Wrapping a series of elements between two h2 tags with jquery

Question

I currently have a page being dynamically created like below:

<h2>a Heading</h2>
<p>a paragraph</p> 
<p>a paragraph</p>  
<p>a paragraph</p>  
<p>a paragraph</p>  
<p>a paragraph</p>  

<h2>a Heading</h2>  
<p>a paragraph</p>  
<p>a paragraph</p>  
<p>a paragraph</p>  
<p>a paragraph</p>  
<p>a paragraph</p>  

What I'm looking to do is to use jQuery to wrap the h2 and p tags till the next h2 tag: e.g.:

<div class="headingName">
<h2>a Heading</h2>  
<p>a paragraph</p> 
<p>a paragraph</p>  
<p>a paragraph</p>  
<p>a paragraph</p>  
<p>a paragraph</p>
</div>

<div class="headingName">
<h2>a Heading</h2>  
<p>a paragraph</p>  
<p>a paragraph</p>  
<p>a paragraph</p>  
<p>a paragraph</p>  
<p>a paragraph</p>  
</div>

So far I unsuccessfully managed this, but have gotten close using code from a user here (can't find the link to the original article):

$('.report-content h2').each(function(){
    var $set = $();
    var nxt = this.nextSibling;
    while(nxt) {
        if(!$(nxt).is('.report-content h2')) {
            $set.push(nxt);
            nxt = nxt.nextSibling;
        } else break;
    } 
   $set.wrapAll('<div class="content" />');
});

What I get is the div being wrapped around only the p tags but need to include the associated h2 tag, usually the one above the p tags.

Answer 1

Take each h2, grab all sibilings until you get another h2 (or there are no elements at this level) and then reinclude the h2 in the set. Here's the JSFiddle.

$('.report-content h2').each(function(){ 
    $(this)
        .nextUntil("h2")
        .addBack()
        .wrapAll('<div class="content" />');
});

jQuery Documentation

• nextUntil
• addBack
• wrapAll

Answer 2

$('.report-content h2').each(function(){
    var $set = $(this); // this is your key ;)
    var nxt = this.nextSibling;
    while(nxt) {
        if(!$(nxt).is('.report-content h2')) {
            $set.push(nxt);
            nxt = nxt.nextSibling;
        } else break;
    } 
   $set.wrapAll('<div class="content" />');
});
