How to fade out text using JavaScript or jQuery and then bring it back

I am new to JavaScript/jQuery and what I want to do is to fade out text and when the opacity is zero, I want to bring back the text with the same effect. I am leaning towards some kind of if statement and the fade in effect, but don't manage to understand how to put it all together. Any tips for how this could be done using jQuery would be appreciated.
function hideText() {
var fadeText = document.getElementById("fadeTextp");
fadeText.style.opacity = 0;
fadeText.addEventListener("transitionend", function(e) {
alert("The text is hidden, but how can I now get it back with same effect?")
}, false);
}
.fade {
opacity: 1;
transition: opacity 2.25s ease-in-out;
-moz-transition: opacity 2.25s ease-in-out;
-webkit-transition: opacity 2.25s ease-in-out;
}
<p id="fadeTextp" class="fade" onclick="hideText();">
Fade out this text and then bring it back when clicked again.
</p>

I'm not sure what your overall goal is, but there are lots of ways to do this kind of thing. Some could use only CSS, some could use JavaScript, some could use both. I'll do a "both" example.
Note: It would probably be better to use one or the other - so you don't define the transition time in both places.
Note: jQuery has animation support built in. See the answer from #Twisty for a jQuery example and links to their docs.
var transitionTime = 2250;
var faderTimeout = null; // keep track of this to cancel it if multiple events happen
var fadeText = document.getElementById("fadeTextp");
function hideText() {
fadeText.classList.remove('out');
fadeText.classList.add('out');
window.clearTimeout(faderTimeout);
faderTimeout = window.setTimeout(() => {
fadeText.classList.remove('out');
}, transitionTime);
}
.fade {
opacity: 1;
transition: opacity 2.25s ease-in-out;
-moz-transition: opacity 2.25s ease-in-out;
-webkit-transition: opacity 2.25s ease-in-out;
}
.fade.out {
opacity: 0;
}
<p id="fadeTextp" class="fade" onclick="hideText();">
Fade out this text and then bring it back when clicked again.
</p>

Here's a jQuery example since you asked for jQuery. You need a container with some height to be able to click again for the text to come back. If you don't have this container then the thing you add a "click" event listener to is not available to click anymore.
I use the :visible selector to see if the text is visible and if so fadeOut and if it's not visible then fadeIn.
let fadeTextp = $("#fadeTextp");
$("#fadeTextContainer").on("click", () => {
if (fadeTextp.is(":visible")) {
fadeTextp.fadeOut()
} else {
fadeTextp.fadeIn()
}
});
#fadeTextContainer {
height: 50px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="fadeTextContainer">
<p id="fadeTextp">
Fade out this text and then bring it back when clicked again.
</p>
</div>

Here is a quick jQuery Example.
$(function() {
$(".fade").click(function() {
var $this = $(this);
$this.fadeOut(600, function() {
$this.fadeIn(600);
});
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<p id="fadeTextp" class="fade">
Fade out this text and then bring it back when clicked again.
</p>
This uses .fadeOut() and cascades a callback to .fadeIn().
See more:
https://api.jquery.com/fadeout/
https://api.jquery.com/fadein/
You can also animate the visibility.
$(function() {
$(".fade").click(function(e) {
var t = $(this);
if (t.hasClass("out")) {
t.animate({
opacity: 1
}, 600);
t.removeClass("out");
} else {
t.animate({
opacity: 0
}, 600);
t.addClass("out");
}
});
});

<p id="fadeTextp" class="fade">Fade out this text and then bring it back when clicked again.</p>

How to turn this CSS with plain javascript or jQuery instead of hover to on click

HTML
<div class="flip3d">
<div class="back" >Box1-I</div>
<div class="front">Box1-Front</div>
</div>
<div class="flip3d">
<div class="back" >Box2-back</div>
<div class="front">Box2-Front</div>
</div>
<div class="flip3d">
<div class="back" >Box3-back</div>
<div class="front">Box3-Front</div>
</div>
CSS
.flip3d{
width:200px;
height;200px;
margin:10px;
float:left;
}
.flip3d>.front{
position:absolute;
transform:perspective(600px)rotateY(0deg);
background:#FC0; width:200px; height:200px; border-radius:6px;
backface-visibility:hidden;
transition: transform 1s linear 0s;
}
.flip3d>.back{
position:absolute;
transform:perspective(600px)rotateY(180deg);
background:lightgreen; width:200px; height:200px; border-radius:6px;
backface-visibility:hidden;
transition: transform 1s linear 0s;
}
JS
$(function(){
$('.flip3d').on('click',function(){
if($(this).children('.front')) {
$(this).children('.front').css({'transform':'
perspective(600px)rotateY(-180deg)'});
if($(this).children('.back')) {
$(this).children('.back').css
({'transform':'perspective(600px)rotateY(0deg)'});
}
});
});
what i want to do is to make the div flip the same exact thing but on click instead of hover to be compatible with touch screen it might be noob question for some of you
thanks in advance:)
Edited :
thanks to #AaronEveleth logic
i have found the solution with jQuery now when i click it flip to back but when i click again it doesn't go to front again any suggestion why?

Where you currently have the code inside the :hover blocks, you can change the block to a different class, something like click-class. Here is an example of how you can do that:
/* The code you had for on hover */
.flip3d:hover >.front{
transform:perspective(600px)rotateY(-180deg);
}
.flip3d:hover >.back{
transform:perspective(600px)rotateY(0deg);
}
/* An example of what you can change it to */
.click-class-front {
transform:perspective(600px)rotateY(-180deg);
}
.click-class-front {
transform:perspective(600px)rotateY(0deg);
}
Then in your javascript/jquery code, you can do something like this:
$('.flip3d').click(function(){
if($(this).children('.front')) {
$(this).children('.front').toggleClass('click-class-front');
}
if($(this).children('.back')) {
$(this).children('.back').toggleClass('click-class-back');
}
});
When you click on the div with class front or back, it will check which one was clicked based on the class that is applied to them. It will then toggle(add or remove depending on previous state) the class, and the code in the CSS with that class will be applied.

On hover add / remove class - not always working

I'm implementing some animation by adding and removing classes to an element on mouseover and mouseout. I'm using this method as I found using CSS alone was not reliable; the animation would not complete if the mouse exited the element before the animation finished.
So I have the following code:
<div class="one flip-container">
<div class="flipper">
<div class="front">
<!-- front content -->
</div>
<div class="back">
<!-- back content -->
</div>
</div>
</div>
<script>
jQuery(".flip-container").hover(function () {
jQuery(this).addClass("hover");
},function () {
jQuery(this).delay(2000).queue(function(){
jQuery(this).removeClass("hover");
});
});
</script>
<style>
.flip-container.hover .flipper {
transform: rotateY(180deg);
}
.flipper {
transition: 0.6s;
transform-style: preserve-3d;
position: relative;
}
</style>
This works but sometimes the class 'hover' is not removed, it stays, leaving the element in its animated state. Any idea how to make this more reliable?

Try using mouseenter and then set a timeout function to remove the class that way you wont be adding and removing classes except once each time the mouse enters the area. Also you may want to check to see if the area already has the class to avoid the function from being executed too many times like so:
jQuery(".flip-container").mouseenter(function () {
var el = jQuery(this);
if(!el.hasClass("hover")){
el.addClass("hover");
setTimeout(function(){
el.removeClass("hover");
}, 2000);
}
});
Here is a working fiddle Fiddle Demo

Transition both ways between text elements

I have two paragraphs (lets say with id "p1" and "p2")
I would like to transition from one to another when a link is clicked, and vice versa when a different link is clicked. They are located on the same page but only one is displayed at a time (using javascript to hide one then display the other when the link is clicked).
Both paragraphs have "hidden page" as their classes.
Would the css resemble something like this?
.hidden {
opacity: 0;
display: none;
transition: opacity 1s linear;
}
.page {
transition: opacity 1s linear;
opacity: 1;
}
I know it's not that but would it be something similar?
EDIT:
Link to the gist of the css, js, and html files
https://gist.github.com/EricHanLiu/a4b09862f2d25b6c6e5f
edited out some things like name phone# email etc, but the main focus of is on the two paragraphs in the middle

If you are trying to fade in one paragraph when clicking on a link and faded the other one out if it is visible then you can do something like the following:
Live Preview
HTML:
<a id="first" href="#p1">1</a> <a id="second" href="#p2">2</a>
<div class="fadeIn">
<p id="p1" class="hidden">I am the first paragraph.</p>
</div>
<div class="fadeIn">
<p id="p2" class="hidden">I am the second paragraph.</p>
</div>
CSS:
.hidden {
opacity: 0;
}
/*fade in transition css below*/
.fadeIn p {
-webkit-transition: opacity 2.0s ease-in;
-moz-transition: opacity 2.0s ease-in;
-o-transition: opacity 2.0s ease-in;
}
.fadeIn p.clicked {
opacity: 1;
}
JavaScript:
//helper function to select the element by id
function $(id){
return document.getElementById(id);
}
//on click event for first
$("first").addEventListener("click",function(event){
//prevent page refresh or navigation
event.preventDefault();
$("p1").classList.add("clicked");
$("p2").classList.remove("clicked")
});
//on click event for second
$("second").addEventListener("click",function(event){
//prevent page refresh or navigation
event.preventDefault();
$("p1").classList.remove("clicked");
$("p2").classList.add("clicked");
});

As you said, you need two links to trigger the two paragraphs, respectively.
Here's my simple solution to your problem. I am not that sure that this is what you are looking for. But hopefully this helps!
<div>
<p class="show" id="p1">Paragraph 1</p>
<p class="hidden" id="p2">Paragraph 2</p>
Show Paragraph 1
Show Paragraph 2
</div>
<script type="text/javascript">
var sb1 = document.getElementById('sb1');
var sb2 = document.getElementById('sb2');
var p1 = document.getElementById('p1');
var p2 = document.getElementById('p2');
sb1.addEventListener('click', function() {
p1.classList.remove('hidden');
p1.classList.add('show');
p2.classList.remove('show');
p2.classList.add('hidden');
});
sb2.addEventListener('click', function() {
p1.classList.remove('show');
p1.classList.add('hidden');
p2.classList.remove('hidden');
p2.classList.add('show');
});
</script>
In the script above, I just switched the respective classes on the two paragraphs.
There a lot of solution to this, you can use jQuery to simplify this solution.

Create fade-out and slide-in animation for HTML content

I am trying to get an animation effect where current content fades out, and is then replaced by content sliding in from the right side of the screen. My current effort:
http://jsfiddle.net/LKazq/3/
<p>header</p>
<div id="wrapper">
<div style="height: 400px; background-color: red;">
<p>Here is some text!</p>
<button id="next">And a button!</button>
</div>
</div>
<p>footer</p>
$('#next').click(function () {
var current = $('#wrapper :first-child');
var next = $('<div>').css("height", "400px").css("background-color", "blue");
next.hide();
current.fadeOut(800, function () {
current.remove();
$('#wrapper').prepend(next);
next.show("slide", { direction: "right" }, 800);
});
});
Two problems:
The removed element is still taking up space; notice how the footer gets pushed down.
Is there anyway to suppress the horizontal scroll bar?
Any tips on better ways to do this are appreciated. Thanks!

The reason for the vertical scroll back is because of an additional UI wrapper that jQuery UI puts in place.
You can do this with regular jQuery and it should be just fine:
$('#next').on('click',function(){
var wrapper = $('#wrapper'),
current = wrapper.children().first(),
next = $('<div>').css({
height:400,
backgroundColor:'blue',
marginLeft:'100%',
display:'none'
});
current.fadeOut(800, function () {
$(this).remove();
wrapper.prepend(next);
next.show().animate({marginLeft:0},800);
});
});
Updated jsFiddle.
That's the quick-fix way to do it. An additional step is to externalize your CSS into classes (which you really, really should do instead of inline styles) to make things a bit cleaner:
HTML:
<p>header</p>
<div id="wrapper">
<div class="first">
<p>Here is some text!</p>
<button id="next">And a button!</button>
</div>
</div>
<p>footer</p>
CSS:
wrapper {
overflow:auto;
overflow-x:hidden;
}
.first {
height:400px;
background-color:red;
}
.second {
height:400px;
background-color:blue;
}
Better jQuery:
$('#next').on('click',function(){
var wrapper = $('#wrapper'),
current = wrapper.children().first(),
next = $('<div>').addClass('second').css({
marginLeft:'100%',
display:'none'
});
current.fadeOut(800, function () {
$(this).remove();
wrapper.prepend(next);
next.show().animate({marginLeft:0},800,function(){
$(this).removeAttr('style');
});
});
});
Here is a second jsFiddle for that.
And finally the best (although not ancient-browser compliant) way to do it, by maximizing CSS.
CSS:
#wrapper {
overflow:auto;
overflow-x:hidden;
}
.first {
height:400px;
background-color:red;
}
.second {
height:400px;
background-color:blue;
margin-left:0;
-webkit-transition:margin-left 800ms;
-moz-transition:margin-left 800ms;
-o-transition:margin-left 800ms;
transition:margin-left 800ms;
}
.secondPushed {
margin-left:100%;
}
Smaller jQuery:
$('#next').on('click',function(){
var wrapper = $('#wrapper'),
current = wrapper.children().first(),
next = $('<div>').addClass('second secondPushed').hide();
current.fadeOut(800, function () {
$(this).remove();
wrapper.prepend(next);
next.show().removeClass('secondPushed');
});
});
This is the best from an overhead perspective, and its the way to do it in the modern web world, but it doesn't work on IE9 and below.
Here's a jsFiddle for that one.
