Callback function to be executed after jQuery show / hide?

Question

In iOS, the following code has a noticeable flicker between the hide() and the scrollBy():

element.hide();
window.scrollBy(0, -elementHeight);

Answer 1

Either pass a duration and a callback, or just pass a callback option, like this:

element.hide(0, some_function);

// or 

element.hide({done: some_function});

By default, the second option takes 400 ms. To do it immediately, use one of these:

element.hide(0, some_function);

// or 

element.hide({duration: 0, done: some_function});

Here's a jsFiddle demo.

See the jQuery documentation for more details.
