How to Convert jQuery Click Triggers to Pure JavaScript

As web developers, we often find ourselves relying on libraries like jQuery for ease of use and convenient functions. However, with the evolution of JavaScript, many developers are transitioning to pure JavaScript for enhanced performance and reduced dependencies. One common task is converting jQuery click triggers into vanilla JavaScript. In this guide, we’ll explore how to do just that.

The Problem: jQuery Click Trigger

Let’s say you have a jQuery snippet that looks like this:

In this code, when the element with the ID classone is clicked, all <li> elements will toggle a class named visible. While this code is concise and effective, many developers are moving away from jQuery for various reasons, such as reducing file size and improving performance.

The Solution: Using Pure JavaScript

To achieve the same functionality using pure JavaScript, we can utilize the addEventListener method for handling events, along with querySelector and querySelectorAll to select the relevant DOM elements. Here’s how you can convert the jQuery code to plain JavaScript:

Step-by-Step Conversion

Add Click Event Listener: Use addEventListener to listen for click events on that element.

Explanation of the Code

.addEventListener("click", function() {...}): This attaches a click event to the selected element. The anonymous function will execute when the element is clicked.

.forEach(function(elem) {...}): The forEach method iterates over the NodeList of <li> elements, allowing us to perform actions on them.

Conclusion

Switching from jQuery to pure JavaScript can be a rewarding process, making your code cleaner and potentially increasing performance. By following these steps, you can easily convert jQuery click triggers to vanilla JavaScript functions. Embrace the power of modern JavaScript and streamline your web development projects!
