Question

What is the reason for the malfunctioning of this button upon clicking?

Attempting to customize my personal website by making the sidebar width change when the sidebar button is clicked. I'm puzzled as to why it's not working as intended. I prefer to figure it out independently but any helpful tips would be appreciated. I'm still a beginner and don't want to get into complex changes that may be too advanced for my current level, as I've only been learning for a few weeks.

const sidebarBut = document.querySelector('.sideBarBut');
sidebarBut.addEventListener('click', animate);

function animate(){
    document.querySelector('.sidebar').style.width = "400px";
}

/*--------|--------*/
.sideBarBut {
    transform: scale(0.065);
    background-color: black;
    position: fixed;
    bottom: 742.5px;
    left: -235px;
    cursor: pointer;
}

.sideBarBut:hover {
    filter: brightness(80%);
}

.sidebarTitle {
    color: white;
    position: fixed;
    top: -50px; /*7px*/
    left: 95px;
    font-size: 28px;
    font-family: sans-serif;
    text-decoration: underline;
    text-underline-offset: 4px;
    text-decoration-thickness: 2px;
}

.sidebar {
    z-index: 1000;
    height: 100%;
    width: 0;
    position: fixed;
    top: 0;
    left: 0;
    background-color: black;
    border-right: 0px solid transparent;
}

.animate {
    animation-play-state: paused;
    animation-name: sidebarOpen;
    animation-duration: 1s;
    animation-fill-mode: forwards;
}

@keyframes sidebarOpen {
    0% {
        width: 0;
    }
    100% {
        width: 250px;
        border-right: 2px solid white;
    }
}

@keyframes sidebarClosed {
    0% {
        width: 250px;
    }
    100% {
        width: 0;
        border-right: 0px solid transparent;
    }
}

.projectLinks {
    width: 200px;
    position: fixed;
    top: 40px;
    left: -1000px; /*20px*/
    color: white;
    list-style: none;
    padding-left: 0;
}

.projects {
    text-decoration: none;
    color: inherit;
    font-size: 20px;
    font-family: sans-serif;
    line-height: 30px;
}

.projects:hover {
    color: rgb(200, 200, 200);
}

            <div class="sidebar animate">

Answer №1

I noticed an error in your code. Instead of using animate, you should be using animate() instead. To avoid confusion, simplify

document.querySelector('.sidebar').style.width = "400px";

into something more understandable and functional. Here's an example:

function animate(){
let sidebar = document.querySelector('.sidebar');
sidebar.style.width = '480px';

Fixing the Error

After analyzing the issue, it seems that if you want the sidebar's width to smoothly transition from 0px to 400px upon clicking a button, you can resolve it by removing the "animate" class from the HTML element

<div class="sidebar animate">

or from the corresponding CSS block.

.animate {
    animation-play-state: paused;
    animation-name: sidebarOpen;
    animation-duration: 1s;
    animation-fill-mode: forwards;
}

By eliminating the "animate" class, the animation will be controlled by the styles directly assigned to the "sidebar" class, allowing your code to function as intended.

Other Suggestions for Improvement

Personally, I advocate for a concise approach in writing JS code, particularly when the logic is simple and not meant for reuse. In such cases, keeping the code succinct and integrated within the event listener can be more effective.

const sidebarBut = document.querySelector(".sideBarBut");

sidebarBut.addEventListener("click", () => {

  const sidebar = document.querySelector(".sidebar");
  sidebar.style.width = "400px";

});

If your aim is to trigger the animation upon button click, it may be more appropriate to modify the .animate class instead of the .sidebar class. Here is an adjusted version of the JS code to achieve this:

const sidebarBut = document.querySelector(".sideBarBut");

sidebarBut.addEventListener("click", animate);

function animate() {
  const sidebar = document.querySelector(".animate");
  sidebar.style.animationPlayState = "running";
}

Alternatively, you can dynamically add or remove the animate class to the sidebar element to exclusively control the animation for the sidebar without affecting other elements. This method offers precise management over when the animation should occur. Here's an example JS code snippet:

const sidebarBut = document.querySelector(".sideBarBut");

sidebarBut.addEventListener("click", () => {

  const sidebar = document.querySelector(".sidebar");
  sidebar.classList.add("animate");

});

Remember to ensure the .animate class has the necessary properties like

animation-play-state: initial || running;

for proper animation execution. By toggling this class selectively, you can have better control over the animation while managing the appearance of other elements on the page.

I hope these suggestions assist you in resolving the issue!
