Chapter 2 > Consuming Promises > Progress |
About the .progress() method, it states:
$('#something').animate({..., progress: function(){ ... })
is equivalent to:
$('#something').animate(...).promise().progress(function(){ ... })
I've tried this and it does not work. Am I doing something wrong or is this statement incorrect?
It seems like other people are confused about this too: http://stackoverflow.com/questions/22114493/why-is-this-jquery-promises-progress-callback-not-called-during-animation
Note from the Author or Editor:
Hello. Thanks for taking the time to dig into this and to post here. You are correct, it looks like the book is in error here. It seems that the 'notify' method on the promise is not called at all, so callbacks added via 'progress' are never called.
The workaround solution offered by Anup Vasudeva on the StackOverflow page you mention (http://stackoverflow.com/questions/22114493/why-is-this-jquery-promises-progress-callback-not-called-during-animation) is the way we'd also suggest dealing with the problem.
Apologies for the inconvenience, and thanks again. I hope you're enjoying the book, despite this error!
