Trying to run specific js script by pass button with specific id or class

I am trying to run this script with a specific id or class of buttons as on my website I have multiple control.
Now, these things run okay when I don't use any class or id in it, but as soon as I add anything specific, it won't. do have a look at the code and let me know how we can solve it.

As for check I have used class = classIneed which does not work but if change it to just button it will.

You're missing a dot in your selection, as jQuery doesn't know what you're looking for.
You should use $("#id") or $(".class"), # is for IDs of elements, while . is for classes.
If you write the syntax without any of those, if I'm not mistaken, you're then actually searching for tag names, i.e. $("div"), $("h1") etc.

Button disappears after several click

I really struggling with doing the same thing in infinite try.
I'm trying to add same functionality to similar element using Foreach on the parent element.
everything went well until I hit the buttons several times, it just disappear.
I think the problem is in the loop, I welcome any kink of comments.

I will appreciate any kind of help
thank you

I checked it out and found that the active_arr class the the one that is causing the problem, the buttons are not disappearing but just moving outside the boundary of the parent container which has a overflow: hidden; property. You are forgetting to remove the arctive_arr class from the opposite button do as follows and it will work
const containerDivs = document.querySelectorAll('.box.center');
containerDivs.forEach(containerDiv => {
const leftContainer = containerDiv.querySelector('.left_container');
const arrow = containerDiv.querySelector('.arr_container');
const cancel = containerDiv.querySelector('.cancel');
arrow.addEventListener("click", ({ target: arrow }) => {
arrow.classList.add("active_arr");
if (leftContainer.classList.contains("off")) {
leftContainer.classList.remove("off");
leftContainer.classList.add("active");
}
cancel.classList.remove("active_arr");
});
cancel.addEventListener("click", ({ target: cancel }) => {
cancel.classList.add("active_arr");
if (leftContainer.classList.contains("active")) {
leftContainer.classList.remove("active");
leftContainer.classList.add("off")
}
arrow.classList.remove("active_arr");
});
});
Tho there is still a padding issue I can see you can fix it on your own

You are adding "active_arr" but you never remove it.
Your css are hiding the buttons then:
.active_arr {
transform: translate(80%, 80%);
}

How to create a button in following style?

I want to create two button which will float next to each other and also when we click one of them it will change background-color to #474e5d and some shadow effect. I am very new to design please help me to do this.
Click here to see the button design

//js
const span2 = document.getElementById("span2")
const span1 = document.getElementById("span1")
span2.addEventListener("click",function ( ) {
const span3 = document.getElementById("span3")
span3.style.left="150px"
span3.innerHTML="Search by dictric"
span3.style.transition = "all 0.5s";
})
span1.addEventListener("click",function () {
const span3 = document.getElementById("span3")
span3.style.left="0px"
span3.innerHTML="Search by pin code"
span3.style.transition = "all 0.5s";
})
/* css */
.sld_btn{
display: flex;
width: 300px;
height: 40px;
border-radius: 25px;
position: relative;
background-color: rgb(102, 102, 102);
}
.sld_btn span{
width: 100%;
display: flex;
justify-content: center;

}
#span3{
border-radius: 25px;
position: absolute;
height: 100%;
width:150px ;
background-color: rgb(151, 151, 151);
box-shadow: 5px 5px 5px rgba(41, 41, 41, 0.5);

I think this is close to what you are looking for. I can explain individual parts if you want.
Click on Run Code Snippet to see it working.

scroll eventListener not working in javascript

window.addEventListener for scroll event is not working in my JS. I've tried several ways but still not working. I've used intersectionObserver in the JS also. Here is the JS code
const moveToAbout = () => {
document.getElementById('about').scrollIntoView(true)
}
const moveToWork = () => {
document.getElementById('work').scrollIntoView()
}
const moveToTop = () => {
document.getElementById('main-section').scrollIntoView(true)
}
const options = {
root: null,
threshold: 0,
rootMargin: "-150px"
}
const header = document.querySelector("header")
const sections = document.querySelectorAll(".section")
const mainSection = document.querySelector(".main-container")
const bttWrapper = document.getElementById('bttBtn-wrapper')
const veganImage = document.getElementById('vegan-store-image')
const navbar = document.getElementById('header')
veganImage.onclick = () => {
window.open("https://thoughtlessmind.github.io/Vegan-store")
}
const sectionOne = document.querySelector(".about-section");
// bttWrapper.style.display = 'none'
const mainObserver = new IntersectionObserver(function (entries, observer) {
entries.forEach(entry => {
if (entry.isIntersecting) {
header.classList.remove("nav-theme-2")
bttWrapper.classList.add("btnWrapperHidden")
bttWrapper.classList.remove("btnWrapperShow")
} else {
header.classList.add("nav-theme-2")
bttWrapper.classList.add("btnWrapperShow")
}
// console.log(entry.target, '-', entry.isIntersecting)
});
}, options);
mainObserver.observe(mainSection)
window.addEventListener("scroll", (event)=>{
console.log("scrolled")
var scroll = this.scrollY
if(scroll > 20){
console.log('reached')
}
})
const test = () =>{
console.log('working')
}
window.addEventListener("scroll", test)
window.addEventListener("scroll", () => console.log(window.pageYOffset));
Later in the lower part, I've tried to add scroll event in some ways but nothing is happening.
Here is the link for the whole repo: Github repo link

use min-height, max-height

Try this one
const main = document.querySelector('main');
// main.onscroll = logScroll;
main.addEventListener('scroll', logScroll)
function logScroll(e) {
console.log(`Scroll position: ${e.target.scrollTop}`);
if(e.target.scrollTop == 761){
console.log('About Page is Reached');
}
}
Note for target.onscroll
Only one onscroll handler can be assigned to an object at a time. For greater flexibility, you can pass a scroll event to the EventTarget.addEventListener() method instead.
As explained here https://developer.mozilla.org/en-US/docs/Web/API/GlobalEventHandlers/onscroll
As I understand here in my code above, the target.scrollTop will only works when you have selected a valid target in your document object. In this case as I inspect your html markup you have wrapped your whole sections to a main tag.
Now that's it, I tried to get your main tag and add an eventListener to it, and it works to me. Hope this also works to you.
