def elsif(expression)
  self << "else if( #{javascript_for(expression) } ) {"
  yield if block_given?
  self << "}"
end

#if(expression) ⇒ Object

Produces if block, e.g.

page.if "$('element_id').visible()" do
  page['element_id'].hide
end

will produce

if( $('element_id').visible() ) {
  $("element_id").hide()
}

You can simplify if expression by using element proxies:

page.if page['element_id'].visible do
  page['element_id'].hide
end
