Would like to know proper way to write a function that will open an alert dialog with the message "Warning!".

Would like to know how I can add this function between body tags.

index.html 
<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  <title>JavaScript Basics</title>

<body>
<script>Alert.("Warning!");
  </script>
</body>
</html>

Hello Michael, the problem with your script is that the alert syntax is wrong. It goes this way:

<script>alert("Warning!");
    </script>

You have a syntax and a spelling issue:

  • there should not be a period between the function name and the parentheses containing the argument
  • JavaScript is case sensitive, and you wrote "Alert" (with a capital "A") instead of "alert"
