Thanks for the link http://docs.jquery.com/UI/Developer_Guide You are absolutely right about understanding.
Our professor of math was saying "First you have to use it, then you will understand it". I found it to be very true. I had been using JQuery for some time... It's just I am working on a new project which requires the tablesorter plug-in functionality married with AJAX. Unfortunately I were not able to use tablesorter as is. Since data comes from AJAX and tablesorter plug in does not allow me reload data into grid easily. I spent some time with it trying to fit it in but finally gave up and decided that it's time to write my own thing. And that is how I realized that I know too little about modern JavaScript language. I used to think that I know it pretty well when in reality all I could do is to use alert and setInteval functions :) George.
