How do I put a link to a webpage in a JScript Alert dialog box?

There was an error.  Go to this page to fix it.
wwww.TheWebPageToFix.com

if(window.prompt('Do you wish to visit the following website?','http://www.google.ca'))
  location.href='http://www.google.ca/';

if (window.showModalDialog)
   window.showModalDialog("mypage.html","popup","dialogWidth:255px;dialogHeight:250px");
else
   window.open("mypage.html","name","height=255,width=250,toolbar=no,directories=no,status=no,menubar=no,scrollbars=no,resizable=no,modal=yes");

alert("There was an error. Got to this page to fix it.nwww.TheWebPageToFix.com");
