waiting for empty animation queue
.wait(null / $ ,callback)

.wait(null / $ ,callback)

null / $ – undefined or the jQuery token, optional

callback – function(count…), optional

a method that is called once before continuing the jQuery chain.

All current iteration counts/events (from inner-most to outer-most loop) are passed as arguments.

Tip: .wait() is an abbreviation for .join(true). The join() method provides more options when waiting for animations.

Usage pattern

$('.some').wait().doSome().jQueryStuff();
