wrap content in a div using jquery

问题

I am trying to wrap content in a div but the problem is the html page is not editable so I am trying other way, using jQuery to wrap all the content in a div following is the html structure

$(document).ready(function() {
  $("hr").before("<div class=wrapElement>");
	$("#disqus_thread").before("</div>");
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<hr>
<h4>Title Here</h4>
<p>&nbsp;</p>
<p>&nbsp;</p>
<p>&nbsp;</p>
<div id="disqus_thread"></div>

Problem opening div is placed on correct position, but closing div is not on correct position, it should be above div id="disqus_thread" but its not there, how do I get it placed on this position?

jQuery version is 1.12.4

thanks in advance

回答1:

Use nextUntil() method to get all elements upto the div and use wrapAll() method to wrap them using a div element.

$(document).ready(function() {
  $("hr").nextUntil("#disqus_thread") // get elements from hr upto the previous element of #disqus_thread
       .wrapAll("<div class=wrapElement></div>"); // wrap all elements using div
});

$(document).ready(function() {
  $("hr").nextUntil("#disqus_thread").wrapAll("<div class=wrapElement></div>");
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<hr>
<h4>Title Here</h4>
<p>&nbsp;</p>
<p>&nbsp;</p>
<p>&nbsp;</p>
<div id="disqus_thread"></div>

Or, you can just use built-in jQuery functions:

Here's a fiddle: https://jsfiddle.net/uhr4kuk6/5/

$(document).ready(function() {
$('hr').remove();
  $('h4').wrap('<div class="wrapElement">').prepend('<hr>');
  $('p').each(function() {
  	var getContentWithTags = $(this).clone();
    $('.wrapElement').append(getContentWithTags);
    $(this).remove();
  })
});

.wrapElement {
  background: red;
  padding-top: .5em;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<hr>
<h4>Title Here</h4>
<p>Paragraph 1</p>
<p>Paragraph 2</p>
<p>Paragraph 3</p>
<div id="disqus_thread"></div>

回答3:

If you have a container you can use jQuery wrapInner() method, easly :

$( "body" ).wrapInner( "<div class='wrapElement'></div>");

回答4:

Suppose your content is inside the body tag:

       var mainhtml=  $('body').find('*').not('#thread_content').html()
       $('#thread_content').html(mainhtml);

回答5:

Try this..

<hr>
<h4>Title Here</h4>
<p>&nbsp;</p>
<p>&nbsp;</p>
<p>&nbsp;</p>
<div id="disqus_thread"></div>

$(document).ready(function() {
$("body").wrapInner("<div class=wrapElement></div>");
});
