Prototype通用性方法-$w(String) -> Array

Splits a string into an Array, treating all whitespace as delimiters. Equivalent to Ruby's %w{foo bar} or Perl's qw(foo bar).

1 $w('apples bananas kiwis')
2 // -> ['apples', 'bananas', 'kiwis']

This can slightly shorten code when writing simple iterations:

1 $w('apples bananas kiwis').each(function(fruit){
2 
3   var message = 'I like ' + fruit
4 
5   // do something with the message
6 
7 })

This also becomes sweet when combined with Element functions:

1 $w('ads navbar funkyLinks').each(Element.hide);
