keep moving an element up and down while mouse button is pressed

Everything works here but I need to keep moving act up and down while mouse button is pressed, without repeated clicks.
Any help?
$('button').on('click', function(){
let a = $('.act');
a.insertBefore(a.prev());
});
$('button').on('contextmenu', function(e){
e.preventDefault();
let a = $('.act');
a.insertAfter(a.next());
});
.act{background:gold;}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div>
<div class='title act'>LOREM</div>
<div class='title'>IPSUM</div>
<div class='title'>DOLOR</div>
<div class='title'>SIT</div>
<div class='title'>AMET</div>
</div>
<br>
<button>CLICK</button>

Instead of the click and contextmenu events you'll have to use mouse events, here is an example:
let intervalId;
const a = $('.act');
$('button').on('mousedown', function(event) {
function fn () {
if (event.button == 0) {
a.insertBefore(a.prev());
} else if (event.button == 2) {
a.insertAfter(a.next());
}
return fn;
};
intervalId = setInterval(fn(), 500);
});
$(document).on('mouseup', function(event) {
clearInterval(intervalId);
});
$('button').on('contextmenu', function(event) {
event.preventDefault();
});
.act {
background: gold;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div>
<div class='title act'>LOREM</div>
<div class='title'>IPSUM</div>
<div class='title'>DOLOR</div>
<div class='title'>SIT</div>
<div class='title'>AMET</div>
</div>
<br>
<button>CLICK</button>
In this example, I'm using an interval to move the element every 500 milliseconds while the mouse pointer is down, I'm also preventing the contextmenu event so that the context menu will not consume the mouseup event itself.

I've made a fiddle to illustrate:
https://jsfiddle.net/10cgxohk/
html:
<p class="">x</p>
css:
.move {
animation: MoveUpDown 1s linear infinite;
position: relative;
left: 0;
bottom: 0;
}
#keyframes MoveUpDown {
0%, 100% {
bottom: 0;
}
50% {
bottom: 15px;
}
}
javascript:
$('body').on('mousedown', function() {
$('p').addClass('move');
$('body').on('mouseup', function() {
$('p').removeClass('move');
$('body').off('mouseup');
console.log('here');
})
});
This is really rough and creates an issue if you have other 'mouseup' callbacks on the body, but if that's not a worry for you then it should work. The javascript is adding a class to the element, and the class is animated in css

Click outside of element to hide element

My code does this: when element .pencil is clicked on, it toggles the hidden element .pencilpanel. When clicked outside of this .test element (there are two .test elements), then this .pencilpanel should hide.
However, my problems are that:
1) When the second .test element is clicked on, the first .test element remains visible when it should be hidden. And,
2) When the first .pencil element is clicked on, and its corresponding .pencilpanel is also clicked on, it will hide .pencilpanel, when it's supposed to remain visible. Any element that is currently visible within .test, and if clicked on, should not be hidden, unless that clicked on element lies outside of the current .test element.
So I'm not getting why when a click is made on .pencilpanel, it hides it on this line if(!$(this).closest('.test').length && $('.pencilpanel').is(":visible")) {. And the fact that the first .pencilpanel remains visible when it should be hidden whenever another .pencil is clicked on. This is my code:
$(document).ready(function () {
$('.pencil').on('click', function (event) {
event.stopPropagation();
$(this).parent(".btsdiv").next(".fcmdiv").children(".pencilpanel").toggleClass("displayblock");
});
});
$(document).ready(function () {
$(document).click(function () {
if (!$(this).closest('.test').length && $('.pencilpanel').is(":visible")) {
$('.pencilpanel').removeClass("displayblock");
}
});
});
.pencilpanel {
display: none;
}
.displayblock {
display: block;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="test">

You can use the document.activeElement to check before you close the panels. Please find the modified code.
$(document).ready(function() {
$('.pencil').on('click', function(event) {
event.stopPropagation();
closePanel();
$(this).closest(".test").find(".pencilpanel").toggleClass("displayblock");
});
$(document).on("click", function() {
if (document.activeElement.tagName != 'TEXTAREA')
closePanel();
});
});
function closePanel() {
$('.pencilpanel').removeClass("displayblock");
}
.pencilpanel {
display: none;
}
.displayblock {
display: block;
}

jQuery - progressivly showing div

I would like to show some divs, one by one, with a sliding effect from the left or right part of the screen. So far i'm stuck between this
<button id='animer'>animer</button>
<div class="left">from left</div>
<div class="right">from right</div>
<div class="left">from left</div>
<div class="right">from right</div>
<script>
$(function() {
$('.left, .right').hide();
$('#animer').click(function() {
$(".left").toggle("slide", {direction: "left"}, 500);
$(".right").toggle("slide", {direction: "right"}, 500);
});
});
</script>
and that
<button id='animer'>animer</button>
<div class="all">from left</div>
<div class="all">from right</div>
<div class="all">from left</div>
<div class="all">from right</div>
<script>
$(function() {
$('.all').hide();
$('#animer').click(function() {
$('.all').first().show('slow', function showNextOne() {
$(this).next('.all').show('slow', showNextOne);
});
});
});
</script>
But i need this to work no matter the divs order, because the "left" or "right" items will come randomly.
Help will be much appreciated as i am not as competent as i wished in jQuery. ^^

The following uses the all variable to keep a list of all of the divs. When the button is clicked, the slideNext() function is executed, checking the class of the current item to decide on toggle direction, and specifying slideNext (itself) as the function to run when the toggle is complete.
$(function() {
var all = $('.left, .right').hide();
$('#animer').click(function() {
var i = 0;
(function slideNext() {
if (i < all.length) {
var current = all.eq(i);
current.toggle("slide", {
direction: current.hasClass("left") ? "left" : "right"
}, 500, slideNext);
}
i++;
})();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="https://code.jquery.com/ui/1.9.2/jquery-ui.min.js"></script>
<button id='animer'>animer</button>
<div class="left">from left</div>
<div class="right">from right</div>
<div class="left">from left</div>
<div class="right">from right</div>

You can use index from each() loop for delay and set direction based on condition if current div hasClass() left or not.
$(function() {
$('div').hide();
$('#animer').click(function() {
$('div').each(function(i) {
let dir = $(this).hasClass('left') ? 'left' : 'right';
$(this).delay(i * 1000).toggle('slide', {direction: dir})
})
});
});

Using array to change colours

hi I'm trying to use an array to change colors. I want to Make a function called ChangeColor(num) with an argument for numbers and Use the function to change the color of the box so when the button is clicked on, it calls on the function and sends the correct number so that "box.style.backgroundColor = arrName[num];" Heres what i got so far.
<!DOCTYPE html>
<html>
<head>
<style>
#box {
width:200px;
height:200px;
background-color:black;
}
</style>
</head>
<body>
<div id="group">
<button id="blue">Blue</button>
<button id="red">Red</button>
<button id="green">Green</button>
</div>
<div id="box"></div>
<script type="text/javascript">
var colors = ["blue","red","green"];
var blue = document.getElementById("blue");
var red = document.getElementById("red");
var green = document.getElementById("green");
var box = document.getElementById("box");
var numclicks = 0;
blue.addEventListener("click", function() {
if(numclicks == 0) {
box.style.backgroundColor = colors[0];
}
});
red.addEventListener("click", function() {
if(numclicks == 0) {
box.style.backgroundColor = colors[1];
}
});
green.addEventListener("click", function() {
if(numclicks == 0) {
box.style.backgroundColor = colors[2];
}
});
</script>
</body>
</html>

You can simply attach an event listener to the buttons within #group and set the background-color of the #box the id of the clicked button:
var box = document.querySelector('#box');
document
.querySelectorAll('#group button')
.forEach(function (el) {
el.addEventListener('click', function () {
box.style.backgroundColor = el.id;
});
});
#box {
width:200px;
height:200px;
background-color:black;
}
<div id="group">
<button id="blue">Blue</button>
<button id="red">Red</button>
<button id="green">Green</button>
</div>
<div id="box"></div>

standard function
const colors = ["blue","red","green"];
const defaultColor = "white"; // if you want for kill errors
function changeColor(num){
document.querySelector("#box").style.backgroundColor = colors[num]||defaultColor
}
then you can added onclick events to buttons like this
<div id="group">
<button onclick="changeColor(0)" id="blue">Blue</button>
<button onclick="changeColor(1)" id="red">Red</button>
<button onclick="changeColor(0)" id="green">Green</button>
</div>
or with attributes like (but keep buttons elements depend to same order of array colors names)
html
<div id="group">
<button number="0" id="blue">Blue</button>
<button number="1" id="red">Red</button>
<button number="2" id="green">Green</button>
</div>
javascript
document.querySelectorAll("#group button").forEach((button)=>{
button.addEventListener('click', function () {
changeColor(button.getAttr("number"));
});
});

The other solutions use practices that are currently considered better. Here is a solution that includes the unnecessary array.
function changeColor(num) {
var colors = ['blue', 'red', 'green'];
document.getElementById('box').style.backgroundColor = colors[num];
}
#box {
width: 200px;
height: 200px;
background-color: black;
}
<div id="group">
<button id="blue" onclick="changeColor(0)">Blue</button>
<button id="red" onclick="changeColor(1)">Red</button>
<button id="green" onclick="changeColor(2)">Green</button>
</div>
<div id="box"></div>

how to check if it was the last element

how can I check if it was the last div? If it was I need to remove all classes "ready"
html:
<div class="green"></div>
<div class="orange"></div>
<div class="red"></div>
<div class="green"></div>
<div class="orange"></div>
js:
$(function() {
setInterval(showBlock, 1000);
function showBlock() {
var x = $("div:first").addClass("ready");
var c = $("div");
$(".ready").css("display", "block");
if (c.hasClass("ready")) {
$(".ready:last").next().addClass("ready");
}
}
})
;

Looking at your code what I understand is you want display one div after each second. For that I'll suggest following approach.
First add hidden class to all divs and then remove it from first hidden div at each second.
$(function() {
$('div').addClass('hidden');
var i = setInterval(showBlock, 1000);
function showBlock() {
var x = $("div.hidden:first").removeClass("hidden");
if($("div.hidden").length == 0) {
clearInterval(i);
}
}
});
.hidden {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="green">Green</div>
<div class="orange">Orange</div>
<div class="red">Red</div>
<div class="green">Green</div>
<div class="orange">Orange</div>

As far as I understand your problem, following solution must work in your case:
$(function() {
setInterval(showBlock, 1000);
function showBlock() {
var ready_divs = $("div.ready").length;
var total_divs = $("div").length;
if(ready_divs!=total_divs){
if(ready_divs==0){
$("div:first").addClass('ready');
}else{
$("div.ready:last").next('div').addClass('ready');
}
}else{
$("div").removeClass('ready')
}
}
});
div{
width: 20px;
height: 20px;
border:1px solid red;
}
div.ready{
border:3px solid blue;
}
