HTML5 removes that restriction on id's, and I can't think of a single browser that even follows that restriction. There are a lot of convoluted things inside of the HTML4 spec which browsers don't bother implementing, and we don't bother following, nor do browsers. Saying that we shouldn't handle id's without [] because standards defines that we shouldn't, is like saying we shouldn't use innerHTML because it's not defined in standards.
Fact is that jQuery does support using characters like :[] by escaping them with a \ and that should be noted when someone does not know. ~Daniel Friesen (Dantman, Nadir-Seen-Fire) DBJDBJ wrote: > Thanks Nick, > > Also would not this forum be better without advices like : > > "...[] is used for attributes.
