Why YOU might use jQueryHow to update VS-2008 for jQueryWrite some jQuery code Ideas for debugging jQuery codeReferences

Sam Nasr has kindly agreed to post these slides on http://www.clevelanddotnet.info/.

Javascript has become essential to current web page development, but …

Javascript is not a good language design

Javascript has become bloated DOM navigation Browser differences

Writing Javascript code is tedious, time-consuming, and error-prone

jQuery makes writing Javascript much easier DOM navigation (css-like syntax) Apply methods to sets of DOM elements Builder model (chain method calls) Extensible and there are tons of libraries Handles most browser differences so you

don’t have to Server provides data jQuery on client provides presentation

Scott Guthrie announced “… that Microsoft will be shipping jQuery with Visual Studio going forward.  We will distribute the jQuery JavaScript library as-is, and will not be forking or changing the source from the main jQuery branch.  The files will continue to use and ship under the existing jQuery MIT license.

We will also distribute intellisense-annotated versions that provide great Visual Studio intellisense and help-integration at design-time”

A problem with Google is that it finds outdated information as easily as current information. Integration with Visual Studio 2008 is improving quickly. Be wary of old hints. Some are unnecessary. Some break things.

Go code some cool web pages using jQuery.

Thank you.
