#select(*selector) ⇒ Object

selects elements on the page using css3 selectors For more info: www.w3.org/TR/css3-selectors/ A few useful examples: ‘div’ would select all divs. ‘.full’ would select all elements with class ‘full’. ‘div.blah’ would select all divs with class ‘blah’. ‘#foo’ would select the element with id ‘foo’

select can take multiple selector strings. For instance page.select(‘ul.blah’, ‘#foo’, ‘.full’) would give you access to a collection of elements containing all uls with class ‘blah’, the element with id ‘foo’ and every element with class ‘full’. See JquerySelector or PrototypeSelector for available methods on the returned collection.
