confirm

• The sample example for confirm
  

  window.confirm("Are you sure you want to quit?")
  

• Let's provide another example, where a confirm box will allow users to choose between going to two places:
  

  <script>
  <!--
  function ss()
  {
  var ok=confirm('Click "OK" to go to GS Travel experiences, "CANCEL" to go to GS Dot net faqs')
  if (ok)
  location="http://www.travelwithgs.blogspot.com"
  else
  location="http://www.gsdotnet.blogspot.com"
  }
  //-->
  </script>
