Ask for a confirmation in Javascript before a critical action

Question:

How can I prompt a user to confirm critical actions like deleting records?

Answer:

Use the javascript confirm() function. It looks similar to the alert() box, but has an OK and a CANCEL button.
If the user clicks OK, confirm() will return true.
Otherwise - escape, or click on CANCEL - it will return false.

<script language="JavaScript">
<!--
function confirm_entry(user_name, delete_url)
{
input_box=confirm("Do you really want to delete user " + user_name);
if (input_box==true) { 
  // clicked 'OK', so delete the record
}
}
-->
</script>

<a href="javascript:confirm_entry('peter', '/cgi-bin/delentry.pl?peter')">delete peter</a>

Yes ,I am from Cambridge US

I have a problem to submit online a document. My computer(Macos9) brand new keep telling me 'Javascript:ask for confirmation'. I don't really know how to to that and I can't submit my document until I fix this problem.So read your explanation but I am still confused. Could you technically tell me what to do?
Thank you for consideration
