I am going to use the ajax for simply refresh the multiple element on the page based on synchronous or asynchronous . I want to refresh the page When the ajax request in completed. Is there any ajax framework that has ajax utility function ? I did not use any javascript framework. Now I am developing page based on J2EE.
