Here is a small example with the masked input plugin :
//apply the mask to an input
$('.st').live('click', function() {
$(this).mask("99:99");
});
.st is a text input with a td, the use can clone the td. However, when you clone this td, and try to click in the .st of the new element, your gain the focus of the first .st and it’s not working.
I have tried several things, bind(), live(), and each() with no results.
New jQuery (since 1.3 or 1.4) can clone everything together with event bindings. See .clone() in documentation (supply true as a parameter)
You can always write a function binding everything to given elements and take care of it yourself.
