Get an article's title/author/date info with Javascript

Question

I'm trying to build a bookmarklet that will get the current page/article's author and date information, for referencing purposes. I know that I can get the Page title and url with document.title and document.URL but I'm drawing a blank when it comes to the other information. Any ideas?

Answer 1

Does the HTML has a predefined format ? If yes , you could maybe parse the HTML or query the DOM to get the other info that you need .

Answer 2

If the site puts such information in a META tag you can do this:

var author = "";
var info = document.getElementsByTagName('META');
for (var i=0;i<info.length;i++) {
  if (info[i].getAttribute('NAME').toLowerCase()=='author') {
    author = info[i].getAttribute('CONTENT');
  }
}

For the site you mention in your comment, you need to do this non-standard processing

  var author = "";
  var other = document.getElementsByTagName('li');
  for (var i=0;i<other.length;i++) {
    if (other[i].className.toLowerCase()=='author') author=other[i].getElementsByTagName('a')[0].innerHTML;
  }
  alert(author)
}
