However, if you've tried running it, you might find that it doesn't work as expected. This is often due to incorrect usage of quotation marks in your code, which can confuse the browser.

Step 2: Understanding the Code

Button Element: The <button> tag creates a clickable button.

onclick Attribute: The onclick attribute specifies what should happen when the button is clicked.

Alert Function: The alert("hi") function displays a simple pop-up alert box that shows the text "hi".

Summary of the Code

Button Creation: Use <button> for making a button.

Triggering Alerts: Use the onclick event to call JavaScript functions, in this case alert().

Proper Quotation: Make sure to wrap the alert message in double quotes (") while using single quotes (') for the onclick attribute, or vice versa.

Complete Example

You can add the following code snippet to your HTML file. It creates a button that, when clicked, shows an alert:

Conclusion

Creating a button that triggers an alert in HTML is straightforward once you understand the correct syntax. Because JavaScript relies on precise syntax, ensuring that your quotation marks are used correctly is crucial for your code to function properly.

Now you can enhance your web pages with interactive elements that engage users effectively. Happy coding!
