如何包装< br>的上一个和下一个同级文本.使用jQuery的div? [英] How to wrap previous and next sibling text of <br> with div using jquery?
问题描述
已给出以下HTML结构,无法更改:
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>
我想使用jQuery获得以下结果:
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>
我尝试过:
$(".team img").each(function () {
$(this.nextSibling).wrap('<div class="desc"></div>');
});
但这仅包装第一行:
<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)
重要提示:<img>
标记后可以有一行,两行甚至三行文字.
Important: There can be one line, two lines, even three lines of text after the <img>
Tag.
推荐答案
您需要迭代.default
中的br
元素,并在循环中添加新标签.您可以使用 Node.previousSibling
和 Node.nextSibling
属性.
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 }

<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>
如果您的html有多个<br>
,则需要用自定义文本替换br,然后换行,然后将目标文本替换为<br>
.在示例中,我使用了[br]
.
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>
