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().

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");
}
});
});
<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>

Is ng-option animation aware in angulajs 1.4?

I'm trying to use ngAnimate(v1.4) for ng-option but I couldn't find any animate event for it in angularjs documentation. Does anyone know if ng-option directive animation aware? Can anyone provide a link for reference or an example?
I'm trying to add animation to select2 dropdown using angularjs ngAnimate. But not able to do so. See the fiddle https://jsfiddle.net/ashishU/o6ojj9xs/
I'm not sure which ngAnimate event to add the animation to. It doesn't seem to work.
Below is my code:
HTML
<div ng-app="testApp">
<div ng-controller="testCtrl">
<select class="dd1" ng-model="dropDown1" ng-options="value for value in dropDownValue1">
<option value="">{{dropDownName1}}</option>
</select>
JAVASCRIPT
angular.module("testApp", ["ngAnimate"]).controller("testCtrl", function($scope) {
$scope.dropDownName1 = "animateDD1";
$scope.dropDownValue1 = ['This', 'IS', 'Animation', 'For', 'DD1'];
$(".dd1").select2();
});
CSS
#keyframes openDD {
from {
opacity: 0;
}
to {
opacity: 1;
}
}
#keyframes closeDD {
from {
opacity: 1;
}
to {
opacity: 0;
}
}
.dd2.ng-enter {
animation: openDD 2s;
}
.dd2.ng-leave {
animation: closeDD 1s;
}

I can't get my animation to work on load of my website using jquery

So the problem I am having is that I can't seem to get my jQuery Function to add a class to start my animation? I have tried a lot of different ways to get it to work, none of them are working!
jQuery
$(document).ready(function(){
window.onload = function render(){
$('.title .sub-title').addClass('render');
}
});
CSS
.render {
animation-name: render;
animation-duration: 2s;
animation-timing-function: ease-in-out;
}
#keyframes render {
0% { transform: translateX(-800px); }
100% { transform: translateX( 0px ); }
}
HTML
<div class="site-header-title-wrapper">
<h1 class="title">Template 1</h1><!--Need To add animation
<h4 class="sub-title">- Here is a Template Slogan -</h4><!--Need To add animation to-->
</div>
Please can someone help?
It would be very beneficial!

Try the following:
$(document).ready(function(){
$('.title, .sub-title').addClass('render');
});
The code in your example is targeting a .sub-title element nested within a .title element. Including a comma in your CSS selector should fix this.

Your .sub-title class is commented out. Try this:
<div class="site-header-title-wrapper">
<h1 class="title">Template 1</h1>
<h4 class="sub-title">- Here is a Template Slogan -</h4>
</div>

angular ngShow with animate.css

I want to animate the showing and hiding of an element using animate.css and angular.
I have read this SO question and the angular documentation for ngShow and ngAnimate but still cannot get it to work.
I have tried the following setup on plunker, but it doesn't work.
app.js
var app = angular.module('plunker', ['ngAnimate']);
app.controller('MainCtrl', function($scope) {
$scope.show = true;
});
index.html
<body ng-controller="MainCtrl">
<p>Show: {{show}}</p>
<div class="show" ng-click="show = !show" ng-show="show === true">Show is true</div>
<div class="hide" ng-click="show = !show" ng-show="show === false">Show is false</div>
</body>
style.css
.show.ng-hide-add {
animation: fadeOut 5s linear;
}
When clicking on "show is true" (and therefor hiding it) I see it wait for 5 second before hiding, so there is something happening, but it doesn't fade out.
I can make it work if I add this to the css:
.show.ng-hide-add {
opacity: 1.0;
display: block !important;
transition: opacity 1s;
}
.show.ng-hide-add-active {
opacity: 0;
}
However, I don't want to do it this way. I want to use animate.css's keyframes (I think that's the correct term, my css lingo isn't brilliant) such as fadeIn, fadeOut etc..
plunker to show what I am seeing.
What am I doing wrong? How can I use animate.css's keyframe animations with angular's ngAnimate?

You have to use .ng-hide class, as it's the class that is assigned once the condition in ng-show is false, or in ng-hide is true.
According to that you can edit your code like this:
.show.ng-hide,
.hide.ng-hide{
opacity: 0;
transition: all linear 0.5s;
}
.show,
.hide{
transition: all linear 0.5s;
opacity:1;
}
<p>Show: {{show}}</p>
<div class="show" ng-click="show = !show" ng-show="show">Show</div>
<div class="hide" ng-click="show = !show" ng-hide="show">Hide</div>
-
EDIT:
In case you want to use the animate.css classes, for example .fadeIn and .fadeOut you have to assign the corresponding keyframes inside your css.
So you have to use the following CSS:
.show.ng-hide,
.hide.ng-hide{
animation-name:fadeOut;
animation-duration: .5s;
}
.show{
animation-name:fadeIn;
animation-duration: .5s;
}
IMPORTANT NOTE:
In order to make it work correctly in the plunker I have not used the 3.2.0 version suggested by the plunker external library finder, but I manually linked the 3.5.1 version adding the following code in the html
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/animate.css/3.5.1/animate.css" />

Working Plunker with full code

Change your code to this
<div ng-show="show">
<div class="show" ng-click="show = !show">Show</div>
</div>
<div ng-show="!show">
<div class="hide" ng-click="show = !show" >Hide</div>
</div>
.show.ng-hide{
opacity: 0;
transition: all linear 0.5s;
}
.show{
transition: all linear 0.5s;
opacity:1;
}

AngularJS can we trigger the move animation event manually

In the ng-repeat section there are animations event handler for enter, leave and move. But the move event is only triggered when we resort or filter the array used for ng-repeat. What if I only change the attribute values of my objects. Then no event is triggered at all. Is there a way to trigger the event manually after I have changed the object attribute?
Here is a fiddle: http://jsfiddle.net/U3pVM/15002/
Html:
<ul>
<li ng-repeat="d in data">
<div class="lala" style="width: {{d.a}}px">foo</div>
</li>
</ul>
JS:
function TodoCtrl($scope) {
$scope.data = [{a:100}, {a:120}];
// I would like to animate the value changes
$scope.change = function() {
$scope.data[0].a = 110;
$scope.data[1].a = 90;
}
}

your class definitions are wrong.
.lala,
.lala.ng-enter,
.lala.ng-move,
.lala.ng-leave {
background-color: grey;
-webkit-transition:all 1s linear;
-moz-transition:1s linear all;
-o-transition:1s linear all;
transition:all 1s linear;
}
See the working fiddle here.

just add transition to the main class
.lala{
transition:0.5s;
background-color:grey;
}
