How to Invoke a JavaScript Function on the Content of a Div

In the world of web development, transforming text dynamically can enhance user experience and improve readability. One common requirement is to convert text to title case using JavaScript, especially in a WordPress environment. If you've found yourself asking, "How do I call a JavaScript function to transform the text within a <div> or paragraph?", you're in the right place.

Understanding the Problem

You have a script that defines a function to convert string text to title case. However, you need to know how to effectively link this function to the content of HTML elements such as <div> or <p>. It's crucial to achieve this without relying on CSS methods, ensuring that the JavaScript method manipulates the text as intended.

The Solution: Step-by-Step Breakdown

1. Define Your JavaScript Function

The first step is to ensure your function to convert the text to title case is defined. Below is the provided JavaScript function, toTitleCase, which is a prototype method for string manipulation. This method replaces the initial letter of each word with an uppercase letter while maintaining the rest in lowercase:
