I have a function which must be executed immediately then in an eventListener.
Here is how I run both:
function mediaBodyClass() {
var body = document.body;
if (window.innerWidth >= 992) {
body.classList.add('desktop');
body.classList.remove('mobile');
} else {
body.classList.add('mobile');
body.classList.remove('desktop');
}
};
mediaBodyClass(); // Now
// In the listener
window.addEventListener('resize', function() {
mediaBodyClass();
});
What is the best practice?

Whilst what you are doing is fine - you might find the matchMedia api useful - basically its a javascript version of a media query in which you can attach functions to given viewport widths and also listen for changes to the viewport size.
Here is a link to a useful article.https://css-tricks.com/working-with-javascript-media-queries/
const mediaQuery = window.matchMedia('(min-width: 992px)')
function handleViewportSizeChange(e) {
var body = document.body;
if (e.matches) {
body.classList.add('desktop');
body.classList.remove('mobile');
}else {
body.classList.add('mobile');
body.classList.remove('desktop');
}
}
// Register event listener
mediaQuery.addListener(handleViewportSizeChange)
// Initial check
handleViewportSizeChange(mediaQuery)

You can use a media query to apply styles to the body when the screen width is smaller than a certain limit, instead of using JavaScript:
body{
/* .desktop styles go here */
}
#media only screen and (max-width: 992px) {
body {
/* .mobile styles go here */
}
}

The below Javascript (triggering the pagination background color of an element, when another element scrolls into view) doesn't work in Internet Explorer but in all other browsers. Does anyone have any idea why?
The code basis is also available in my pen: https://codepen.io/headstarterz/pen/PMdZdV/
<script>
function inViewport(element) {
// Get the elements position relative to the viewport
var bb = element.getBoundingClientRect();
// Check if the element is outside the viewport
// Then invert the returned value because you want to know the opposite
return !(bb.top > innerHeight || bb.bottom < 0);
}
var project1 = document.querySelector(".project-trigger1");
var project2 = document.querySelector(".project-trigger2");
var project3 = document.querySelector(".project-trigger3");
var pagination1 = document.querySelector(".bullet1");
var pagination2 = document.querySelector(".bullet2");
var pagination3 = document.querySelector(".bullet3");
// Listen for the scroll event
document.addEventListener("scroll", event => {
// Check the viewport status
if (inViewport(project1)) {
pagination1.style.background = "#e3e3e3";
} else {
pagination1.style.background = "transparent";
}
});
document.addEventListener("scroll", event => {
// Check the viewport status
if (inViewport(project2)) {
pagination2.style.background = "#e3e3e3";
} else {
pagination2.style.background = "transparent";
}
});
document.addEventListener("scroll", event => {
// Check the viewport status
if (inViewport(project3)) {
pagination3.style.background = "#e3e3e3";
} else {
pagination3.style.background = "transparent";
}
});
</script>
Script works in Chrome, Safari, Firefox, Edge
Script doesn't work in Internet Explorer 11

It is probably two reasons:
Firstly your closing <script> tag is spelled wrong (<skript>).
Also, you're using 'fat arrow functions', which is a feature of ES6. I would look into something like Babel to transpile your code to a I.E. friendly syntax

Button in wrong place in meteor app [closed]

I made a little app and my button shows only on one place. It's all working but on wrong place. See pictures. I'll leave my GitHub repo link. Sorry most of stuff is on Cyrillic but code is, of course, on English Latin.
Here is a video of my problem (22 sec)
Thank you for your help.

You're problem is with id. HTML ids are unique, so when you do document.getElementById('skocko'), you only get back the first element with that id.
Instead, give the button a class of skocko, and access it like this:
Template.myTemplate.events({
"click .glasaj":function(event, template){
template.$(".skocko").toggle();
}
}
This will select the element with class skocko in the current template.

check div positioning How to position one element relative to another with jQuery? so its position can be relative to button clicked, or assign unique skocko id for every skocko..

Do something like this in your script glasaj.js
if (Meteor.isClient) {
Template.glasajDugme.events({
'click .glasaj': function(){
var g = Meteor.user().profile.неискоришћениГласови;
if (g < 1) {
var pos = $(this).position();
// .outerWidth() takes into account border and padding.
var width = $(this).outerWidth();
//show the menu directly over the placeholder
$("#skocko").css({
position: "absolute",
top: pos.top + "px",
left: (pos.left + width) + "px"
}).show();
document.getElementById('skocko').style.display = "inline-flex";
// return "disabled" ;
}
else {
Predlozi.update(this._id, {$inc: {Број_Гласова: 1}}
);
Meteor.users.update(Meteor.userId(), {$inc: {"profile.неискоришћениГласови": -1}}
);
};
}
});
sakrijskocka = function(){
document.getElementById('skocko').style.display = "none";
};
};

I've used JavaScript just for this purpose but it only works when I refresh the browser ...
<script>
var scroll = window.scrollY ;
var header = document.getElementById("header");
function my(){
if (scroll >= header.scrollHeight) {
header.style.height = 100 +"px";
} else {header.style.height = 250 + "px";}
}
my();
</script>

You would need to add a scroll event listener :
var scroll, header = document.getElementById("header");
function my() {
scroll = window.scrollY;
if (scroll >= header.clientHeight) header.style.height = 100 + "px";
else header.style.height = 250 + "px";
}
window.addEventListener('scroll', my, false);
window.addEventListener('load', my, false);
Also added a listener that will respond to when the page has fully loaded, this will make sure the function executes when the user lands on the page and a scroll position was cached before...

If height more than 100px, change position [closed]

I have this code:
$(document).ready(function () {
if ($('.pi-img').height() > 100) {
$(this).css('top' , '30%');
console.log('yeah');
}
});
But it doesn't work.

You need to use .each() to loop through the .pi-img elements:
$(document).ready(function () {
$('.pi-img').each(function() {
if ($(this).height() > 100) {
$(this).css('top' , '30%');
console.log('yeah');
}
});
});
