Trigger play on video when two divs match up

I have created a way to scroll through divs, one has a menu and the others have divs with blanks but one has a video.
At the top of the page is a navigation menu that contains "next", "previous", "reload" and "start".
Those commands are warped in functions,
$("#next-item").on("click", function(){,
The page looks like this:
<div class="webcam-left">
<div class="bottom-panel">
<div class="center" id="content">
<div class="bottom-panel-post internal start"></div>
<div class="bottom-panel-post internal video-post"><video src="https://ia800606.us.archive.org/12/items/ACTV_News_open/ACTV_News_open.mp4"></video></div>
<div class="bottom-panel-post internal"></div>
</div>
</div>
</div>
<div class="nav-right nav-main">
<div class="rundown-panel">rundown</div>
<div class="rundown-items">
<div class="irl-today first"><div class="current">Welcome</div></div>
<div class="irl-today override">Category name</div>
<div class="irl-today">the end</div>
</div>
</div>
</div>
What I'm trying to do is when scrolling down the list, how do you trigger play on a video when a video is shown?
When scrolling down, I added classes to the divs that contain a video.
The left side has .override and the video side has .video-post.
I tried doing if hasClass() but it plays on the first click:
if ( $('.rundown-items').is('.override') ) {
if ($( '.bottom-panel-post' ).has('video')) {
$('video').trigger('play');
};
};
Working code - https://jsfiddle.net/openbayou/paonbxcL/8/

I figured it out, the problem was that it was looking for a class across all items and not each one individually so I added an .each function to look for a class on each individual div.
$(".slider-slide-wrap").each(function (i) {
var posLeft = $(this).position().left
var w = $(this).width();
// add shown class on a div
if (scrollLeft >= posLeft && scrollLeft < posLeft + w) {
$(this).addClass('shown').siblings().removeClass('shown');
}
// if .shown has .play-video, trigger play
if ($('.shown').is(".play-video")) {
$('video').trigger('play');
};
});

How to simultaneously hide and show content and vice versa?

I have a problem and I need your help. I have several links (in <aside>) leading to several different menus (in <section>). On click over the link, only the relevant div in <section> is shown, the rest are hidden. This part is ok and working. What is not working is when I click over an image:
the current div (.menu) in <section> should be hidden;
the same picture (with bigger size) should be shown;
when you click once again over the big image, the big image should disappear and the current div in .menu (the one that was hidden on the first step) should appear one more time. Sort of toggling between content.
So if I click on a picture on the "second div" content, the same picture with bigger size should be show (the "second div" content should be hidden) and when I click once again over the big picture it should disappear and the "second div" content to be returned.
I tried with toggle() but had no success. Either I did not use it correctly, or it is not suitable for my case. This is where I managed to reach to.
I will really appreaciate your support - how to show only the hidden div, not all hidden div's. Right now, when you click on the big image it did not show the hidden div.
$(window).on("load", function() {
$("div.menu:first-child").show();
});
$(".nav a").on("click", function() {
$("div.menu").fadeOut(30);
var targetDiv = $(this).attr("data-rel");
setTimeout(function() {
$("#" + targetDiv).fadeIn(30);
}, 30);
});
var pictures = $(".img-1, .img-2").on("click", function() {
$("div.menu:active").addClass("hidden");
//how to reach out only the current, active div (not all div's in .menu)?
$(".menu").hide();
var par = $("section")
.prepend("<div></div>")
.append("<img id='pic' src='" + this.src + "'>");
var removePictures = $("#pic").on("click", function() {
$(this).hide();
$(".hidden").show();
});
});
.menu {
width: 100%;
display: none;
}
.menu:first-child {
display: block;
}
.row {
display: inline-block;
width: 100%;
}
.img-1,
.img-2 {
width: 120px;
height: auto;
}

Sorry for the ugly sketch and pictures - it is only to get an idea what it should look like....

In general, it's poor form to ask on Stack Overflow how to code for a specific behavior. However, that takes some understanding of the libraries you're using, and what you are trying to achieve. Hopefully, my answer will help you better articulate and form your questions in the future.
Here's a fiddle for you: https://jsfiddle.net/hwd4b0ag/
In particular, I've modified your last click listener:
var pictures = $(".img-1, .img-2").on("click", function() {
var parentDiv = $(this).closest('div.menu').hide();
var blownUpPic = $("<img>").attr({
id: 'pic',
src: this.src,
'data-parent': parentDiv.attr('id')
})
.appendTo("section")
.on('click', function() {
$('#' + $(this).attr('data-parent')).show();
$(this).remove();
});
});
Now, let's review it!
First,
var parentDiv = $(this).closest('div.menu').hide();
In a jQuery listener, the this variable stores the current javascript DOM element that is the recipient of the event listener. In your case, it refers to an element that matches ".img-1, .img-2".
.closest(selector) will traverse up the DOM (including the current element) and find the first matching element for the provided selector. In this case, it finds your container div with class menu. Then we hide that div and save a reference to it in a variable.
Next, we create a full-sized version of the picture and assign it some attributes:
var blownUpPic = $("<img>").attr({
id: 'pic',
src: this.src,
'data-parent': parentDiv.attr('id')
})
We set the data-parent attribute to the id of our container div, so we have a reference back to it later.
We then add our image to the DOM:
.appendTo("section")
And declare a new click listener for it:
.on('click', function() {
$('#' + $(this).attr('data-parent')).show();
$(this).remove();
});
With $(this).attr('data-parent') we use the reference to our container div that we assigned earlier, and then retrieve that element by its id. We unhide the container div and remove the full-sized image.
All done!
There are better ways to code this, but I think this is a good next step for you that's analogous to your current code.

How to create span content on mouse hover?

I want a slider with content. but the content should appear only when mouse hover. This is the code I'm using:
<div id="slideshow" style="width:560px; background:#999;">
<div id="slidesContainer">
<div class="slide">
<img src="js/1.jpg" />
<div> some text </div>
</div>
<div class="slide">
<img src="js/2.jpg" />
<div> some text </div>
</div>
<div class="slide">
<img src="js/3.jpg" />
<div> some text </div>
</div>
<div class="slide">
<img src="js/4.jpg" />
<div> some text </div>
</div>
</div>
</div>
and the jquery 1.8.3 lib and this code
$(document).ready(function(){
var currentPosition = 0;
var slideWidth = 560;
var slides = $('.slide');
var numberOfSlides = slides.length;
// Remove scrollbar in JS
$('#slidesContainer').css('overflow', 'hidden');
// Wrap all .slides with #slideInner div
slides
.wrapAll('<div id="slideInner"></div>')
// Float left to display horizontally, readjust .slides width
.css({
'float' : 'left',
'width' : slideWidth
});
// Set #slideInner width equal to total width of all slides
$('#slideInner').css('width', slideWidth * numberOfSlides);
// Hide left arrow control on first load
manageControls(currentPosition);
// manageControls: Hides and Shows controls depending on currentPosition
function manageControls(position){
if(position >= 4)
{
position=0;
currentPosition=0;
}
// Hide left arrow if position is first slide
if(position==0){ $('#leftControl').hide() } else{ $('#leftControl').show() }
// Hide right arrow if position is last slide
if(position==numberOfSlides-1){ $('#rightControl').hide() } else{ $('#rightControl').show() }
}
function Aplay(){
// Determine new position
currentPosition = currentPosition+1 ;
// Hide / show controls
manageControls(currentPosition);
// Move slideInner using margin-left
$('#slideInner').animate({
'marginLeft' : slideWidth*(-currentPosition)
});
setTimeout(function(){Aplay();},2000);
}
setTimeout(Aplay(),20000);
});
now the <div> some text </div> should appear only when mouse hover, example: http://www.backslash.gr/demos/contenthover-jquery-plugin/#demo4

CSS
<style type="text/css">
.title {visibility:hidden;}
</style>
HTML add a class title to all needed DIV elements
<div class="title"> some text </div>
Add this to your script
$('#slideInner').mouseover(function() {
$('#slideInner .title').css('visibility', 'visible');
});
$('#slideInner').mouseout(function() {
$('#slideInner .title').css('visibility', 'hidden');
});
Working jsBin

A simple solution would be to set up your 'slide' divs like this:
<div class="slide" onMouseOver="$('#TEXT1').css('display','block')" onMouseOut="$('#TEXT1').css('display','none')">
<img src="js/1.jpg" />
<div id="TEXT1" style="display:none;"> some text </div>
</div>

It's easy and i think this is the fastest solution, because require less jquery than the others (= keep your code clean)
Add the following class to every div which contain the description: class="slide-desc" to your HTML
Add var slideDesc = $('.slide-desc'); to your JS, which is just to fit your way of write jQuery, and slideDesc.hide(); (or $('.slide-desc').hide;, to use a faster way instead). This statement (it's better to call the .hide() method in first line of your JS, to avoid the description flashing while page is loading. Put it just after your declaration of variables.
Add somewhere in the JS these lines: $('#slidesContainer').hover(function(){
slideDesc.show();
});
You've done! :D

Slide multiple divs to side as one

I am trying to make navigation bar displayed in a line. For the sake of question I have created this fiddle. I would like to hide the red divs as one div to one side by clicking on the black div. So I put all the red divs into one <div class="box"></div> and tried to slide the box div. But it messes up. Instead of going to a side like a train it expands to multiple rows and then hides. Also I could just slide the divs of class slide but then it looks like this. Which is not what I want, because it hides each one on its own.

This might work for you
FIDDLE
js:
state = true;
$('.clickMe').click(function () {
if (state) {
$("#inner").animate({
left: '-100px'
}, "slow");
state = false;
} else {
$("#inner").animate({
left: '0px'
}, "slow");
state = true;
}
});
html:
<div class="clickMe"></div>
<div id="outer">
<div id="inner">
<div class="slide"></div>
<div class="slide"></div>
<div class="slide"></div>
</div>
</div>

accordion if/else logic

I'm guessing my if/else logic is skewed. Basically I have an accordion structure where, on page load, the first accordion pane is half-revealed to a height of 150px. Then when the user clicks on the accordion header it fully opens to a height of 320px. On the next click it should close and act normally like the other accordion elements with a standard hide/show. It currently works ok but its not smooth and the accordion pane closes before it fully reveals.
Here's the html:
<div class="accordion">
<h3 class="acc-header glanceH">At a glance</h3>
<div class="acc-content glanceC slider" >
<div class="hero-video">
</div>
</div>
<h3 class="acc-header">What we do</h3>
<div class="acc-content" >
<div class="hero-video what-we-do">
</div>
</div>
<h3 class="acc-header">How we do it</h3>
<div class="acc-content how" >
</div>
<h3 class="acc-header">Where we reach</h3>
<div class="acc-content where" >
</div>
<h3 class="acc-header">How</h3>
<div class="acc-content" >
</div>
</div>
Here's the jQuery:
//generally slides all accordion elements with class "acc-content" when div with class "acc-header" is clicked
$('.acc-header').click(function(e) {
e.preventDefault();
$(this).toggleClass('acc-active');
$(this).next('.acc-content').slideToggle(200).siblings('.acc-content').slideUp(200);
$(this).siblings().removeClass('acc-active');
});
//when the page loads 'peek' at the content of the first accordion content (to 150px depth)
$('.slider').css('height','150px');
$('.slider').animate({ height: 'show'}, 'slow').addClass('itsopen');
//if its already been opened, close it, else open it to 320px
$('.glanceH').click(function() {
if(!$(this).hasClass('acc-active')) {
$(this).next().siblings('.acc-content').slideUp(2000);
$(this).siblings().removeClass('acc-active');
}
else if($('.slider').hasClass('itsopen')){
$('.slider').animate({ height: 320}, 'slow');
}
});

Update: Oops, it would help if I read the question - Here is a demo :P
//generally slides all accordion elements with class "acc-content" when div with class "acc-header" is clicked
$('.accordion .acc-header').click(function() {
var first = $('.slider');
// open peek if clicked, otherwise hide it
if (first.is('.itsopen')) {
if ($(this).next().is('.acc-active')) {
// open peek to full height
first.removeClass('itsopen').animate({ height: '320px' }, 'slow');
return;
} else {
// close first because a different header was clicked
first.removeClass('itsopen acc-active').slideUp('slow');
}
}
// remove active class from all content
$('.acc-content').removeClass('acc-active');
// show active content
$(this).next().addClass('acc-active').toggle('slow');
// close all content that isn't active
$('.acc-content:not(.acc-active').slideUp('slow');
return false;
})
// initialize accordion with all content closed
.next().hide();
//when the page loads 'peek' at the content of the first accordion content (to 150px depth)
$('.slider')
.css({ height: '0px' })
.show()
.animate({ height: '150px' }, 'slow')
.addClass('itsopen acc-active');
