Why is My Alert Box Not Appearing in JSFiddle?

Troubleshooting a JSFiddle Issue: Absence of Alert Box

You encountered a problem while using JSFiddle, where a simple code snippet containing an alert function failed to display the expected message box. After isolating the issue, you realized the problem persisted even with the most basic code.

The solution to this problem lies in JSFiddle's JavaScript settings. Specifically, the "Load type" dropdown must be set to "No wrap - bottom of ". This setting ensures that the JavaScript code is placed at the bottom of the tag in the HTML document, preventing it from being wrapped in additional code or executed prematurely.

By selecting "No wrap - bottom of ", the JavaScript code is placed directly before the closing tag, ensuring it loads after the DOM has been parsed. This allows all elements to be created before the JavaScript code executes, ensuring that the onclick event handler can successfully reference the displaymessage() function.
