Hide All Elements With Class Using Plain Javascript

Are you looking to tidy up your website by hiding elements with a specific class using plain JavaScript? Well, you're in luck! In this article, we'll guide you through the simple steps to achieve this without the need for any additional libraries or frameworks.

To begin, let's first understand the concept of classes in HTML and how we can interact with them using JavaScript. In HTML, elements can have one or more classes assigned to them, which serve as identifiers for styling or scripting purposes. By leveraging JavaScript, we can manipulate these classes dynamically to hide or show elements based on our requirements.

Now, let's dive into the steps needed to hide all elements with a particular class using plain JavaScript.

Firstly, we need to select all the elements that have the specified class. We can accomplish this by using the `document.getElementsByClassName()` method. This method returns a collection of elements based on the provided class name.

let elementsToHide = document.getElementsByClassName('yourClassName');

Once we have obtained the collection of elements, we can iterate through them and apply the style property `display: none;` to hide each element.

for (let i = 0; i < elementsToHide.length; i++) {
    elementsToHide[i].style.display = 'none';
}

By setting the `display` property to `none`, we effectively hide the elements from view on the webpage. It's important to note that this approach alters the CSS `display` property directly on the elements themselves, overriding any existing styling that may affect visibility.

If you wish to toggle the visibility of the elements instead of outright hiding them, you can use a conditional statement in conjunction with the `style.display` property.

for (let i = 0; i < elementsToHide.length; i++) {
    if (elementsToHide[i].style.display === 'none') {
        elementsToHide[i].style.display = 'block'; // Or any other appropriate display value
    } else {
        elementsToHide[i].style.display = 'none';
    }
}

In this way, you can create a toggle effect that allows users to show and hide elements interactively.

Remember to adapt the class name in the code snippet to reflect the actual class you want to target in your HTML document. With these simple steps, you can effortlessly hide or toggle the visibility of elements with a specific class using plain JavaScript.

In conclusion, manipulating the visibility of elements based on their class using pure JavaScript is a powerful technique that enhances the interactivity and user experience of your web projects. By following the steps outlined in this article, you can easily implement this functionality and take your web development skills to the next level. So go ahead, give it a try, and watch your website come to life with hidden elements!
