 The solutions presented here
apply to all flavors of SharePoint 2007 and 2010 They can be installed via the standard SharePoint UI They rely on custom code, and are not available out of the box. However, many of them:  Are packaged, and can easily be installed by end users or power users  Are available for free

 Easy Tabs Color coded
calendar PivotTable

 High flexibility  Example:
color coded calendar Lighter to test and install Easy to remove – back to the OOTB behavior Client side interaction works offline Leverages resources outside the SharePoint world  Benefits from the active JavaScript community (e.g. jQuery plugins) Great way to empower the users and encourage user adoption

 Risk: users gone wild
 Solution: educate the users Method or hack (example: HTML Calculated Column) Doesn’t solve everything (permissions, access other domains) Issues with older browsers, or if the user turns off client side scripting Dependent on the original, OOTB Web Parts If the original HTML content is modified, the script needs to be executed again

 Get the script Upload
the script to the Site Assets library  Tagging Add a Content Editor Web Part Link the CEWP to the script [optional] Export the CEWP, upload it to the Web Part gallery

 Client side scripting is
a powerful addition to your SharePoint toolbox See it as a complement to server side options, rather than a competitor It is code that requires attention and maintenance, don’t be fooled by its apparent ease of use

 SharePoint User Toolkit 

 Sites regularly updated with
fresh, up-to-date content: jQuery Library for SharePoint Web Services – Marc Anderson, SharePoint MVP SharePoint JavaScripts – Alexander Bautz Path to SharePoint Search the Web for “SharePoint JavaScript” or “SharePoint jQuery”

 Allows users to embed
custom html in a SharePoint page HTML includes <script> and <link> tags Best practice: store the script in a central library and link to it

 jQuery is a popular
JavaScript library  Built on JavaScript  Strengths: ▪ Offers AJAX in a packaged, user friendly interface ▪ Addresses cross-browser inconsistencies ▪ Has prebuilt animation functions (fade, etc.)

 Recognition of AJAX as
a standard way to interact with the browser Development of JavaScript libraries that address cross-browser issues New generation of browsers with JavaScript engines that boost performance New standards that increase the features of client side scripting (e.g. canvas element)
