variable then remove it.
    var prev = $(this.previousSibling).remove()[0].textContent;
    var next = $(this.nextSibling).remove()[0].textContent;
    // Insert new tag before br.
    $(this).before("<div class='desc'>" + prev + "<br>" + next + "</div>");  
}).remove(); // Remove br after loop


$(".default > br").each(function(){
    var prev = $(this.previousSibling).remove()[0].textContent;
    var next = $(this.nextSibling).remove()[0].textContent;
    $(this).before("<div class='desc'>" + prev + "<br>" + next + "</div>");
}).remove();
.desc { color: red }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="cone" class="team">    
    <div class="default"></div> 
    <div class="default">       
        <img src="img.jpg" width="271" height="271" alt="" border="0">
        First Text line<br>
        Second text line (optional)
        <img src="img.jpg" width="271" height="271" alt="" border="0">
        First Text line<br>
        Second text line (optional)
        ...
    </div>
</div>

编辑：

如果您的 html 有多个<br>，则需要将 br 替换为自定义文本，并在换行后将目标文本替换为<br>. 在我使用的示例中[br]。

$(".default").html(function(i, html){
    return html.replace(/<br>/g, "[br]");
});
$(".default > img").each(function(){
    $(this.nextSibling).wrap('<div class="desc"></div>');
});
$(".default").html(function(i, html){
    return html.replace(/\[br\]/g, "<br>");
});


$(".default").html(function(i, html){
    return html.replace(/<br>/g, "[br]");
});
$(".default > img").each(function(){
    $(this.nextSibling).wrap('<div class="desc"></div>');
});
$(".default").html(function(i, html){
    return html.replace(/\[br\]/g, "<br>");
});
.desc { color: red }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="cone" class="team">    
    <div class="default"></div> 
    <div class="default">       
        <img src="img.jpg" width="271" height="271" alt="" border="0">
        First Text line<br>
        Second text line (optional)<br>
        Third text line
        <img src="img.jpg" width="271" height="271" alt="" border="0">
        First Text line<br>
        Second text line (optional)<br>
        Third text line
        ...
    </div>
</div>

您可以将 id 添加到“br”，并通过 id 列表包装所有

<div id="id1">First</div><br id="id2">
<div id="id2">Second</div><br>
<div id="id3">First</div><br id="id4">

<script>
$("#id1,#id2,#id3,#id4").wrapAll("<div class='wraped'></div>")
</script>
