How To Name A Function In Jquery

by

When working with jQuery, it is essential to name your functions properly to ensure maintainability, readability, and ease of understanding for both yourself and other developers. In this blog post, we will discuss some best practices for naming functions in jQuery and provide examples to help you get started.

Best Practices for Naming Functions in jQuery

  • Use camelCase: In JavaScript, it is common to use camelCase for naming functions, variables, and objects. This means that the first word is in lowercase, and every subsequent word begins with an uppercase letter. For example, myFunctionName.
  • Be descriptive: Choose a name that describes the purpose of the function. This makes it easier for others (and yourself) to understand the code later. For example, instead of naming your function doStuff, use a more descriptive name like calculateTotalPrice.
  • Avoid abbreviations: Do not use abbreviations or acronyms that might be unclear to others. Instead, use full words to make your function names easy to understand.
  • Keep it short: While being descriptive is important, try to keep function names reasonably short. This makes the code easier to read and understand.

Examples of Naming Functions in jQuery

Let’s look at some examples of naming functions in jQuery. We will create a simple function that changes the background color of an element when it is clicked.

First, we will define our function using camelCase, with a descriptive name: 

        function changeBackgroundColor() {
            // Your code here
        }

Next, let’s use jQuery to bind our function to the click event for an element with the ID myElement. Notice how the function name is descriptive and easy to understand: 

        $(document).ready(function() {
            $('#myElement').on('click', changeBackgroundColor);
        });

Now let’s create another function that calculates the total price of items in a shopping cart. We will use a descriptive name like calculateTotalPrice instead of a vague name like doStuff: 

        function calculateTotalPrice() {
            // Your code here
        }

Finally, let’s assume we want to call this function when a user clicks on a button with the ID calculateButton. Again, notice the descriptive function name in the jQuery code: 

        $(document).ready(function() {
            $('#calculateButton').on('click', calculateTotalPrice);
        });

By following these best practices for naming functions in jQuery, you will make your code more readable, maintainable, and easier to understand for yourself and other developers. Happy coding!
