Subject: Only do the hasAttribute check if the method exists - IE falls back to the === null... 
X-Git-Url: http://git.asbjorn.biz/?a=commitdiff_plain;ds=sidebyside;h=a384d840d609a8ee25b8ca8769a99c33c73b022f;p=jquery.git

Only do the hasAttribute check if the method exists - IE falls back to the === null check below which allows this to still work. Follow-up to cb40495b21bcb7802f3ab6ae0f837f2bf5b385ed - thanks to @jitter for the catch.
