Expand/collapse excerpt and content

Setting up a simple WordPress blog, that only contains a single page wich is the blog archive. But i have run in to a problem, i want to have a toggle the excerpt and content show more/show less functionality, så that visitors easy can go trough the posts on the same page without page reloads or beeing sent to the single post page. I know this has been asked here before but none of those examples works for me. Just want a simple show/hide functionality to show the excerpt automatic and when users click show more, the whole post slides open to show complete content, and when they click show less, the post goes back to excerpt. I tried most that is here on stack but nothingworks so now i rolled back to my original files to start over. So this script does nothing right now as you se in the loop-custom file. But this is what i have tried.
Here is my js:
$(function () {
$('.mainContent').hide();
$('a.read').click(function () {
$(this).parent('.excerpt').slideUp('fast');
$(this).closest('.post').find('.mainContent').slideDown('fast');
// $('.mainContent').show();
return false;
});
$('a.read-less').click(function () {
$(this).parent('.mainContent').slideUp('fast');
$(this).closest('.post').find('.excerpt').slideDown('fast');
return false;
});
});
Here is my index file:
<div id="content">
<div id="inner-content" class="row">
<main id="main" class="large-8 medium-8 columns" role="main">
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<!-- To see additional archive styles, visit the /parts directory -->
<?php get_template_part( 'parts/loop', 'custom' ); ?>
<?php endwhile; ?>
<?php joints_page_navi(); ?>
<?php else : ?>
<?php get_template_part( 'parts/content', 'missing' ); ?>
<?php endif; ?>
</main> <!-- end #main -->
<?php get_sidebar(); ?>
</div> <!-- end #inner-content -->
</div> <!-- end #content -->
And here is my loop-custom file:
<article class="post" id="post-<?php the_ID(); ?>" <?php post_class(''); ?> role="article">
<header class="article-header">
<?php get_template_part( 'parts/content', 'byline' ); ?>
<h2><?php the_title(); ?></h2>
</header> <!-- end article header -->
<section class="entry-content" itemprop="articleBody">
<?php the_post_thumbnail('full'); ?>
<?php the_excerpt('<button class="tiny">' . __( 'Show more...', 'jointswp' ) . '</button>'); ?>
</section> <!-- end article section -->

EDIT: Answer updated after testing in fiddle.
<div class="post-wrap">
<h2>The Title</h2>
<div class="post">
<div class="excerpt">
Excerpt goes here
</div>
<div class="whole-post">
Slidey read more content goes here
</div>
Read More
</div>
</div>
.whole-post {
display: none;
}
.post {
position: relative;
padding-bottom: 50px;
}
a.read {
position: absolute;
bottom: 10px;
right: 10px;
}
$('a.read').click(function () {
$(this).siblings('.excerpt').slideToggle(500);
$(this).siblings('.whole-post').slideToggle(500);
});
Further comment asking about changing "read more" button text on click - requires additional line of jQuery, like so:
$('a.read').click(function () {
$(this).siblings('.whole-post').is(':visible') ? $(this).html('Read More') : $(this).html('Read Less');
$(this).siblings('.excerpt').slideToggle(500);
$(this).siblings('.whole-post').slideToggle(500);
});
jsfiddle here.
Note: The ternary query ? truthy : falsey ; syntax is short for if (query) { truthy } else { falsey } ;

Making a <div> Clickable in Wordpress

I'm working on modifying an existing wordpress portfolio page. All that is left to do is to make it so when the user clicks anywhere in the article list the link will open. Currently it is just when the title or image is clicked.
I can see that I could make a clickable with the following setup:
<a href="http://example.com">
<div>
anything
</div>
</a>
However Wordpress moves the tags when the page loads like so:
<a href="http://example.com">
</a>
<div>
anything
</div>
So I started to work on using css with the following setup:
HTML
<div class= "box">
</div>
CSS
div.box {
position: relative;
}
div.box:hover {
cursor: hand;
cursor: pointer;
opacity: .9;
}
The hover works, it triggers over all of the content and a cursor does appear.
However thats as much as I can do so far. Any attempt to interact with the .box is shot down. Nothing will trigger with javascript using the following :
$(".box").click(function() {
alert("I am an alert box!");
});
I cannot seem to interact with the div.
The page is as follows:
<div class= "box">
<article id="post-<?php the_ID(); ?>" class="portfolio-article clearfix">
<?php if( get_post_meta($post->ID, "portfolio_image", true) ): ?>
<img src="<?php the_field('portfolio_image'); ?>" class="portfolio-image">
<!--get PDF if not empty-->
<?php else: ?>
<img src="http://domain.com/wp-content/uploads/2014/02/placeholder.png" class="portfolio-image">
<?php endif; ?>
<div class="portfolio-content">
<header>
<?php if( get_post_meta($post->ID, "portfolio_link", true) ): ?>
<h1 class="portfolio-title">
<a target="_blank" href="<?php the_field('portfolio_link'); ?>">
<?php the_field('portfolio_title'); ?> <span class="sosa-icon">p</span>
</a>
</h1>
<!--get PDF if not empty-->
<?php else: ?>
<h1 class="portfolio-title"><?php the_field('portfolio_title'); ?></h1>
<?php endif; ?>
</header>
<p class="portfolio-meta">
<?php the_field('portfolio_publication_and_date'); ?>
<?php if( get_post_meta($post->ID, "portfolio_pdf_upload", true) ): ?>
<span class="sosa-icon">H</span> Open Pdf<!--get PDF if not empty-->
<?php endif; ?>
</p><!-- END ortfolio-meta -->
</div><!--portfolio-content-->
</article>
</div>

NewToJS was in the right area when saying it could be a problem with the access to the jQuery library. In this case I had linked jQuery correctly, it was tested and working.
jQuery in Wordpress needs to be enqueued by adding the following into functions.php
wp_enqueue_script("jquery");
My fault was because I didn't change the '$' to 'jQuery' as this is necessary when working with Wordpress.
Here is the incorrect usage :
$(".box").click(function() {
alert("I am an alert box!");
});
Here is the correct usage :
jQuery(".box").click(function() {
alert("I am an alert box!");
});

a element inside of article tag gets duplicated 10 times all of them getting the same classes, ids etc

tl;dr; Some javascript that runs in wordpress duplicates my top element all over the html. See image.
Hi
I am really surprised at this bug in wordpress, and its actually pretty easy to replicate. I wanted a
<a class="something" href="a-link"> ... </a>
to wrap all of my article content so that it would look like this code:
<article id="post-<?php the_ID(); ?>" <?php post_class('col-md-4'); ?>>
<a class="hehe" href="google.com">
<?php
if (is_sticky() && is_home() && ! is_paged()) {
printf( '<span class="sticky-post">%s</span>', __('Featured', 'nisarg'));
} ?>
<?php nisarg_featured_image_disaplay(); ?>
<div class="main-image">
<?php if( get_field('main_image') ): ?>
<img class="img-responsive " src="<?php the_field('main_image'); ?>" />
<?php endif; ?>
</div>
<?php if( get_field('vacation_type_image') ): ?>
<img src="<?php the_field('vacation_type_image'); ?>" class="post-vacation-type" />
<?php endif; ?>
<header class="entry-header">
<div class="post-header">
<div class="row blog_post_container">
<div class="col-sm-12 blog_post_info_container_col">
<div class="blog_post_info_container">
<div class="blog_post_info_container_margin">
<span class="screen-reader-text"><?php the_title();?></span>
<?php if( is_single()) : ?>
<h1 class="entry-title blog_post_header"><?php the_title(); ?></h1>
<?php else : ?>
<h2 class="blog_post_info entry-title">
<?php the_title(); ?>
</h2>
<?php endif; // is_single() ?>
<?php if ('post' == get_post_type()) : ?>
<div class="entry-meta">
<h5 class="blog_post_info entry-date"><?php nisarg_posted_on(); ?></h5>
</div><!-- .entry-meta -->
<?php endif; ?>
</div>
</div>
</div>
</div>
</div>
</header><!-- .entry-header -->
<div class="entry-summary row">
<div class="excerpt">
<?php the_excerpt(); ?>

I am using the Nisarg theme, but if i went inside of twentysixteen theme, and put a:
<a class="something" href="a-link"> ... </a>
inside of that content.php it would have the same effect, it litters the element inside of the article. like this:
If i look in the source code of my web page, i dont see any of these additional A elements, so they're being appended by some javascript. Now that its something that occurs in several themes i think it has something to do with html5shiv... But ive tried to remove that script from the equation, but the problem remains - so im kind of lost. Does anyone know which javascript library that could do something like this?? i have also used grep to look for javascript files that does a.cloneNode but to no prevail.
Twentysixteen, replication of error:

'</span>'
);
?>
</footer><!-- .entry-footer -->
</a>
</article><!-- #post-## -->
Resulting html:
so that means, simply adding a a tag right after the article tag in something like content.php will duplicate the a tag inside of all the divs, which just seems insane to me.
Thanks
EDIT 1: adding example of "core" wordpress theme twentysixteen with exact same error.
EDIT 2: I can confirm, a clean installation of Wordpress has this exact problem.

There is another <a> within the <h2> title. It's not possible to nest <a> tags.
If you do this, the browser attempts to fix the structure closing the nested <a> and what you see is the result.

Slides not showing on flexslider

I'm building a new homepage WordPress template. The template uses Flexslider to display Vimeo videos, a simple title and description.
I've followed the FlexSlider documentation to the letter, but the slides are all coming up blank.
Here's what I'm seeing via the Chrome Inspector:
.flexslider .slides > li {
display: none;
-webkit-backface-visibility: hidden;
}
For some reason the JQuery isn't kicking in. I've tried removing the inline styles from the <li> tags. I've also tried knocking out the lightbox script that I have running. Nothing seems to be working.
Can you see what's causing this? I've uploaded a demo here: http://bit.ly/1Sgpu99
UPDATE
Here's the relevant source from the template:
<?php // Begin main loop
while ( have_posts() ) : the_post(); ?>
<?php // Begin carousel repeater
if( have_rows('slides') ): ?>
<div class="flex-container">
<div class="flexslider">
<ul class="slides">
<?php while( have_rows('slides') ): the_row();
// vars
$background_image = get_sub_field('background_image');
$video = get_sub_field('video');
$title = get_sub_field('title');
$description = get_sub_field('description');
$background_image = get_sub_field('background_image');
?>
<li class="slide" style="background: url(<?php echo $background_image; ?>) no-repeat center; background-size: cover;">
<div class="container">
<div class="half">
<div class="video"><?php echo $video; ?></div>
</div>
<div class="half last">
<header class="entry-header">
<h1 class="entry-title"><?php echo $title; ?></h1>
</header>
<?php echo $description; ?>
</div>
</div><!-- .container -->
</li>
<?php endwhile; ?>
</ul>
</div><!-- .flexslider -->
</div><!-- .flex-container -->
<?php // End repeater
endif; ?>
<?php // End main loop
endwhile; ?>

For some reason flexslider has not been initialized in your page.
If you put this code in Chrome or Firefox console
jQuery(".flexslider")
.flexslider({
animation: "slide",
useCSS: false,
animationLoop: false,
smoothHeight: true,
before: function(slider){
$f(player).api('pause');
}
});
and hit enter, the slider is showing ( whit completely broken css, but this is another question :) )
I can't tell from provided code why slider is not initialized, but you must debug your .js code, not .php. Put some console.log() in .js file where slider is initialized, to be sure that file is loaded, use wp_enqueue_script() to load your .jsfiles with proper dependence to be sure that files are loaded in proper order and so on.

If child page has content, enable link, else disable link

I am working on a mosaic of thumbnails linking to child pages. The code works in such a way that the child pages display in an iframe overlaying the content. However the client wants only 4 of these pages to have content, so the code needs to work in such a way that ONLY if the child page has content, does the rollover get enabled to open as an iframe overlay.
I currently have the following code. Any ideas how i could customise it so that the overlay is enabled ONLY if the child page has content? Many thanks.
<section id="content" role="main">
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
<section id="content_team" class="entry-content js-masonry">
<?php $child_pages = $wpdb->get_results("SELECT * FROM $wpdb->posts WHERE post_parent = " . $post->ID . " AND post_type = 'page' ORDER BY menu_order", 'OBJECT'); ?>
<?php if ($child_pages) : foreach ($child_pages as $pageChild) : setup_postdata($pageChild); ?>
<div class="child-thumb">
<div id="click_overlay" onclick="var overlay = document.getElementById('hidden_overlay');
overlay.src = 'about:blank';
overlay.style.display = 'block';
overlay.src = '<?php echo get_permalink($pageChild->ID); ?>';"><span class="featured-title-overlay">
<span class="featured-title">
<span class="title"><?php echo get_the_title($pageChild->ID); ?></span>
<div class="hr"> </div>
<span class="title_link">Read more...</span>
</span>
</span><?php echo get_the_post_thumbnail($pageChild->ID); ?></div>
<br class="clear" />
</div>
<?php endforeach;
endif;
?>
</section>
</article>
<?php endwhile;
endif; ?>
<iframe id="hidden_overlay" src="about:blank"></iframe>
<p class="clear"> </p>
</section>
