The feature finds possible matches to search terms as the user types. While it may seem old now, it was a Google innovation. Suggest was first created in 2004 and made developers clamor to figure out how it was done. This was before the term “Ajax” was coined and well before it was overused.
Google does not make a homepage change lightly. For this reason, many assumed Suggest would never be made the default experience of most users who go directly to Google.com to search.
Among the most exciting proposed features slated for the next version are DOM manipulation APIs, which make it easy to access any elements in a web page. The company also plans to translate some server-side controls to be accessible via client-side calls. For example, a templating control could retrieve data from the server and place it into a page based on a local template without refreshing.
On the list of nice-to-haves, Microsoft includes animation and drag & drop. These popular features are a major part of effects libraries such as Scriptaculous, Moo and JQuery.
Developers attempting to use non-Microsoft tools have long had difficulty fitting in with the ASP.NET framework. For example, ASP.NET changes the ID of any server-manipulated page element. The DOM features alone in the proposed update to Microsoft’s Ajax tools will simplify client-side access.
