How to sort alphabetically part of the HTML page (images and text)

Question

I need to order each of the items in the gallery by alphabetical order. Each item would have an image and title.

The code for the gallery:

<section id="content">
<div class="main">
   <div class="container_24">
       <div class="padding-1">
          <div class="wrapper">
              <article class="grid_24">
                  <h4 class="prev-indent-bot">Piante da interno</h4>
                           <div class="wrapper">
                               <div class="col-3 spacing-3">
                                    <div class="border">
                                        <a class="lightbox-image" href="images/Interno/Phalaenopsis_big.jpg" data-gal="prettyPhoto[gallery2]"><img src="images/Interno/Phalaenopsis_small.jpg" width="224" height="208" alt=""></a>
                                    </div>
                                    <div class="bg-title">
                                        <div class="box-padding1">
                                            <h5>Phalaenopsis</h5>
                                        </div>
                                    </div>
                               </div>
                               <div class="col-3 spacing-3">
                                    <div class="border">
                                        <a class="lightbox-image" href="images/Interno/Capelvenere_big.jpg" data-gal="prettyPhoto[gallery2]"><img src="images/Interno/Capelvenere_small.jpg" width="224" height="208" alt=""></a>

                                    <div class="bg-title">
                                        <div class="box-padding1">

                                    </div>

                        </article>
                    </div>
                </div>
            </div>
        </div>
    </section>

Is there a simple solution using javascript or html?

P.S. sorry for my english.

Answer 1

Here's a version that I've tested on the site you've linked:

var articles = $('article.grid_24');
articles.each((art_idx, el)=>{
    var art = $(el);
    var boxes = art.find('.wrapper .col-3'); //Get the boxes that have the image and name

    boxes.removeClass('spacing-3'); //Trim out this, since we don't know if any given box will have this after resorting
    boxes.detach(); //Remove the entries without losing their JS attributes
    boxes.sort((a,b)=>{return ($(b).find('h5').text() < $(a).find('h5').text())?1:-1;}); //Sort by the name in the h5 title

    var wrappers = art.find('.wrapper'); //Get the rows
    var wrapper_idx = -1; //At the very first element, this will be incremented to index 0
    boxes.each((idx, box)=>{ //For each content box
        if(idx % 4 === 0) wrapper_idx++; //For each fourth content box, move to the next row
        if((idx+1) % 4) $(box).addClass('spacing-3'); //If it's not the fourth box, give it back this class
        $(box).appendTo($(wrappers[wrapper_idx])); //Add the content box into the current row
    });
});

Edit: I have changed this to keep the different elements sorted only between their respective article parents.

This can be inserted as a Javascript block after all of the images have loaded. I do agree with Josh Miller in that, ideally, this sorting would actually be done before rendering the content, but the above code should work if the content is already displayed.
