Re: Re: Re: Re: Re: Re: Nokogiri#css("input:disabled") not working
So here is something I don''t quite understand. According to [1],
"input:disabled" is a quite valid CSS selector.
Given this[2]:
<html><body>
<style>input:disabled {background: #0F0; color: #F00;}</style>
<input type="text" id="greenjunk"
name="greenjunk" value="nada" disabled />
<input type="text" id="name" name="name"
value="Joe" />
<input type="submit" id="submit"
name="submit" value="submit" />
</body></html>
Why wouldn''t doc.css("input:disabled") also work? Clearly it
doesn''t,
but I don''t know what it *should* be. (Noting that xpath would be quite
different, of course.)
