Adding jQuery to Your Theme or Plugin
The first step is to decide how you’re going to add the jQuery code. If you’re adding it directly into your theme, then you’ll need to open up your functions.php file and paste in the following code, replacing “jquery_file” with the path of your actual file:
Using CDN Instead of Local Files
You can also opt for using a CDN (content delivery network) instead of hosting the files locally. This allows visitors from different parts of the world access files more quickly since they are being served from multiple locations around the world instead of just one server location. To use CDN instead of local files, simply replace “get template directory uri()” with “wp jquery cdn url()” in either method mentioned above.
Adding jQuery to WordPress isn’t as hard as it seems! Whether you’re adding it directly into your theme or using a plugin, there’s an easy way to get started with minimal effort and time investment. With just a few lines of code and some strategically placed files, you can enhance any website’s functionality with ease—and benefit from all that jQuery has to offer! Good luck!
