I want to create a page where the top half contains start stop buttons and in the bottom half i want to write content from the server. the buttons invoke functions on the server and the server does some computing and generates timely messages which need to be written to the bottom half of the page.
Possible ways of doing
1. AJAX
2. DWR
3. HTML5
Let me know which method is better and how can i do it.
Means “Making an HTTP request without leaving the page”. This will let you get content from the server. To write it you need to do DOM manipulation. There are no shortage of Ajax and DOM tutorials on the web
Is a library to help with Ajax (although not one I’ve heard of before).
Is a now meaningless buzzword. Of all the meanings it has, only the ones which include “Ajax and DOM manipulation” will help, and that’s already covered above.
