How To Add JavaScript To WordPress

JavaScript improves WordPress pages and posts’ functionality. If you need to show third-party services on WordPress pages and posts, you will need to embed JavaScript (hereafter "JS") for the said purpose.

By default, WordPress doesn't allow entering JS code in pages and posts. For this purpose, you can make use of the WordPress widgets. Another option is to go for a WordPress plugin that lets you add custom JavaScript to your site without altering the source code.

Imagine: you can increase your site's functionality by entering JS into pages and posts by installing a single WordPress plugin: Visual Composer Website Builder.

Why Add JavaScript Into WordPress Pages And Posts?

  1. As JavaScript is a client-side scripting language, the WordPress pages can serve features with ease, speed, and accuracy. By client-scripting language, we mean the execution of JS code in the browser. On the other hand, the code or script that runs on the server costs time and resources.
  2. Implementing JS on WordPress is easy. To get started, all you need is the code and a WordPress plugin, like Visual Composer.
  3. JS provides extended functionality. With third-party scripts, you can write and use JS codes to improve a page's functionality and security.
  4. Using JS extends your WordPress theme's features. As WordPress templates contain source code files, such as HTML, CSS, and JavaScript, the use of JS provides a competitive advantage.

How To Add JavaScript To WordPress Pages And Posts?

The process of adding JS to WordPress pages and posts consists of installing a WordPress plugin. Once completed, the process leads to creating JS code snippets in the plugin and adding them to WordPress pages and posts. Each code snippet is referred to by its shortcode, that you can insert into WordPress content.

So, let's proceed to the WordPress Plugins Directory to find the Visual Composer plugin so you can add JS to the whole WordPress site, a specific page, or post.

First, download the WordPress plugin file and upload it to your site. Alternatively, use the Add New Plugin feature in the WordPress dashboard. You can see the said option in the Plugins menu.

If you want to apply custom Javascript to the particular page or post, it can be more convenient to use a local (page-specific) inserting option. You can access it straight from the Visual Composer FrontEnd Editor - a true WYSIWYG live editor that represents how your content will look after you publish it.

By adding a custom JS code snippet locally, you specify what page or post your code will affect.
