How to Import jQuery from a Separate File: A Step-by-Step Guide

If you're embedding jQuery code directly into your HTML file using <script> tags, you may find it cumbersome and inefficient, especially as your projects grow in complexity. In this guide, we’ll address a common question among web developers: How do you import a jQuery script from a separate file, so you can keep your JavaScript organized and your HTML clean?

The Problem

You may have previously written your jQuery code inline like this:

While this works for small snippets of jQuery code, it can quickly become unwieldy for larger projects. What you want to do is move this logic into a separate JavaScript file, for example, test.js, and then import that file into your HTML.

The Solution

To accomplish this, you need to follow a straightforward process. Here’s a step-by-step guide on how to import jQuery from an external file.

Step 1: Create Your JavaScript File

First, create a JavaScript file named test.js. Inside this file, place your jQuery code. Here’s an example:

Understanding the Code

Importing jQuery: The first <script> tag includes the jQuery library. Make sure that the path to your jQuery file is correct.

Importing Your Script: The second <script> tag imports your custom JavaScript file, test.js. Ensure that the path matches the location of your JavaScript file.

Avoiding Inline Scripts

By separating your JavaScript into a filed script, you can keep your HTML clean and more readable. You also reduce redundancy and make maintaining your code easier by working in single files that are dedicated to specific functionality.

Conclusion

By following these steps, you can import your jQuery scripts from a separate file with ease. This method not only promotes better organization but also enhances the maintainability of your code in the long run. Embrace this practice, and start writing clean, manageable code today!
