selectors don't work properly

[kopar]

for example on  http://docs.jquery.com/Selectors/input everything looks fine but when we look in firebug

$(":input").length returns 3 whereas it should return 3!!!

There are also similar problems with other selectors e.g $("input[name*=]")

I think you're confused. The demo that you see there is running in an iframe (thus when you run the query in Firebug it will only match the search boxes, etc. that you see on the page - not what's in the demo). Copy the demo source code to another page to try it.

Finally I found reason it hadn't worked - problem is when you use jQuery validation plug-in 1.4 by Jörn Zaefferer alng with Jquery 1.3

you can also remove bug 3912 that I created today
