-/* document.getElementsBySelector(selector)
- - returns an array of element objects from the current document
- matching the CSS selector. Selectors can contain element names,
- class names and ids and can be nested. For example:
-
- elements = document.getElementsBySelect('div#main p a.external')
-
- Will return an array of all 'a' elements with 'external' in their
- class attribute that are contained inside 'p' elements that are
- contained inside the 'div' element which has id="main"
-
- New in version 0.4: Support for CSS2 and CSS3 attribute selectors:
- See http://www.w3.org/TR/css3-selectors/#attribute-selectors
-
- Version 0.4 - Simon Willison, March 25th 2003
- -- Works in Phoenix 0.5, Mozilla 1.3, Opera 7, Internet Explorer 6, Internet Explorer 5 on Windows
- -- Opera 7 fails
