Why doesn't my nav bar hide when scrolling down and appear when scrolling up?

So I've tried adapting this http://jsfiddle.net/mariusc23/s6mLJ/31/ code to my webpage so that my nav bar hides when scrolling down and appears when scrolling back up, however it doesn't seem to work and I just can't see the problem, I've included my code below, thanks for the help!
<script>
// Hide Header on on scroll down
var didScroll;
var lastScrollTop = 0;
var delta = 5;
var navbarHeight = $('header').outerHeight();
$(window).scroll(function(event){
didScroll = true;
});
setInterval(function() {
if (didScroll) {
hasScrolled();
didScroll = false;
}
}, 250);
function hasScrolled() {
var st = $(this).scrollTop();
// Make sure they scroll more than delta
if(Math.abs(lastScrollTop - st) <= delta)
return;
// If they scrolled down and are past the navbar, add class .nav-up.
// This is necessary so you never see what is "behind" the navbar.
if (st > lastScrollTop && st > navbarHeight){
// Scroll Down
$('header').removeClass('nav-down').addClass('nav-up');
} else {
// Scroll Up
if(st + $(window).height() < $(document).height()) {
$('header').removeClass('nav-up').addClass('nav-down');
}
}
lastScrollTop = st;
}

<h1>Titanic Movie Review 1996</h1>

<p>
The Titanic is a classic movie filmed in 1996, with jack and rose, it is a classic tradgedy and feautures kate and leonardo da vinci, one is poor, one is rich, the girl has a expensive random amulet that look quite cool i think, yeah, and then the ships crashes and they all die! except for rose. And heres a random movie review from somewhere:<br><br>
Like a great iron Sphinx on the ocean floor, the Titanic faces still toward the West, interrupted forever on its only voyage. We see it in the opening shots of “Titanic,” encrusted with the silt of 85 years; a remote-controlled TV camera snakes its way inside, down corridors and through doorways, showing us staterooms built for millionaires and inherited by crustaceans.<br><br>
These shots strike precisely the right note; the ship calls from its grave for its story to be told, and if the story is made of showbiz and hype, smoke and mirrors--well, so was the Titanic. She was “the largest moving work of man in all history,” a character boasts, neatly dismissing the Pyramids and the Great Wall. There is a shot of her, early in the film, sweeping majestically beneath the camera from bow to stern, nearly 900 feet long and “unsinkable,” it was claimed, until an iceberg made an irrefutable reply.<br><br>
James Cameron's 194-minute, $200 million film of the tragic voyage is in the tradition of the great Hollywood epics. It is flawlessly crafted, intelligently constructed, strongly acted and spellbinding. If its story stays well within the traditional formulas for such pictures, well, you don't choose the most expensive film ever made as your opportunity to reinvent the wheel.<br><br>
We know before the movie begins that certain things must happen. We must see the Titanic sail and sink, and be convinced we are looking at a real ship. There must be a human story--probably a romance--involving a few of the passengers. There must be vignettes involving some of the rest and a subplot involving the arrogance and pride of the ship's builders--and perhaps also their courage and dignity. And there must be a reenactment of the ship's terrible death throes; it took two and a half hours to sink, so that everyone aboard had time to know what was happening, and to consider their actions.<br><br>
All of those elements are present in Cameron's “Titanic,” weighted and balanced like ballast, so that the film always seems in proportion. The ship was made out of models (large and small), visual effects and computer animation. You know intellectually that you're not looking at a real ocean liner--but the illusion is convincing and seamless. The special effects don't call inappropriate attention to themselves but get the job done.<br><br>
The human story involves an 17-year-old woman named Rose DeWitt Bukater (Kate Winslet) who is sailing to what she sees as her own personal doom: She has been forced by her penniless mother to become engaged to marry a rich, supercilious snob named Cal Hockley (Billy Zane), and so bitterly does she hate this prospect that she tries to kill herself by jumping from the ship. She is saved by Jack Dawson (Leonardo DiCaprio), a brash kid from steerage, and of course they will fall in love during the brief time left to them.<br><br>
The screenplay tells their story in a way that unobtrusively shows off the ship. Jack is invited to join Rose's party at dinner in the first class dining room, and later, fleeing from Cal's manservant, Lovejoy (David Warner), they find themselves first in the awesome engine room, with pistons as tall as churches, and then at a rousing Irish dance in the crowded steerage. (At one point Rose gives Lovejoy the finger; did young ladies do that in 1912?) Their exploration is intercut with scenes from the command deck, where the captain (Bernard Hill) consults with Andrews (Victor Garber), the ship's designer and Ismay (Jonathan Hyde), the White Star Line's managing director.<br><br>

I'm currently trying to make a movie review blog post and really want to make everything just stand out, but I'm only relatively new to Css,html and javascript therefore I really can't identify any problems I might have and how to fix them. Again thank you for y'alls help :)

its because you have additional closing tag on line no 15 and 98 in your html, I have fixed that see below demo
var didScroll;
var lastScrollTop = 0;
var delta = 5;
var navbarHeight = $('header').outerHeight();
$(window).scroll(function(event){
didScroll = true;
});
setInterval(function() {
if (didScroll) {
hasScrolled();
didScroll = false;
}
}, 250);
function hasScrolled() {
var st = $(this).scrollTop();
// Make sure they scroll more than delta
if(Math.abs(lastScrollTop - st) <= delta)
return;
// If they scrolled down and are past the navbar, add class .nav-up.
// This is necessary so you never see what is "behind" the navbar.
if (st > lastScrollTop && st > navbarHeight){
// Scroll Down
$('header').removeClass('nav-down').addClass('nav-up');
} else {
// Scroll Up
if(st + $(window).height() < $(document).height()) {
$('header').removeClass('nav-up').addClass('nav-down');
}

Switch visible div based on user click

so I have a div with navigational links (set up using ul/li and a href within the li's).
Below that I have 4 other div's. I only want 1 div shown at a time, they will then switch based on the users selection of the navigational LI's
I've used a similar setup on a different page, and have tried to port it over to my current page but to no avail...

Any help is welcomed, I am still learning (aren't we always), so with any fixes/tips, please detail why it works, or what i did wrong that's making this not work. (if that makes sense!)
Thanks again for your help!

This is one way of achieving it.
HTML - added "navlink" class to your anchor elements, and gave them a data-section attribute that refers to the tab they should show:
<div id="content">
<div class="banner-nav" id="tabs">
<ul class="tabs" style="padding-left: 0px">
<li><span>Home</span></li>
<li><span>Find Your Vehicle</span></li>
<li><span>Downloads</span></li>
<li><a data-section="support" href="#support" rel="support"><span>Support</span></a></li>
</ul>
</div>
<div id="tab-content">
<div id="home" class="tab_content">
1234156124
</div>
<div id="findvehicle" class="tab_content">
abasdjfniasjfnasdf
</div>
<div id="downloads" class="tab_content">
asdfniadhnfiasdn890384834854854jnrjrjr
</div>
<div id="support" class="tab_content">
asdfniadhTHIS IS SUPPORT
</div>
</div>
</div>
JavaScript - see inline comments:
$(document).ready(function(){
// start of at the home page
navigateTo("#home");
// for every navlink element
$('.tabs > li > a').each(function() {
//when it is clicked
$(this).click(function(e) {
e.preventDefault();
// navigate to the section ilinked to in the href
navigateTo($(this).attr('href'));
});
});
});
function navigateTo(sectionId) {
//hide all tabs
$('.tab_content').hide();
//then show the one we want
$(sectionId).show();
}

You don't need separate click handlers for each menu item. The #tabs li click handler will suffice. I removed the click handlers on each of the links since they are not necessary.
$("#tabs li").click(function() {
// First remove class "active" from currently active tab
$("#tabs li").removeClass('active selected');
// Now add class "active" to the selected/clicked tab
$(this).addClass("active selected");
// Hide all tab content
$(".tab_content").hide();
// Here we get the href value of the selected tab
var selected_tab = $(this).find("a").attr("href");
// Show the selected tab content
$(selected_tab).fadeIn(0);
// At the end, we add return false so that the click on the link is not executed
return false;
});

You can try to use css to show and hide the blocks when there is an onclick event.
Here some sample code:
CSS
.activetab {
display: block;
}
.tab {
display: none;
}
JAVASCRIPT / JQUERY
$(document).ready(function() {
$(".tabmenu").on("click", function() {
$(".activetab").removeClass("activetab");
$(this).addClass("activetab");
});
});
HTML
<div id="content">
<div class="man-banner"></div>
<div class="banner-nav" id="tabs">
<ul class="tabs" style="padding-left: 0px">
<li class="active tabmenu"><span>Home</span></li>
<li class="tabmenu"><span>Find Your Vehicle</span></li>
<li class="tabmenu"><span>Downloads</span></li>
<li class="tabmenu"><span>Support</span></li>
</ul>
</div>
<div id="tab-content">
<div id="home" class="tab_content tab">
1234156124
</div>
<div id="findvehicle" class="tab_content tab">

<div id="downloads" class="tab_content tab">
asdfniadhnfiasdn890384834854854jnrjrjr
</div>
<div id="support" class="tab_content tab">

</div>
</div>
</div>
If you want I can create a JSFiddle to see how it works
Hope this works for you!

You have a syntax error, you are closing your document ready callback more than once.
$("#findvehicle").click(function(){
$('a[rel="find_your_vehicle"]').trigger("click");
});
}); // Remove this
$("#downloads").click(function(){
$('a[rel="downloads"]').trigger("click");
});
}); // Remove this
When you remove these extra closes the tabs appear. You'll probably want to hide all but the default tab in that document ready call also.

Uneven Responsive Image/Text Grid with Overlay

I've been trying to create the below layout to no avail. Would someone be kind enough to help me out in either creating a minimal working example or linking to somewhere that would be able to help me out with this?
What I need is a grid where the row heights are the same. With each row containing 2 images and 1 text column (the text column being placed in different locations in each row). The text column needs to be the same height as the images and I'd like the text to be vertically centered but the width of it needs to smaller (half the size). With the images, I'd like to have a white overlay on hover or touch(mobile) with a header and a couple lines for links and one link that will have a video popup (a la fancybox).
I'd like for this to be responsive and adapt to screen sizes. On mobile I'm fine with each box being 100% width but it's the tablet sizes I think I'm having issues with laying this thing out properly. The hover state would obviously need to become a touch state on these platforms.
I'd supply my code if need be but I think I'd like to just start from scratch since I feel like I've just created a huge mess.
I feel like this is something that should be so simple yet I'm having way too many problems with this and I can't seem to find any websites that showcase examples of what I'm trying to create....similar ideas have been found but not exactly what I'm looking for.
Details:
1140px as the max width of the container
444px as the max width of the images
222px as the max width of the text boxes
5px margin/padding
Any help in the right direction would be grateful.

A combination of things here.
Flexbox for the equal heights, max-width where required, paddings/margin for spacing....oh, and positioning for the overlays.

Hide bootstrap panels

I have panel content (not an accordian) setup to be hidden on page load. When a user clicks on one of the tabs, a "hidden" class is removed thus showing the panel content. Then I want to hide the content if the user clicks the tab for the open panel:
$('#section-navigation a').click(function (e) {
e.preventDefault()
if ($(this).closest("li").hasClass("active")) {
$('#section-navigation li.active').removeClass("active");
$(".tab-content").addClass("tab-content-hidden");
} else {
$(".tab-content").removeClass("tab-content-hidden");
$(this).tab('show');
}
});
This does show the panel content on first click, hide the panel content on second click of the same tab but it does not remove the "active" class from the panel content "li", and a third click on the same tab does nothing. Example here (coloured panels):
http://hawk.cloudlevel.me/
Fiddle: https://jsfiddle.net/uvvnpp0s/3/
How can I achieve my goal? I appreciate I might have gone about things in completely the wrong way, as I'm inexperienced with JS / jQuery.

Your custom tabs is conflicting with the bootstrap tabs implementation. Best would be have a custom tab implementation.
Here's a quick custom implementation - https://jsfiddle.net/nitincool4urchat/uvvnpp0s/9/
$("a[role=tab]").click(function() {
if ($(this).parent('li').hasClass('active')) {
$(this).parent('li').removeClass('active');
$(".tab-content").addClass('tab-content-hidden');
} else {
$("#section-navigation li").removeClass('active');
$(this).parent('li').addClass('active');
$(".tab-content").removeClass('tab-content-hidden');
$(".tab-content .tab-pane").hide(); //hide all
$($(this).attr('href')).show(); //show the selected one;
}

Why doesn't the menu background color change?

Problem In JsFiddle

I tested your code and it worked! what is your browser? please place a demo and also add this code as well
a.setAttribute('style','background-color:blue');
some browsers have incompatibility with element.style

give CSS Like this
.arrow_box{ position:absolute; white-space:nowrap}
Check this
http://jsfiddle.net/zz5XJ/2/

try the below HTML:
<body>
<ul class="hMenu">
<li onmouseover="showMenu(this);" onmouseout="hideMenu(this);">
<a style="color: red;" href="javascript:void(0);">prod</a>
<div class="arrow_box" >
<div class="lay1">
<div>Manage Content<br> Message </div>
<br><br>
<div>Manage Assignment<br> User Inquiry</div>
</div>
</div>
</li>
<li onmouseover="showMenu(this);" onmouseout="hideMenu(this);">
<a style="color: red;" href="javascript:void(0);">prod2</a>
<div class="arrow_box">
<div class="lay1">
<div>Manage Content<br> Message <br> Help </div>
<br><br>
<div>Manage Assignment<br> User Inquiry</div>
</div>
</div>
</li>
</ul>
<br/><br/><br/><br/><br/>
Test
</body>

Please check your HTML :
Because you execute same function for both Pord or Pord2 but the Inner html is different for both li. so function showMenu() works different for both Pord or Pord2:
HTML:
<ul class="hMenu">
<li onmouseover="showMenu(this);" onmouseout="hideMenu(this);"><a style="color: red;"
href="javascript:void(0);">prod</a>
<div class="arrow_box">
<br />
<div class="lay1">
<div>
Manage Content<br>
Message
</div>
<br />
<br />
<div>
Manage Assignment<br>
User Inquiry</div>
</div>
</div>
</li>
<li onmouseover="showMenu(this);" onmouseout="hideMenu(this);"><a style="color: red;"
href="javascript:void(0);">prod2</a>
<div class="arrow_box">
<br />
<div class="lay1">
<div>
Manage Content<br>
Message
<br>
Help
</div>
<br />
<br />
<div>
Manage Assignment<br>
User Inquiry</div>
</div>
</div>
</li>
</ul>
Try This
UPDATED
Put <br /> before arrow_box div for both li and some change into Javascript:
var div = obj.children[2];
Javascript -
function showMenu(obj){
var a=obj.children[0];
a.style.color="blue";
var div = obj.children[2];
obj.style.backgroundColor="yellow";
div.style.display="block";
}
function hideMenu(obj){
var a=obj.children[0];
a.style.color="red";
var div = obj.children[2];
div.style.display="none";
obj.style.backgroundColor="";
}
