如何包装上一个和下一个同级文本<br>用 div 使用 jquery？

Question

Following HTML structure is given and cannot be changed:

 <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>

I want to get to the following result using jQuery:

 <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>

I have tried:

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

But this only wraps the first line:

<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)

Important: There can be one line, two lines, even three lines of text after the <img> Tag.

You need to iterate br element in .default and add your new tag in loop. You can get previous/next text sibling of element using Node.previousSibling and Node.nextSibling property.

$(".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>

Edit:

If your html has multiple <br> , you need to replace br with custom text and after wrap, replace target text to <br> . In example i used [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>

Answer 2

You can ad id to "br", and wrapAll by id list

<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>
