Jquery replaceWith not working

问题

Using Jquery 1.7.1

I have two divs

<div class="highlightStart"></div>
{page content here}
<div class="highlightEnd"></div>

Those show up in the page source. But this jquery I added at the bottom of the page is not working:

<script type="text/javascript" id="makeHighlight">
   $(document).ready(function () {
     $("div.highlightStart").replaceWith("<section class='highlight'>");
     $("div.highlightEnd").replaceWith("</section>"); 
   });
</script>

No javascript errors showing in the browser console (Chrome). Just nothing gets replaced.

First i want to site that you're a producing an incorrect structure of DOM. If your script will run it will looks like this:

<div class="highlightStart"><section></div>
{page content here}
<div class="highlightEnd"></section></div>

and this is not a good structure if you want have:

<section>
{page content here}
</section>

Should be something like this:

Your DOM:

<div id="content">
{page content here}
</div>

And in your script:

$(document).ready(function () {
  content = $('#content').text();

  $('#content').html($('<section>').text(content));
});

Please see myfiddle for reference

The replaceWith method expects entire elements, not tags. You'll need to wrap your page contents with a new element, then remove the two original divs.

Update: This might get you close:

$(document).ready(function () {
   $('.highlightStart').nextUntil('.highlightEnd').andSelf()
       .wrap('<section class="highlight"></section>');

    $('.highlightStart, .hightlightEnd').remove();
});

Something's off a bit with this, but I'm out of time. Good luck.

Based on help from isherwood, used this as the solution:

http://jsfiddle.net/H36UE/1/

With HTML tree like this:

<div><div><div class="highlightStart">highlightStart</div></div></div>
<div>Outside<div>Content to Highlight</div>More</div>
<div>second</div>
<div>third</div>
<div><div><div class="highlightEnd">highlightEnd</div></div></div>

This Javascript:

$(document).ready(function () {
  $('.highlightStart').parent().parent().replaceWith("<div class='highlightStart'>");
  $('.highlightEnd').parent().parent().replaceWith("<div class='highlightEnd'>");
  $('.highlightStart').nextUntil('.highlightEnd').andSelf().wrapAll("<section class='highlight'>");

 $('.highlightStart, .highlightEnd').remove();
});
