JavaScript Function Not Triggering on Link Click: How to Resolve

When attempting to load content into an iframe by clicking a link in a sidebar navigation, users often encounter an issue where the JavaScript function fails to execute. Upon investigation, it was discovered that the primary cause of this problem was the omission of parentheses after the function name.

It is important to note that inline HTML event attributes are generally considered poor practice in web development. They can lead to tangled code, duplication, and can affect the overall maintainability and efficiency of the application.

Instead of using inline event handlers, it is recommended to separate HTML and JavaScript concerns and use the .addEventListener() method to attach event listeners to elements. This approach keeps code organized, scalable, and conforms to best development practices.

Additionally, it is important to consider using a button element instead of a hyperlink for this purpose. If a hyperlink is used, it is necessary to disable its default behavior of navigating to a new page by setting the href attribute to #, not "".

By addressing these issues and following best practices, you can ensure that your JavaScript function will execute corretamente when users click on the link in the sidebar navigation.
