Call 2 Functions Within Onchange Event

So you're working on a project and need to call not just one, but two functions within an `onchange` event in your code? Well, you're in the right place! Let's dive into how you can achieve this in your software engineering journey.

Firstly, what is the `onchange` event? This event is commonly used in web development to trigger a function when the value of an element has been changed. It's often used in forms, where you want something to happen based on user input.

To call two functions within the `onchange` event, you can simply create a new function that in turn calls the two functions you want to execute. Here's an example in JavaScript:

function handleChange() {
    function1();
    function2();
}

In this code snippet, the `handleChange` function is defined to call `function1` and `function2`. You can then attach this `handleChange` function to the `onchange` event of the desired element in your HTML code.

Let's say you have a select element in your HTML and you want to call two functions when the user selects an option:

<!-- options here -->

By setting the `onchange` attribute of the select element to `handleChange()`, you're instructing the browser to execute both `function1` and `function2` when the select element's value changes.

It's important to ensure that your functions `function1` and `function2` are defined and accessible in the scope where you're calling them. This means they need to be declared before the `handleChange` function in your code.

Remember, you can customize the `handleChange` function according to your needs. You might want to pass parameters to the functions it's calling or add additional logic inside `handleChange` itself.

By following these steps, you can easily call two functions within an `onchange` event in your code. This approach maintains clean and understandable code structure, making it easier for you and others to follow the flow of your program.

So, go ahead and implement this technique in your projects to add interactivity and functionality to your web applications. Keep exploring and experimenting with different ways to enhance user experience through dynamic events like `onchange`. Happy coding!
