Is there any other way for synchronisation instead of using wait statement for AJAX appliciation?

As in AJAX, only the object refreshes instead of browser and page, what should be the object property to be checked (if the object is web element) for waiting in the loop?

I tried with exist property of the object, but it is saying object not found if it takes long time to load the object? Can anyone please give me a solution.
