Hello, friends! Please kindly note that I eagerly read Larry's book on Javascript, but as a beginner, I struggled with the AJAX and Ajax-related chapters. As a result, I purchased and read--and loved-- Larry's book on AJAX.
However, and please forgive me for the lack of wherewithal, but I had some very basic questions:
1. What are the benefits of using AJAX and Javascript for form submissions/validation as opposed to simply relying on PHP? Is the benefit remarkable or catered to certain applications?
2. What are the various applications that Ajax allows for that could not be achieved with PHP alone?
Thank you very much for your kind and helpful responses.
