What is the purpose of the preventDefault function in the provided code for Webflow?

The preventDefault function in the provided code for Webflow serves the purpose of stopping the default behavior of an event from occurring. When an event is triggered, such as a click on a link or a form submission, the browser typically handles it according to its default behavior. However, in some cases, you may want to modify or prevent this default behavior in order to achieve a specific functionality or user experience.

By invoking the preventDefault function within an event handler, you can prevent the default behavior of the event from happening. This allows you to take full control over how the event is handled, allowing you to customize the behavior as per your requirements.

Some examples of situations where you might use preventDefault in Webflow include:

1. Form submissions: If you want to perform client-side form validation before allowing the form to be submitted to the server, you can use preventDefault to stop the default form submission behavior. This gives you the opportunity to check the form inputs, display error messages, or perform any other custom logic before submitting the form.

2. Links and navigation: When you want to implement custom navigation functionality, such as smooth scrolling to an anchor section on the same page, you can use preventDefault to prevent the browser from navigating to the default target of the link. Instead, you can handle the event and scroll to the desired section using JavaScript or jQuery.

3. Drag and drop: If you want to implement your own custom behavior for draggable elements, you can use preventDefault to prevent the default drag behavior provided by the browser. This allows you to control the element's movement, position, or any other visual effect that you want to achieve during the drag operation.

In summary, the preventDefault function in Webflow's provided code allows you to take control over the default behavior of an event and provides you with the flexibility to implement custom functionality as per your requirements.
