Mam jeszcze problemik z jQuery. Potrzebuję na stronce włączać/wyłączać wiersze formularza, w zależności od wyboru na liście <select>. Nie działa mi funkcja setBRTags() która włącza/wyłącza tagi <br clear="both"> (żeby nie tworzyła się pusta przestrzeń na formularzu). Oto ta funkcja:
function setBRTags() {
setCurrentStyle($('div[class="tip" style|="display: block"] + br[clear="both"]')[0], 'display', "");
setCurrentStyle($('div[class="tip" style|="display: none"] + br[clear="both"]')[0], 'display', "none");
}
Problem w tym, że oba wywołania $(...)[0] zwracają undefined, nie wiem co jest źle (jestem kiepski w jQuery). Wiersz formularza zawiera zawsze <div class="tip">...</div><br clear="both">. Chcę wyłączyć wszystkie br dla odpowiednich wierszy.
Wszystko jest na http://jsfiddle.net/rto26uvz/3/ ale nie umiem włączyć jQuery na jsfiddle. Jak by ktoś mi mógł pomóc...
