Have been doing a codeacademy course http://www.codecademy.com/ru/courses/javascript-lesson-951/0?curriculum_id=4fc3018f74258b0003001f0f#!/exercises/6 - making a vertical sliding pannel.
The problem is that these codeacademy guys didn't explain how to make the pannel not only slide down, but also slide back up. I tried to do it myself, but didnt achieve anything. Please help.
$(document).ready(function(){
ANIMATION_LENGTH = 400;
$panel = $("#panel");
$tab = $("#tab");
var $isShown;
$tab.click(function($isShown){
alert($isShown);
if ($isShown == false)
{$isShown = true;}
else if ($isShown == true)
{$isShown = false;}
var newTop = $isShown == false ? "-180px" : "0px";
var lit = {"top": newTop};
$panel.animate(lit, ANIMATION_LENGTH);
return $isShown
});});
CSS

The click listener gets an event passed, not your boolean.
$(document).ready(function(){
var $isShown,
ANIMATION_LENGTH = 400,
$panel = $("#panel"),
$tab = $("#tab");
$tab.click(function(event){
event.preventDefault();
$isShown = !$isShown;
var newTop = $isShown == false ? "-180px" : "0px";
var lit = {"top": newTop};
$panel.animate(lit, ANIMATION_LENGTH);
});

I'm new to web programming and was hoping to create a system that randomly selects which students are enforced a backpack revision
Recently a student threatened to shoot up the school, it's been 1 month since that event, so the school instead of conducting a search on all students decided to make it totally random, so I decided to create a webpage that does just that.
However, old people will be using it, and although I sorted some of the code out, I wanted to make the website's background red if a revision is due, and green if the outcome of the randomizing algorithm equals a pass.
Here's my code so far:
HTML:
<html lang="en">

<meta charset="UTF-8">

<p id="quoteGenius"></p>
</div><!--end quoteContainer-->
<div id="buttonContainer">
GEN
</div><!--end buttonContainer-->
</div><!--end container-->
</body>
</html>
JS:
$(document).ready(function(){
var quoteSource=[
{
quote: "PASS",
name:"PASS"
},
{
quote:"REVISION",
name:"REVISION"
},
];
$('#quoteButton').click(function(evt){
//define the containers of the info we target
var quote = $('#quoteContainer p').text();
var quoteGenius = $('#quoteGenius').text();
//prevent browser's default action
evt.preventDefault();
//getting a new random number to attach to a quote and setting a limit
var sourceLength = quoteSource.length;
var randomNumber= Math.floor(Math.random()*sourceLength);
//set a new quote
for(i=0;i<=sourceLength;i+=1){
var newQuoteText = quoteSource[randomNumber].quote;
var newQuoteGenius = quoteSource[randomNumber].name;
//console.log(newQuoteText,newQuoteGenius);
var timeAnimation = 100;
var quoteContainer = $('#quoteContainer');
//fade out animation with callback
quoteContainer.fadeOut(timeAnimation, function(){
quoteContainer.html('');
quoteContainer.append('<p>'+newQuoteText+'</p>'+'<p id="quoteGenius">'+'- '+newQuoteGenius+'</p>');
//fadein animation.
quoteContainer.fadeIn(timeAnimation);
});

I just started learning this last week.
Thanks in advance.

Basically, first in your CSS you can make 2 classes, like .pass { background-color: green; } and .revision { background-color: red; } and then in your javascript, test the result of the random generator, and if the result is "pass" then add the class .pass to your <body> element, other wise, if it's "revision", add the class .revision to your <body> element.
Here's modification to your code to make this happen: (Run code snippet)
$(document).ready(function(){
var quoteSource=[
{
quote: "PASS",
name:"PASS"
},
{
quote:"REVISION",
name:"REVISION"
},
];
$('#quoteButton').click(function(evt){
//define the containers of the info we target
var quote = $('#quoteContainer p').text();
var quoteGenius = $('#quoteGenius').text();
//prevent browser's default action
evt.preventDefault();
//getting a new random number to attach to a quote and setting a limit
var sourceLength = quoteSource.length;
var randomNumber= Math.floor(Math.random()*sourceLength);
//set a new quote
for(i=0;i<=sourceLength;i+=1){
var newQuoteText = quoteSource[randomNumber].quote;
var newQuoteGenius = quoteSource[randomNumber].name;
//console.log(newQuoteText,newQuoteGenius);
var timeAnimation = 100;
var quoteContainer = $('#quoteContainer');
//fade out animation with callback
quoteContainer.fadeOut(timeAnimation, function(){
// BACKGROUND COLOR LOGIC HERE
if (newQuoteText === 'PASS') {
document.body.className = 'pass';
} else {
document.body.className = 'revision';
}
quoteContainer.html('');
quoteContainer.append('<p>'+newQuoteText+'</p>'+'<p id="quoteGenius">'+'- '+newQuoteGenius+'</p>');
//fadein animation.
quoteContainer.fadeIn(timeAnimation);
});
break;
};//end for loop
});//end quoteButton function
});//end document ready

I have a page with an initial description, followed by 2 buttons, where the user can choose typeA or typeB. They work by "target": when the user clicks typeA comes the content relative to typeA, bellow the buttons; same to typeB.
typeA is the most common selection, then, when the page loads, a javascript emulates the click to typeA and opens respective content. To avoid hidden the initial description, there is another javascript to put the page at the top. Worked on Chrome and Edge, not on Firefox.
I would like to repeat the same process when the user clicks: opens the respective content, but positioning the page at the top, or, at least, showing the buttons. I thought event onClick calling the same js backToTop would worked - but not.
I put an alert on js and enters there but not execute: always keeps the content of the button selected in its better visibility.
I tried:
window.location.href = '#top';
window.scrollBy(0, -500);
document.html.scrollTop = document.documentElement.scrollTop = 0;
without success.
What am I doing wrong?

You had a real mess there regarding how you process click events and href attribute, i.e:
You had onclick attribute on your links, and you were adding yet another listener to them in JS
You didn't event.preventDefault() in your function, and default browser behavior when you click on a link is to get you to its href path
I've cleaned up a bit and changed some things. Since we need to prevent default behavior :target selector will no longer work, so instead I did what you've already been doing with links, and added an active class to your content. clickHandler() will now remove and add class active as necessary. At the end just scroll to the top. Here's the snippet:
document.querySelectorAll('.target').forEach(targetLink => targetLink.addEventListener('click', clickHandler, false));
function clickHandler(ev) {
ev.preventDefault(); // prevent browser from automatically scrolling to href pos
if (!ev.currentTarget.classList.contains('active')) {
// disable active elements
document.querySelector('.target.active').classList.remove('active');
document.querySelector('.items div.active').classList.remove('active');
// add class to the clicked on button and its corresponding content tab
ev.currentTarget.classList.add('active');
// to prevent pointless string slicing below, you'd have to store ids somewhere else i.e in the data-id attribute
const id = ev.currentTarget.href.slice(ev.currentTarget.href.lastIndexOf('#') + 1);
document.getElementById(id).classList.add('active');
}
window.scrollTo(0,0);
}

Happy Holidays!
Your coding wishes are granted. This is a gift, to you, and you will have to be a good person and post better examples and remember that people are not here to write code for you.
There was a LOT of stuff lacking from your example.
Add items to a list
Update local storage when items are added to a list
Allow list to be sorted
Update local storage when list is updated
Allow task items to be marked completed
Update local storage when items are completed
Allow task items to be deleted
Update local storage when tasks are deleted
Load locally stored tasks
I think that covers everything you wanted this script to do. Is it becoming more clear now?
Working Example: https://jsfiddle.net/Twisty/ae6oLr47/12/
HTML
<iframe src="https://free.timeanddate.com/clock/i5zr5d5i/n1991/szw110/szh110/hoc09f/hbw0/hfc09f/cf100/hnce1ead6/fas30/fdi66/mqc000/mql15/mqw4/mqd98/mhc000/mhl15/mhw4/mhd98/mmc000/mml10/mmw1/mmd98/hhc00f/hhs2/hmcf00/hms2/hsv0" frameborder="0" width="110"
height="110"></iframe>
<div id="container">
<h1>To-do List <i class="fa fa-plus"></i></h1>
<form id="task-list">
<input type="text" placeholder="Add a To-Do" id="task">
<button type="submit"></button>
</form>
<ol id="sortable">
<li id="task-EXAMPLE"><span><i class="fa fa-trash"></i></span>
<label>EXAMPLE</label>
</li>
</ol>
</div>
The first time this loads, there will be no storage, so we can read an examples from the HTML. As you will see, once you make an update, this will no longer be the case.
Q: Why the <button>?
A: <form> likes to have a submit button. It does not need it, yet having it will help a lot in ways I do not want to go into for this question.
JavaScript
$(function() {
$("#sortable").on("click", function(event) {
console.log(event.target);
var $thatItem = $(event.target).parents("li");
switch (event.target.nodeName) {
case "SPAN":
case "I":
$thatItem.fadeOut(500, function() {
$thatItem.remove();
$("#sortable").sortable("refresh");
});
break;
case "LABEL":
$thatItem.toggleClass("completed");
break;
}
setTimeout(function() {
updateLocalStorage($("#sortable"));
}, 500);
event.stopPropagation();
});
$("#task-list").submit(function(event) {
event.preventDefault();
// Grabbing the text typed
var todoText = $("#task").val();
addListItem($("#sortable"), todoText, false);
// Clear the text field
$("#task").val("");
updateLocalStorage($("#sortable"));
});
$(".fa-plus").click(function() {
$("#task-list").fadeToggle();
});
$("#sortable").sortable({
update: function(e, ui) {
updateLocalStorage($(this));
}
}).disableSelection();
function addListItem($t, s, c) {
//create a new LI
var $li = $("<li>", {
id: "task-" + s.replace(" ", "_")
});
if (c) {
$li.addClass("completed");
}
var $wrap = $("<span>").appendTo($li);
$wrap.append($("<i>", {
class: "fa fa-trash"
}));
$li.append($("<label>").html(s));
$li.appendTo($t);
$t.sortable("refresh");
}
function updateLocalStorage($list) {
var tasks = {};
$list.find("li").each(function(ind, elem) {
var task = $(elem).text().trim();
var completed = $(elem).hasClass("completed");
tasks[task] = completed;
if (typeof(Storage) !== "undefined") {
localStorage.setItem("tasks", JSON.stringify(tasks));
}
});
}
if (typeof(Storage) !== "undefined") {
// Code for localStorage/sessionStorage.
if (localStorage.getItem("tasks") !== "undefined") {
var localTasks = JSON.parse(localStorage.getItem("tasks"));
// Grab stored tasks
$("#sortable").find("li").remove();
$.each(localTasks, function(task, status) {
addListItem($("#sortable"), task, status);
});
}
} else {
// Sorry! No Web Storage support..
}
});
You might see that there is very little of your original code left in here. There was just a lot of places to improve the code. I will discuss a bit briefly.
Click Events
Since we're basically listening for click events on the same parent, but want to do different things when specific elements are clicked, that are going to be dynamically created, we can make use of the event.target from the click event. If it's the span or the i that's clicked, we do one thing, if it's the label, another.
The setTimeout is just a way to create a delay in the operations from switch to updating. Otherwise the update will execute almost on top of the switch and will not see the changes to the list, this record no changes.
Submit Event
When you hit Enter or Return you're essentially submitting the form. Part of the reason to add a submit button. Instead of catching the keypress and trying to prevent this, why not just use the submit event to our advantage. This method will help on mobile browsers and such.
Sortable Update Event
When the list is sorted, and updated, we need to update that order in the local storage. Now is the time to do that.
Functions
I think these are pretty clear. You have an operation you will repeat many times, write a function.
Get Item
The last bit of code will load when the page is all ready. It will check for localStorage and check if there are tasks stored within. It will then populate the list with them.
Q: What's with the JSON.stringify()?
A: Yes, you can store stuff locally... only as String. This creates a string version of our object for storage.
Comment if you have other questions.

After making edits in browser, simply save the page as HTML with different file name. Your selected values will be saved.
I am going to add dynamically elements to my block of ul.
I would like to center all list's elements to parent div(brown boder).
For example,
if the resolution of the browser allows you to set two blocks in one row, I would like to center this row in relation to parent div.
I would be very graftefully.

You can use the CSS flexbox to achieve this. Here is a link to a complete guide on how to use flexbox. I hope this helps.
https://css-tricks.com/snippets/css/a-guide-to-flexbox/
Add this lines:
CSS
#wybor_terminu ul {
list-style-type: none;
overflow: hidden;
/*NEW*/
padding: 0;
width: 100%;
}
#wybor_terminu ul li {
width: 200px;
height: 200px;
text-align: center;
color: blue;
border: 0.2em solid green;
/*float: left; You don't need this line*/
cursor: pointer;
/*NEW*/
margin:auto;
margin-top: 40px;
}
EDIT
This is only a quick solution with bootstrap maybe it could help you a little bit. jsfiddle
jQuery
In this line I added bootstrap classes:
$('#godziny').append('<li class="godzina col-sm-12 col-md-6">' + tab[i] + '</li>');
This code center your boxes (is not the best solution, but it works):
countBoxes = $('#godziny').width() / 200;
alignBoxes = ($('#godziny').width()-(200*parseInt(countBoxes)))/2;
if(countBoxes >= 2.65){
$('#godziny').css('margin-left', alignBoxes);
} else{
$('#godziny').css('margin-left', 0);
}
If you change the resolution of your screen, click the button to center your boxes again.
I am designing my website and I'm trying to find a way to keep a header always in the screen.
For an example, take a look at this extra long page on Wikia.com. Notice that when you scroll the page, the little toolbar down the bottom stays in one place. However, scroll to the bottom of the page and you will realize that the toolbar stays in a fixed position until it gets out of view.
This is what I would like to do, but in reverse. Have a header that stays in a fixed position on the web-page, but when it was not in view have it at the top.
I tried looking at an example on DynamicDrive.com (search for Dock Content Script, because I can't post another link), but I found that it was too jittery for me.
Can someone please help me do this?
Thanks in advance.
~DragonXDoom
P.S. Now that I notice, the How to Format box on the right of the submit question page has this effect.
Always remember if you have to stick the header or footer { position : fixed; } can be used.
So apply CSS like this:
.header{
top:0;
width:100%;
height:50px;
position:fixed; // this is the key
}
HTML:
<div id="wrap">
<div id="header"> HEADER </div>
<div id="navigation"> NAVIGATION </div>
<div id="content"> CONTENT </div>
</div>
JavaScript:
( function () {
var nav = $( '#navigation' )[0],
top = $( nav ).offset().top,
left,
height = $( nav ).outerHeight(),
width = $( nav ).width(),
fixedClass = 'fixed';
function pageOffset() {
return window.pageYOffset || document.body.scrollTop;
}
$( window ).
resize( function () {
left = $( nav ).offset().left;
}).
scroll( function () {
$( nav ).toggleClass( fixedClass, pageOffset() > top );
if ( $( nav ).hasClass( fixedClass ) ) {
$( nav ).
css({ 'left': left, 'width': width }).
prev().css({ 'marginBottom': height });
} else {
$( nav ).
prev().andSelf().removeAttr( 'style' );
}
}).
trigger( 'resize' );
})();
Live demo: http://jsfiddle.net/simevidas/Mx8hC/show/
If you want it to be stuck to the top even when the user scrolls (i.e. stuck to the top of the browser window), use:
.top-bar {
position: fixed;
top: 0;
left: 0;
width: 100%;
margin: 0;
}
Or just to the of the the page:
.top-bar {
margin: 0;
width: 100%;
}
You could use CSS positioning to solve this. The following link has instructions on what you need I believe.
http://matthewjamestaylor.com/blog/keeping-footers-at-the-bottom-of-the-page
Edit: Sorry I misread, these should work for headers as well.
http://www.noobcube.com/tutorials/html-css/fixed-header-footer-layout-a-beginners-guide-/
http://davidchambersdesign.com/css-fixed-position-headers/
Hope these help.
