Do i need $.ajax async:false if using success: callback function?

[nelsonm]

Hi all,

I was looking over my code and noticed that i had jquery .ajax methods that had the async:false setting in a few javascripts.

So i looked it up on the jQuery site and it said that As of jQuery 1.8, the use of async: false is deprecated. Why would it be depreciated?

I'm not sure i even need async:false, doesn't using a callback function as the success setting value negate the use of async:false?

thanks,

Provided the code following the ajax call does not rely on the completion of the ajax, the async:false can be removed, such code should be in the callback.

what's the idea behind async:false being depreciated anyway?

It's because synchronous requests can lock up the ajax state and browser. IMO it should been like this from the beginning and have the code serialize the ajax requests if necessary.

ok, thanks....

I changed all my scripts to remove the potential problem and every thing still works.
