What's this?

[](id) public

Returns a element reference by finding it through id in the DOM. This element can then be used for further method calls. Examples:

page['blank_slate']                  # => $('blank_slate');
page['blank_slate'].show             # => $('blank_slate').show();
page['blank_slate'].show('first').up # => $('blank_slate').show('first').up();

You can also pass in a record, which will use ActionController::RecordIdentifier.dom_id to lookup the correct id:

page[@post]     # => $('post_45')
page[Post.new]  # => $('new_post')
