[Proto-Scripty] Re: Observer problem
Hi rui, Your problem could be resolved using event delegation, you set the event on the body of you document. Whne the observed event is fired, you can know on which element it is applied. If the element is the element you *really* want to observe, just launch your code that handle that event. In that case, element could be removed (no more event could be fired) and can be re-inserted. In that last case, the element have changed, but for the event delegation, the only important thing is that the element.id exist, and the event is well fired without anything to do. -- david On 14 déc, 01:15, Rui Campos wrote: > Thanks for the reply, it solved my problem :) > > I moved the input box away from the part that I want to update and it > worked. > > Thanks again, > Rui Campos. > > On Dec 13, 10:03 pm, "T.J.

Thanks for the reply, it solved my problem :) I moved the input box away from the part that I want to update and it worked. Thanks again, Rui Campos. On Dec 13, 10:03 pm, "T.J.

Hi, If you're replacing the element you're observing, that's your problem -- events are observed on instances. Even if you replace an element with the ID "X" with another element with the ID "X", they're different elements. >From your description, it sounds like you're replacing more than you really should be, but it's hard to tell without code. If it's not that you're replacing the element you're observing, I'd suggest replicating the problem in a small, self-contained example[1].
