Animate the scroll between sections on a single page? (javascript only)

I've found a few posts on here similar to what I'm asking, but they all involve jQuery (I'm looking for a solution that's purely javascript, as simple as possible).
I have a page with a fixed nav on the left, where the different links bring you up or down to different sections on the page. It works fine, but I was trying to find a way to animate the scroll. I managed to come up with some javascript that tells me the offset between the sections:
function scroll(e) {
dest = e.target.getAttribute('href');
(for example, this would give me the result of #aboutCon)
destination = dest.replace("#", "");
(this changed it to aboutCon which is already defined as a variable containing the "About" section)
var destOffset = window[destination].offsetTop;
window.scrollTo(0, destOffset);
}
but I have no idea how to take that information and animate it. I've found a few javascript solutions but they're so complicated, whenever I try applying them to my own code, they don't work. I'm hoping there's a simple way to achieve this?
I'm a student and still learning so if you have an answer, an accompanying explanation would be greatly appreciated! Thank you!

document.getElementById("elementID").scrollIntoView();
Or cleaning it up a bit...
function scrollIntoView(eleID) {
var e = document.getElementById(eleID);
if (!!e && e.scrollIntoView) {
e.scrollIntoView();
}
}
Of course replace "elementID" with the ID of the div or element you want to scroll to.
This one is the simplest solution I've found with pure JS.

How to dynamically load generated html with javascript?

I am making a website using HTML, CSS and Javascript. What I'm currently trying to do is making a Javascript that simplifies the way to add more 'items' to a website. For example a store item. Please see http://nl.tinypic.com/r/t5khtf/9.
Those are 3 items that I am adding in this Javascript. However, it keeps telling me that the items are UNDEFINED...
Here is the code from the JavaScript http://pastebin.com/hjL9MByY.
Here is how I load it into a div:
<div id="store_beatles_eps"></div>
How do I fix this?
Any help would be very much appreciated.
If I made any mistakes in the question, please report that to me and I'll change it :).

You use wrong variable. Instead of this:
function generateStoreItem(item)
...
r = r.replace("{{page}}", store_beatles_eps.itemPage);
you should have
function generateStoreItem(item)
...
r = r.replace("{{page}}", item.itemPage);
And yet, while ago I did simple repeatable() jQuery plugin for that purpose:

iTop, where to implement onchange javascript?

the iTop fourms are pretty inactive and I am pretty stuck so I thought I'd ask here if that is ok. I am attempting to add my own piece of javascript to work onchange of the iTop organization select bar.
Here is a link to iTop if needed: http://www.combodo.com/spip.php?page=rubrique&id_rubrique=8
Extra info on my iTop forum question, no answers yet: https://sourceforge.net/p/itop/discussion/922360/thread/dd1da92f/
So iTop is a piece of software made using php, html, js and css but I am new to php so I have ran into a little bit of a problem. I am trying to implement a piece of javascript which will change the top-bar of the css to a different colour based on organization, I made a small prototype independent of iTop and it works perfectly. However I am unable to add the onchange() method along with the javascript as the main user interface is generated dynamically using php. I have tried numerous ways to implement the javascript but none have worked. Here are some pictures of iTop and code to help:
This is a picture showing the inspect element of iTop and how I came to believe jquery-1.7.1.min.js may be the correct location to place the code.
So I have tried going into this file and copy and pasting in my Java Script code but in some locations it has no affect and within function(a){....} it results in iTop only displaying a blank page, I could be going about this totally wrong but from what I have seen this file seems to be the one I am to edit to get what I want.
here is the javascript i am trying to implement:
var changeStyle = function(){
//HTML
var selectedValue = document.getElementById("org_id").value;
//CSS
var trimColor = document.querySelector("#top-bar");
//BT
if(selectedValue=="3"){
//change banner colour
trimColor.style.backgroundColor= "#3498db";
}
//Bell Aliant
else if(selectedValue=="27"){
//change banner colour
trimColor.style.backgroundColor= "#f1c40f";
}
//Bell Canada
else if(selectedValue=="26"){
trimColor.style.backgroundColor= "#e74c3c";
}
else
trimColor.style.backgroundColor="#ecf0f1";
}
Here are some pictures of it working in my non iTop version of just HTML, JS and CSS:

This is an old question but I'll answer it anyway as the answer is still ok for the last versions of iTop.
To inject some JS in the page, you have to use the iPageUIExtension::GetNorthPaneHtml(iTopWebPage $oPage) API which gives you acces to the iTopWebPage object. Then you can use the various public methods such as "iTopWebPage::add_ready_script($sScript)" to inject $sScript into all of the backoffice pages. Moreover, the script will be executed once the DOM is ready.
You can find an example here.
class PageUIExtension implements iPageUIExtension
{
/**
* #inheritdoc
*/
public function GetNorthPaneHtml(iTopWebPage $oPage)
{
...
$oPage->add_linked_script(utils::GetAbsoluteUrlModulesRoot() . 'molkobain-handy-framework/common/js/handy-framework.js');
}
}
Note: You will need to make your own iTop extension, check here for how to do it.

Although I do not believe it is the best solution I have entered the following code into jquery-1.1.1.min.js as shown
And I have achieved the desired result, the trim now changes with the organization change, this however is not the perfect solution I was looking for and is a bit slow but not in the sense that you'd get annoyed, at least in my opinion. Mission Accomplished for the moment!

carousel javascript several times

I wanna use this carousel :
[http://codepen.io/ScottMarshall/pen/FwxpH][1] on a forum, but when I repeat the code, it doesn't work well.
Can you help me ?
here, it's working, but the second container doesn't want and I don't want to change anything in the HTML...
JSFiddle

Here is working fiddle: http://jsfiddle.net/1x6251wc/2/
This is the key change to get the context "Front" instead of all of them:
var $front = $this.parent().find(".Front");
It's a poorly written plugin, but this change should get it to work across multiple instances.

Minimizable side panel in html

I'm looking for a simple javascript to create side panel with hiding after some action(ex. after clicking on some area). Something like this example but appearing from left side not from up to down as the example works.
Will be appreciated for any help :)

You have 2 options. You can either use JQuery or scriptaculous to do this. There are plenty of examples and tutorials on the internet or you can simply use java script to this.
First download émile It's a very simple javascript animation framework.
Since you didn't provide any HTML markup, I'm assuming you have something like this.
<div id="side-panel">panel content..</div>
<div id="content">main content..</div>
and let's say your side-panel element has a CSS style of width:200px. Ok, now place a button somewhere and assign it a click event. Such as onclick="togglePanel()"
Here is the content of the togglePanel function:
function togglePanel(){
var panel = document.getElementById('side-panel');
if(!panel.__closed){
emile(panel, 'width:0px');
panel.__closed = true;
}else{
emile(panel, 'width:200px');
panel.__closed = false;
}
}
If you check the documentation of the emile framework you can do lot's of other cool things.

as you haven't provided us your code (which you have build) that's why I'm just giving a code to help you (And I don't know that this is a right answer or not). This code needs jQuery Ver.1.4 at least I think so, but I'm not clear. Anyways let's get started. Here is a link to live demo.
Hope this helps!
