Nu se incarca corect paginile in IE /Firefox, in cazul in care avem un tag <script type="text/javascript" src="MyScript.js" /> in pagina (head/body, nu conteaza)

Trebuie schimbat in

<script type="text/javascript" src="MyScript.js"></script>

Apelarea paginii parinte dintr-o fereastra(popup) deschisa cu window.open

se foloseste opener (ex: opener.javascriptFunction())

$(this).data('events').click

URL-encoding

Pot folosi encodeURI, encodeURIComponent, sau escape.

parseInt('08'), parseInt('09') intorc 0 in loc de 8 respectiv 9

Trebuie specificata baza in care se face conversia => parseInt('08', 10), altfel javascript crede ca numerele sunt in baza 8.
