  1. Adding jQuery to Your WordPress Website

  2. jQuery is the most popular JavaScript library. It allows to highly simplify the front-end development as it offers a lot of ready-made plugins. Instead of creating something new, you can just add the plugin and solve any issue with the website.It is also very often used in WordPress to simplify the front-end part of the website. Moreover, it is even added to WordPress by default. When you install a new template for your website, you may face a situation where, due to the old version of jQuery connected to WordPress, the additional functionality you need does not work.

  3. What is jQuery? To better understand WordPress jQuery, the first thing you need to do is to brush up on your basics about javascript. It is one of the prominent languages that is generally used to make changes, do calculations and validate data on a website. In addition to that, with the help of javascript, you can also make changes or update HTML and CSS. In simple words, you can freely make rules and design your website structure and content.

If you are using WordPress, by default it is unable to understand “$” as jQuery, due to which it will trigger an error message “$ is not a function WordPress” error on your screen. It actually occurs when the code starts to execute just before the jQuery library. Let us understand it with an example, suppose a theme or plugin is calling a code before calling the right jQuery library, the error will occur.

  6. Using ‘$’ instead of ‘jQuery’ in WordPress The trick here is that by default the copy of jQuery works in a compatibility mode. This means that the well-known shortcut $ will not work. This is done not to create conflicts with other JavaScript libraries using the dollar sign, for example, MooTools or Prototype. Many plugin creators and theme developers know about this and use jQuery instead of ‘$’ to make the product secure.

  7. How to Add jQuery to WordPress Custom Theme or Plugin? To run the jQuery scripts on the WordPress website, you need to add the appropriate libraries. But fortunately, the WordPress structure already includes all the necessary libraries. To make them work, you just need to connect them to your theme.
