What's the best way to replace links with JS functions?

Question

A pattern that\'s started to show up a lot in one of the web apps I\'m working are links that used to just be a regular a-tag link now need a popup box asking \"are you sure?\"

Answer 1

<a href="http://..." onclick="return confirm('are you sure?')">text</a>

Answer 2

Take a look at What’s the best way to open new browser window. You can do something similar, but throw up the confirmation prior to opening a new window.
