Question

As in this screencast ( http://www.youtube.com/watch?v=h0uZIljjElo ), I think I often see jQuery syntax being used to wrap and define functions that don’t benefit from jQuery. E.g.:

<script>
  $(function() {
    // some code to run at load time
  });
</script>

It would be shorter to write the code without the 2nd and 4th lines. Is there some value in writing after this fashion?

Answer 1

This statement is a document ready statement, which is basically saying “Please don’t run any of the code inside this block until the DOM is ready to be manipulated.”
