Picking an Ajax Framework
After initial review GWT was eliminated due to the legacy team division of UI and back end developer along with the requirement of learning a new Java based API. DWR was also eliminated due to the patch needed for the version evaluated to work with the Websphere Application Server used by T. Rowe Price. This left Prototype, Dojo, and Yahoo UI for continued evaluation.
- Dojo 0.3.1 (dojotoolkit.org).
- Prototype and Scriptaculous 1.4 (www.prototypejs.org and script.aculo.us).
- Direct Web Reporting 1.0 (getahead.org/dwr).
- Yahoo! User Interface Library 0.11.1 (developer.yahoo.com/yui).
- Google Web Toolkit 1.0 (code.google.com/webtoolkit).
The case study then goes on to compare how each framework fulfilled the requirements of creating a tabbed ajax widget and a dynamic "hub" widget with a title bar. All three required custom work for the desired tab widget functionality with Dojo providing the closest functionality out of the box. The team then moved on to look at load times:
Finally the team looked at overall ease of development. The consensus was that Dojo provided more features and widgets but customization was harder due to the number of files needing modifications. Yahoo UI was ultimately choose due to its well documented code and detailed tutorials on the Yahoo website.
But in my opinion, DWR is best ajax framework if there are no requirements to have fancy widgets may be just tables on view pages that refreshes asynchronously
