Retrieving Child Element's href Value in Vanilla JavaScript

In the world of web development, many of us have been spoiled by the ease and convenience that libraries like jQuery provide. However, as we move towards cleaner and more efficient applications, it's essential to gain a solid understanding of Vanilla JavaScript. One common challenge developers face is retrieving the href value of a child element. In this post, we'll explore a specific problem: converting jQuery syntax to Vanilla JavaScript.

The Problem

Consider a scenario where you have a JavaScript function that aims to retrieve the href attribute from a nested element whose class is pjt. Here's how you might typically achieve that using jQuery:

However, if you're transitioning away from jQuery and writing your code in Vanilla JavaScript, you may encounter an issue. Below is an example of an attempt that led to an error:

The Error

Running the code above produces the following error message:

This error arises because attr() is not a method in Vanilla JavaScript. Instead, we need to use the proper method to access attributes in this context. Let’s see how to correct it!

The Solution

To fix the error and retrieve the href attribute using Vanilla JavaScript, you should replace the .attr() method with getAttribute(). The getAttribute() method is a standard way to access the attributes of DOM elements in Vanilla JavaScript. Here's the corrected version:

Breakdown of the Solution

Using querySelector: The querySelector method allows you to select the first matching element within the target DOM node. In this case, we are targeting the element with the class pjt.

Getting the href Attribute: By using getAttribute('href'), you can retrieve the value of the href attribute from the selected element. This is the right way to access attributes in Vanilla JavaScript.

Conclusion

Transitioning from jQuery to Vanilla JavaScript can present challenges, especially when it comes to methods and syntax. However, with a little understanding and the right methods at your disposal, you can effectively handle DOM elements without reliance on libraries. The quick switch from .attr() to getAttribute() can save you from common pitfalls and enhance your JavaScript skills.

Remember, mastering Vanilla JavaScript not only improves your coding abilities but also opens up a new world of possibilities in web development. Happy coding!
