smooth-scrollbar.js - Disable scroll when fullscreen menu open, activate when menu closed

As per the title, I am using smooth-scrollbar.js along with this fullscreen menu. Currently when you click the button to open the menu, you can still scroll the page, im trying to disable scrolling when the menu is opened and then re-enable scrolling when the menu is closed. I have been reading on forums online and someone suggested using "scrollbar.destroy()" but I have not been able to accomplish what i need using this, maybe i used it incorrectly.
If anyone has any suggestions on how to accomplish this, that would be great!

just added some css trick in this case, added burgerOpen this class to body element
body.burgerOpen {
overflow: hidden;
}
Try below demo
const burger = document.querySelector('#burger')
const tl = gsap.timeline()
tl.to('.menu-link', {
translateY: '100%',
duration: 0.5,
})
tl.to('.menu-overlay', {

})
burger.addEventListener('click', () => {
tl.reversed(!tl.reversed());
$('body').toggleClass('burgerOpen');
})

import Scrollbar, { ScrollbarPlugin } from 'smooth-scrollbar';
class ModalPlugin extends ScrollbarPlugin {
static pluginName = 'modal';
static defaultOptions = {
open: false,
};
transformDelta(delta) {
return this.options.open ? { x: 0, y: 0 } : delta;
}
}
Scrollbar.use(ModalPlugin);
const options = {
delegateTo: document,
damping: 0.05,
continuousScrolling: false,
};
const wrapper = document.querySelector('.wrapper');
const scrollbar = Scrollbar.init(wrapper, options);
And toggle the scrollbar state where you need it:
scrollbar.updatePluginOptions('modal', { open: false }); // true, false

HTML + CSS | Issue with main content not overlapping with nav bar

I have a main content area, which I want to be centered in the page both vertically and horizontally.
I added a css nav bar, but now the page has scroll bars both vertically and horizontally, and the main div is no longer centered. It appears to be moved to the right and down by the nav bar. I'm trying to have the main sit centrally, and then the nav "overlay" everything else so it doesn't affect the main div's positioning.
I think it has something to do with z-index but changing those values doesn't seem to achieve anything. Could anyone direct me to a resource to learn about the right way to fix this?
Thank you.
(It's all pretty scrappy as I'm just beginning to learn!)

you can set the body padding & margin to 0,
body {
z-index: 0;
background-color: black;
width: 100vw;
height: 100vh;
padding: 0;
margin: 0
}
this solves your current problem, but may get the same problem again in other divs, what I usually do is to set all paddings and margins to zero. like this
* {
margin: 0;
padding: 0;
box-sizing: border-box
}
You need to learn how to debug your css: https://developer.mozilla.org/en-US/docs/Learn/CSS/Building_blocks/Debugging_CSS

The problem is not with your navbar but with the body of your webpage. Just add margin: 0 and padding: 0 to your body and the scrollbars should disappear.
Check and run the following Code Snippet or this CodePen for a practical example of your webpage with the margin: 0 property added:
const textElement = document.getElementById('text')
const optionButtonsElement = document.getElementById('option-buttons')
let state = {}
function startGame() {
state = {};
showTextNode(1);
}
function showTextNode(textNodeIndex) {
const textNode = textNodes.find(textNode => textNode.id === textNodeIndex);
textElement.innerText = textNode.text;
while(optionButtonsElement.firstChild) {
optionButtonsElement.removeChild(optionButtonsElement.firstChild);
}
document.getElementById('image').style.display = "block"
textNode.imageLink ? document.getElementById('image').style.backgroundImage = `url(${textNode.imageLink})` : document.getElementById('image').style.display = "none";
textNode.options.forEach(option => {
if(showOption(option)) {
const button = document.createElement('button');
button.innerText = option.text;
button.classList.add('btn')
button.addEventListener('click', () => selectOption(option));
optionButtonsElement.appendChild(button);
}
})
}
function showOption(){
return true;
}
function selectOption(option) {
const nextTextNodeId = option.nextText;

showTextNode(nextTextNodeId)

According to the accepted answer on this other SO thread, the reason why margin and padding are not 0 by default is because browsers have different default style-sheets.

Change your css body attributes to the following:
body {
z-index: 0;
background-color: black;

By setting the padding and margin to 0px for the body, you'll get rid of the scrollbars both vertically and horizontally :)

Add/Remove class to get a menu to display

I started programming the mobile version of my nav menu earlier. I had to rework my #serviceNav to get it to work in a mobile setting. When doing this I changed my javascript from this:
/*$('#serviceClick').click( function () {
$('#serviceNav').addClass('activeSol');
});*/
$('[data-pop-close]').on('click', function(e) {
//var targeted_pop = $(this).attr('data-pop-close');
$('#serviceNav').removeClass('active');
$('body').css('overflow', 'auto');
e.preventDefault();
});
To this:
$('#serviceClick').click(function() {
var relative = $(this);
if (!relative.hasClass('activeSol')) {
$('.activeSol').removeClass('activeSol').next('#serviceNav').slideUp(500);
relative.addClass('activeSol').next('#serviceNav').slideDown();
//$('.infoTitles:before').addClass('opened');
} else {
relative.removeClass('activeSol').next('#serviceNav').slideUp(500);
}
return false;
});
The issue that I am having now that I previously didn't with my javascript code is that now my desktop media query version of my #serviceNav is not displaying, however it does display and function in the mobile setting. The trigger for this menu is the menu item called "Solutions". You can see that in a media query over 640px that nothing happens, but 640px or less it applies the fadeDown function.
Does anyone see why this is not working for the larger version media query?
Here is a jsfiddle
Full code:
$('#mobile-button').on('click', function () {
$('#nav-pop').addClass('active');
$('html').addClass('is-navOpen');
});
/*$('#serviceClick').click( function () {
$('#serviceNav').addClass('activeSol');
});*/
$('#serviceClick').click(function() {
var relative = $(this);
if (!relative.hasClass('activeSol')) {
$('.activeSol').removeClass('activeSol').next('#serviceNav').slideUp(500);
relative.addClass('activeSol').next('#serviceNav').slideDown();
} else {
relative.removeClass('activeSol').next('#serviceNav').slideUp(500);
}
return false;
});

There is a lot going on here and frankly, it's hard to decipher but I think "Nothing happens" is relative. When inspecting the element in dev console you can see the Javascript styling is being added appropriately. So something is happening, it's simply happening off screen because you've told it to. I think the culprit here, is the >640px positioning of your #serviceNav element is maintained at top: -40vh; That's a lot. When removing this value the button displays as follows:
Note: you will have to change some other things around as this displays it on page load. But you get the idea

Click function never reading else statement to remove class

I have been stuck on a sliding down menu, but have made some headway with it. I had to modify a lot to make it work for both desktop and mobile viewports. The only thing I am stuck on now is getting the menu to close in a < 640px viewport.
In my snippet and jsfiddle below there is a lot of code, but the only code that really matters to this question is the javascript below:
$('#serviceClick').click( function () {
var relative = $(this);
if (!relative.hasClass('activeSol')) {
$('#serviceNav').removeClass('activeSol');
$('#serviceNav').addClass('activeSol').slideDown();
} else {
$('#serviceNav').removeClass('activeSol').slideUp(500);
}
return false;
});
Basically my else statement is now removing the class 'activeSol` and then sliding up the selection.
In the mobile viewport, after clicking on "Solutions" the menu expands, but when you click on "Solutions" again, nothing happens.
It seems as if the variable relative is never reading as the class appended to it, making the click function run else. I did a simple console.log and the else never runs. I tried changing the click function to a change, but then the menu never triggers.
Does anyone see what is causing my else statement to not removeClass from serviceNav and slideUp?
JSfiddle link to see in mobile viewport.
$('#serviceClick').click( function () {
var relative = $(this);
if (!relative.hasClass('activeSol')) {
$('#serviceNav').removeClass('activeSol');
$('#serviceNav').addClass('activeSol').slideDown();
} else {
$('#serviceNav').removeClass('activeSol').slideUp(500);
}
return false;
});
$('[data-pop-close]').on('click', function(e) {
//var targeted_pop = $(this).attr('data-pop-close');
$('#serviceNav').removeClass('activeSol');
$('body').css('overflow', 'auto');
e.preventDefault();
});

var relative = $(this);
Is picking the serviceClick list item (li) and then you are checking
if (!relative.hasClass('activeSol')) {
but you never added the class to the li, instead you added it to the div #serviceNav.
I think changing
if (!relative.hasClass('activeSol')) {
to
if (!$('#serviceNav').hasClass('activeSol')) {
should work.

Your shouldn't check for $("#serviceClick") for class activeSol, should check on $("#serviceNav") instead.
if (!$('#serviceNav').hasClass('activeSol')) {
$('#serviceNav').removeClass('activeSol');
$('#serviceNav').addClass('activeSol').slideDown();
} else {
$('#serviceNav').removeClass('activeSol').slideUp(500);
}

relative doesn't have the class 'activeSol' and will never have it, in order to have it toggle the visibility of your menu, you should add and remove classes to it, like this:
$('#serviceClick').click( function () {
var relative = $(this);
if (!relative.hasClass('opened')) { // if it's not opened
relative.addClass('opened'); // open it
$('#serviceNav').removeClass('activeSol');
$('#serviceNav').addClass('activeSol').slideDown();
} else { // if it's opened
relative.removeClass('opened'); // close it
$('#serviceNav').removeClass('activeSol').slideUp(500);
}
return false;
});

Javascript button to open a modal; button doesn't work when in a list

Basically, I want to press a button (matched to a person) that brings up a pop-up (right now using a modal) of an of another page which will vary based on which person it is. I am using a basic template from the w3school and I can get one button working, but when I try and add a button into the list to match a person, the modal does not open. Obviously for each button to be assigned to one person they will need to have their own element id, but why cant I get even one button to work?
Its the "show on map" button in the snippet below.
The top most "show on map" button works in the sense that it brings up the modal, but the same buttons in the list do nothing.
Thank you in advance.
// Get the modal
var modal = document.getElementById('myModal');
// Get the button that opens the modal
var btn = document.getElementById("myBtn");
// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];
// When the user clicks the button, open the modal
btn.onclick = function() {
modal.style.display = "block";
}
// When the user clicks on <span> (x), close the modal
span.onclick = function() {
modal.style.display = "none";
}
// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
if (event.target == modal) {
modal.style.display = "none";
}
}

Id's should always be unique.
The id global attribute defines a unique identifier (ID) which must be
unique in the whole document. Its purpose is to identify the element
when linking (using a fragment identifier), scripting, or styling
(with CSS).
That is also the origin of your problem. document.getElementById("theid"); will return the first element (and also the only element expected to use this id). However you want to assign your onclick method to multiple buttons.
You should consider to use the name attribute instead. Then you can use document.getElementsByName("myBtn") in order to loop through all buttons and register your listener. The code below contains comments that should explain my changes.
// Get the modal
var modal = document.getElementById('myModal');
// Get all buttons that should opens the modal
var btns = document.getElementsByName("myBtn");
// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];
// The iframe inside of the Modal
var modalIFrame = document.getElementById("modal-iframe");
// When the user clicks the button, open the modal
for(var i = 0; i < btns.length; i++) {
(function(i) {
var btn = btns[i];
// you should use addEventListener("click", function() {}); here
btn.onclick = function() {
// this will set the iframe url every time you press a button and add the "id" of the button that was pressed as a parameter. "id" is just the current index of the for loop for now.
modalIFrame.setAttribute("src", "map.html?id=" + i);
modal.style.display = "block";
}
})(i);
}
// When the user clicks on <span> (x), close the modal
span.onclick = function() {
modal.style.display = "none";
}
// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
if (event.target == modal) {
modal.style.display = "none";
}

In HTML the id attribute is unique. As such, you are only ever binding to the first button with the id of myBtn (I go and get the element by id and I only get one because that's what's expected).
You will need to make the IDs unique and bind each one's click event, that or apply a class, get an array of buttons by class, and bind each button in the array.
If you had a class named showModalButton set on each button you could get the references with:
var elements = document.getElementsByClassName('showModalButton');
and then iterate over the elements and bind:
for(var i = 0; i < elements.length; ++i) {
elements[i].onclick = function() {
modal.style.display = "block";
}
}
