html - Creating a web application, then adding Ajax to it? -

-

i imagine there many of out there have developed application online automates lot of processes , saves people @ company time , money.

the question is, experiences developing application, having set in place, "spicing" ajax, makes better user experience?

also, libraries suggest using when adding ajax already-developed web application?

lastly, common processes see in web applications ajax with? example, auto-populating search box type.

my preferred way of building ajax-enabled applications build old-fashioned way every button, link, etc. posts server, , hijack button, link, etc. clicks ajax functionality.

this ensures app down-browser compatible, good.
