Forum: Rails Spinoffs (closed, excessive spam) new Element vs Builder.node

Why there are Builder.node from scriptaculous if threre are exists new
Element?

Which one should I use to create a DOM elements and then append it to
some other element?

Builder.node() boils down to DOM operations, but it's a handy DSL for 
doing
nested element creation without creating all the intermediate objects 
and
gluing them together:

  document.observe('dom:loaded', function() {
    $('stuff').update(
      Builder.node('table', {id: 'mytable'}, [
        Builder.node('tr', [
          Builder.node('td', 'cell 1'),
          Builder.node('td', 'cell 2'),
          Builder.node('td', 'cell 3')
        ])
      ])
    );
  });

Or if you do Builder.dump() first:

  Builder.dump();
  document.observe('dom:loaded', function() {
    $('stuff').update(
      TABLE({id: 'mytable'}, [
        TR([
          TD('cell 1'),
          TD('cell 2'),
          TD('cell 3')
        ])
      ])
    );
  });

You're free to use whatever method you like best. :-)

Don't forget the template class. If you are building the same HTML 
structure
again and again, then a template works really well.

Yes, and will be faster in many cases, due to the fact that it generates
HTML markup, and takes advantage of the blazing fast performance of 
setting
.innerHTML.
