Scroll to a element onClick JavaScript

So my HTML looks like this :
<section id="nav-wrapper">
<div class="container">
<ul id="ul-main_wrapper">
<li class="item_1""></li>
<li class="item_2"></li>
<li class="item_3"></li>
<li class="item_4"></li>
<li class="item_5"></li>
<li class="item_6"></li>
<li class="item_7"></li>
<li class="item_8"></li>
<li class="item_9"></li>
<li class="item_10"></li>
<li class="close_clear">Back</li>
</ul>
</div>
</section>
I have a list that sits all onto one line so the CSS looks like :
#nav-wrapper {
width: 100%!important;
height: auto!important;
white-space: nowrap;
-webkit-overflow-scrolling: touch;
overflow-x: scroll;
bottom: 80px;
}
#ul-main_wrapper li {
height: 20px;
width: 20px;
margin: 2px;
display: inline-block;
}
onClick of the last item in the list that is back i'm trying to get the list to scroll back to the first item. But can't find anything that works.
EDIT :
Here's a JSFiddle : https://jsfiddle.net/svuh0mvj/1/

Just use scrollTop():
$('.close_clear').on('click', function() {
$(window).scrollTop($('.item_1').offset().top);
})
DEMO
Or with animate:
$('.close_clear').on('click', function() {
var body = $("html, body");
body.stop().animate({scrollTop:$('.item_1').offset().top}, '500');
})
DEMO
To scroll to the left within your #nav-header div, use:
$('.close_clear').on('click', function() {
var nav = $("#nav-wrapper");
nav.animate({scrollLeft: $('.item_1').offset().left}, '500');
})
DEMO

If you are not using jquery, or don't want to use it, you could try to use .scrollIntoView()
MSDN: https://developer.mozilla.org/en-US/docs/Web/API/Element/scrollIntoView
"The Element.scrollIntoView() method scrolls the current element into the visible area of the browser window."
though this is not implemented the same way in all the different browsers we got these days.
document.getElementsByClassName('item_1')[0].scrollIntoView();
Or you could assign an id to the first item, or pass this id: 'ul-main_wrapper' and pass it to this example function
function scrollToAnchor(anchor) {
var scrollLocation = document.location.toString().split('#')[0];
document.location = scrollLocation + '#' + anchor;
}
which will do the scrolling for you.
If you do use jquery, use the solution by mmm

How to animate inserts and removes in a container with justify-content?

Using the flexbox justify-content property, elements can be distributed evenly in their container. However, I want to animate their positions when a new element is inserted or an existing one is removed.
I only managed to animate the height of the elements so far. However, there is a jump at the end of the animation since the gaps around the removed element that got animated to height: 0 vanish. Analogously, when inserting an element there is a jump at the beginning of the animation.
Is it possible to make an animation from end to end with justify-content? Here is an example to play with. Using CSS transition is preferred.

The main problem is that the behavior you are getting is the expected one.
In the very same instant that card.remove() is executed the flexbox justify-content property need to adjust the gaps around the removed element (as you said). And, as Paulie D has pointed out, there is nothing to animate about.
The only solution I can think about is to skip the flex thing and use javascript to create the necessary gaps among the card elements.
Here I leave the snippet:
var animation_time = 500;
var column_height = $('.column').height();
var cards_height = $('.card').height();
var cards_number;
var cards_total_height;
var space_to_be_distributed;
var placeholder_height;
function updateSizes(cards_number)
{
cards_total_height = cards_number * cards_height;
space_to_be_distributed = column_height - cards_total_height;
placeholder_height = space_to_be_distributed / (cards_number + 1);
}
updateSizes($('.card').length);
$('.placeholder').height(placeholder_height);
$(document).on('click', '.card', function () {
var card = $(this);
card.animate({height: 0, opacity: 0}, animation_time, function () {
card.remove();
});
updateSizes($('.card').length - 1);
var placeholder = card.next();
$('.placeholder').not(placeholder).animate({height: placeholder_height}, animation_time);
placeholder.animate({height: 0}, animation_time, function () {
placeholder.remove();
updateSizes($('.card').length);
$('.placeholder').animate({height: placeholder_height}, animation_time);
});
});
$('a').click(function () {
var card = $('<div class="card">');
card.css({opacity: 0, height: 0})
.appendTo('.column')
.animate({height: 25, opacity: 1}, animation_time);
var placeholder = $('<div class="placeholder">');
placeholder.css({height: 0})
.appendTo('.column');
updateSizes($('.card').length);
$('.placeholder').animate({height: placeholder_height}, animation_time);
});
body, html, .column {
height: 100%;
margin: 0;
}
.column {
float: left;
width: 100px;
background: navy;
overflow: hidden;
}
.card {
height: 25px;
width: 100px;
background: grey;
}
.placeholder {
height: 25px;
width: 100px;
}
<html>
<head>
<script src="http://code.jquery.com/jquery-2.1.3.min.js"></script>
</head>
<body>
<div class="column">
<div class="placeholder"></div>
<div class="card"></div>
<div class="placeholder"></div>
<div class="card"></div>
<div class="placeholder"></div>
<div class="card"></div>
<div class="placeholder"></div>
</div>
Add card
</body>
</html>
Hope it helps!
EDIT - I made the following changes in the code:
I change the fiddle for a SO snippet.
I forced an update of elements size at the end of the animation (in case you click to remove an element before the last one has been completely removed)
I change the size of the elementes to adapt it to the (small) SO snippet window.

Selecting child of previous parent jQuery

Lately I've been trying my hand at animation using CSS and jQuery, it went well, however, now I want to do a bit more.
That is, once the user clicks information should show up on top of the image.
At the moment, I just have a few tags on which I perform the animations and class toggles.
My question is, I've thought about doing the following:
<div class= "singleImage">
<img src.... class="actualImage">
<p>text to put over the image</p>
</div>
This would be done per image which means that I'll have about 5 of them with different images.
However, I don't know how to go about selecting the previous element of class "actualImage".
Has anyone got any suggestions?
Thank you

Use the jQuery prev function. Example: Assume you want to select the image previous to the second image:
var foo = $(".singleImage").eq(1);
var bar = $(foo).prev().find('.actualImage');
Fiddle

Try this:
$('singleImage').children('.actualImage').prev();

I'm not sure why you are trying to select the previous element, but you could do something akin to this:
Bind a function to the click event for the element containing your image and caption.
Inside this function, toggle the caption.
Also, bind a click event handler to the body to detect clicks "off" the containing element.
HTML:
<a href="#" class="has-caption">
<img src="http://placehold.it/300x300" />
<span class="caption">This is a caption</span>
</a>
CSS:
a.has-caption { position: relative; }
a.has-caption .caption {
background: rgba(0, 0, 0, .25);
bottom: 0;
color: #fff;
display: none;
height: 20px;
left: 0;
line-height: 20px;
position: absolute;
width: 100%;
}
a.has-caption img { vertical-align: bottom }
JavaScript
$('a.has-caption').on('click', function(e) {
e.preventDefault(); e.stopPropagation();
var self = $(this)
, tmpId = 'toggle-' + Date.now();
self.addClass(tmpId);
$('span.caption', self).toggle();
$('body').one('click', function(e) {
if (!$(event.target).closest('.' + tmpId).length) {
$('span.caption', '.' + tmpId).hide();
self.removeClass(tmpId);
};
});
});

dynamic breadcrumbs using anchor tags and isinViewport

Working on creating a small jquery plugin for a client's website that is a simple breadcrumb system using anchor tags, that changes the last element in the breadcrumb list based on which anchor tag is currently visible. Further, I'm using HTML5 data- elements to store each page name, so that I can add that as the second element in the breadcrumb list as well.
For visibility, I'm using this plugin: https://github.com/zeusdeux/isInViewport
This is the fiddle I'm working with: http://jsfiddle.net/7F59C/4/
Here is the HTML:
<div class="header">head element
<div id="breadcrumbs" data-page="About">
<ul>
<li>Home</li>
<li class="currentpage"></li>
<li class="active"></li>
</ul>
</div>
</div>
<div class="spacer"></div>
<div class="gridContainer">
<div class="space">
take up some space<br />
<a class="crumb" id="About" href="#">About Us</a>
</div>
<div class="space">
take up more space<br />
<a class="crumb" id="Other_heading" href="#">Other heading</a>
</div>
</div>
The JS:
$(document).ready(function() {
$jbread();
});
$.fn.jbread = function () {
//set bc as breadcrumbs list
var bc = $("#breadcrumbs");
//BUILD CURRENT PAGE BREADCRUMB ITEM
//set currentpage to current page's data-page value
var currentpage = bc.data("page");
//set currentpage_link to current page's url
var currentpage_link = window.location.pathname;
//add currentpage as next li in breadcrumbs list
$(".currentpage").html('' + currentpage + '');
//UPDATE ACTIVE ITEM IN BREADCRUMB LIST
$.fn.updateCrumbs = function () {
var currentactive = $(e.target);
$(".active").html(currentactive);
}
//WORK WITH ISINVIEWPORT PLUGIN
$('div.gridContainer > a.crumb').updateCrumbs();
$('div.gridContainer > a.crumb:in-viewport(10)').updateCrumbs();
$(window).scroll(function() {
$('div.gridContainer > a.crumb').updateCrumbs();
$('div.gridContainer > a.crumb:in-viewport(250)').updateCrumbs();
});
//STYLE BREADCRUMB LIST
};
And, for good measure, CSS:
#breadcrumbs ul {
list-style: none;
float: left;
padding: 2px;
}
#breadcrumbs ul li a {
text-decoration: none;
color: black;
}
.space {
height: 500px;
background-color: red;
}
.header {
position: fixed;
height: 100px;
background-color: #FFF;
width: 100%;
margin-top: 0;
}
.spacer {
min-height: 100px;
}
INTENDED FUNCTIONALITY:
As the user is scrolling down the page, when one of the anchor tags with the class "crumb" comes intoViewport (which I have set as 250-350 pixels down the page), I would like the list item with the class of "active" to be updated with the anchor tag that just triggered the function. I'm not sure if I'm using $(e.target) correctly, or if it will even reference the correct thing.
I'm hoping to get this function working, and then I need to create an actual demo page to flesh out styling the list after it is populated. That's for another question.
Any thoughts, comments, or criticisms are welcome as I am very new to jQuery and am questioning my logic on this one.

Looks like you want something like
$.fn.updateCrumbs = function () {
var currentactive = this.text();
$(".active").text(currentactive);
}

Change href when anchor is clicked

I have a question about how I can dynamically change a href="" in a button.
The jsfiddle below shows a button fixed at the bottom of the viewport starting at the landing page:
http://jsfiddle.net/Hm6mA/3/
The html of the button is like so:
<div class="button">
<a href="#first" class="" style="width: 80px; height: 80px; opacity: 1;">
<img src="img/down.png" alt="down">
</a>
</div>
When it is clicked I want it to scroll to the next section and change the href="" to the following section of the page. So, when it is first clicked, the href will change to #second. It would obviously also need to change when the user manually scrolls past a section.
This is for a single page website. How would I go about such a thing?

Use .prop() to change its value
$(".button").on('click', function(){
$('.button').find('a').prop('href', '#services');
});
Demo

You can use fullPage.js plugin to achieve what you want. Maybe it is faster than coding it from cero :)
Demo fullPaje.js
Page

I am not used to jquery. Here is a pure javascript solution. It surely changes the hash value.
<body>
<div id="sections">
<section id="s100">asdfasd</section>
<section id="s101"></section>
<section id="s102"></section>
<section id="s103"></section>
<section id="s104">asdfasdasdfsdf</section>
<section id="s105"></section>
</div>
<div class="nav-bar">
<a id="next-button" class="button" href="#s100">Next</a>
</div>
<script type="text/javascript">
var sections = document.getElementById("sections");
var nextButton = document.getElementById('next-button');
sections.onscroll = function (evt) {
}
var counter = 100;
var limit = 105;
// closure
nextButton.onmouseup = function (evt) {
var incCounter = function () {
// add your custom conditions here
if(counter <= limit)
return counter++;
return 0;
};
var c = incCounter();
if(c != 0)
this.setAttribute('href', "#s" + c);
}
</script>
</body>
CSS
html, body {
height: 100%;
width: 100%;
overflow: hidden;
}
#sections {
height: 50%;
width: 100%;
overflow: scroll;
}
.nav-bar {
margin: 30px 20px;
}
.button {
text-decoration: none;
border: 1px solid #999;
padding: 10px;
font-size: 120%;
}

I have written a small jQuery plugin for that, just pushed it to GitHub. https://github.com/ferdinandtorggler/scrollstack
What you basically want to do is calling
$('.button').scrollstack({stack: ['#first', '#second', ... ]});
You dont even need the link when you call it on the button. So check it out and let me know if it works for you. ;)
Here you can try it and read more: http://ferdinandtorggler.github.io/scrollstack/
