jQuery Forum

It's not clear where those numbers are coming from without seeing the code.

If you think you've found a bug, first check the bug tracker at bugs.jquery.com to see if it has already been reported. If not, go to jsfiddle.com and create a test case that shows the problem, and create a new ticket. If it turns out to be a Sizzle issue we'll pass it along.

yeah, those numbers are from some random page on my website. i'll try to make a simple testcase. thanks.

I made a testcase. Its not really beautiful, but maybe enough to illustrate my question: jsfiddle
Just click on the firebug-icon in the right-bottom corner to see the results. (sometimes the console is empty, dunno why, try to use Ctrl+F5)

i modified the current jquery 1.4.4 release to get these results. so some explanation:
- selectors are all selectors passed to jquery (not really interesting i think).
- prematchcounter, prematchelements are elements that are passed to Sizzle.filter function line 3229.
- counter, elemtents are elements that match in Sizzle.filter line 3238.

so, the main difference is, that in firefox only one element is passed to Sizzle.filter and in internet explorer 8 and opera there are 4 elements. for firefox the one element doesnt match. for ie8 there are 4 matches for CLASS, 1 for PSEUDO and 3 for TAG. In opera there are 3 matches for CLASS and 3 for TAG.

to be honest, i have no idea of jquery internals nor sizzle internals. i just try to understand and maybe somebody can explain this different handling in the browsers.
