html - Multiple buttons with Javascript confirm and window.location

I want to make a list of text/buttons that prompts a box
with a yes/no-option when the user clicks it. If the user presses yes, they get
redirected to another site. If no, they are just prompted with a explaining they can't
continue without pressing yes.

This is what I
have as of now:

data-lang="js" data-hide="false" data-console="true"
data-babel="false">

class="snippet-code-html lang-html prettyprint-override"> type="text/javascript">

type="button" onclick="confirmation()" value="Go to
Google.com">





type="text/javascript">

type="button" onclick="confirmation()" value="Go to
StackOverflow.com"/>

Unfortunately,
this makes both buttons refer the user to stackoverflow.com. It always seem to apply the
last "window.location" to all buttons that I
add.

I would want each button to link to a
different site. Any help is greatly appreciated.
