Question

I’ve got a list of elements and I want to use the header divs to separate them after the pages loaded up. So the code below,

<div class="header">Header 1</div>
<div class='test'>Test 1</div>
<div class='test'>Test 2</div>
<div class='test'>Test 3</div>
<div class="header">Header 2</div>
<div class='test'>Test 4</div>
<div class='test'>Test 5</div>
<div class='test'>Test 6</div>
<div class='test'>Test 7</div>
<div class='test'>Test 8</div>
<div class="header">Header 3</div>
<div class='test'>Test 9</div>
<div class='test'>Test 10</div>
<div class='test'>Test 11</div>
<div class='test'>Test 12</div>
<div class="header">Header 4</div>
<div class='test'>Test 13</div>
<div class='test'>Test 14</div>

Would become,

<div class='wrap'>
<div class="header">Header 1</div>
<div class='test'>Test 1</div>
<div class='test'>Test 2</div>
<div class='test'>Test 3</div>
</div>
<div class='wrap'>
<div class="header">Header 2</div>
<div class='test'>Test 4</div>
<div class='test'>Test 5</div>
<div class='test'>Test 6</div>
<div class='test'>Test 7</div>
<div class='test'>Test 8</div>
</div>
<div class='wrap'>
<div class="header">Header 3</div>
<div class='test'>Test 9</div>
<div class='test'>Test 10</div>
<div class='test'>Test 11</div>
<div class='test'>Test 12</div>
</div>
<div class='wrap'>
<div class="header">Header 4</div>
<div class='test'>Test 13</div>
<div class='test'>Test 14</div>
</div>

Any ideas? Thanks in advance.

What you are asking to do is a terrible idea. That’s the kind of stuff you should do server-side. (There are always exceptions).

That being said, the following code should do what you ask.

$('.header').each(function() {
  var head = $(this);

  if(!head.parent().hasClass('wrap')) {
    head.before('div class="wrap"></div>');

    var wrap = head.prev();
    var curr = head;

    do {
      var currEl = curr;
      curr = curr.next();

      currEl.appendTo(wrap);
    } while(curr.length > 0 && !curr.hasClass('header'));
  }
});

NOTE:

I do not usually develop in jQuery, so sorry if I don’t follow whatever the standard way of doing jQuery is.
