In this intro-level session on utilizing jQuery with SharePoint, the focus will be to empower users on how to satisfy some of the common UI changes clients request by writing clean and unobtrusive Javascript with the help of the jQuery library. We'll begin by diving into the different ways that jQuery can be hooked up to SharePoint. We'll talk about CDN versus local copies of the library, as well as linking jQuery via masterpages, custom actions, content editor web parts, and more. We'll then spend time discussing css selectors, and some of the common patterns and jQuery methods you'll want to familiarize yourself with when targeting page-level elements. After that, the remainder of the presenation will be focused on walking through real-life scenarios of altering the UI with jQuery, such as adding interaction and animation to content query webparts, changing the behavior of links inside a page, and more. The code utilized in the presentation will be made available online after the Conference is completed.

8. jQuery and Microsoft
• Microsoft contributes to the jQuery Project
• Microsoft Product Support includes jQuery
• jQuery ships with Visual Studio 2010+
• Visual Studio Intellisense Support

9. Intellisense Demo

10. Downloading jQuery
• Local Copy
◦ Download from http://jquery.com/
◦ Current and Past Releases
• CDN (Content Delivery Network)
◦ Google
◦ Microsoft
◦ jQuery

11. CDN Considerations
• CDN Advantages
◦ Quicker Downloads
◦ More Parallel Downloads
◦ Increased Use of Cache
• CDN Disadvantages
◦ CDN Outages
◦ Loss of Internet Connection
• Fallback Option to Load Locally When CDN Fails

12. Usage Guidance
• Use Minified Versions in Production
• Consider Local Storage Over CDN for Intranets
• Clearly Mark Your Version(s) of jQuery
• Test Thoroughly When Upgrading Versions
• Be as Unobtrusive as Possible

13. jQuery Conflict
• $ is an Alias for the jQuery function
• Many Libraries Use the $
◦ CmsSiteManager.js (SharePoint’s Asset Picker)
◦ Prototype.js
• Conflict Occurs When jQuery Overwrites Other
Library’s function
• Solution: jQuery.NoConflict()

14. jQuery.noConflict()
• Removes jQuery’s use of the $ function
◦ Returns Control of $ to Other Libraries
◦ jQuery method can be used in place of $
◦ Alias jQuery By Capturing Return Value
◦ var jQ = jQuery.NoConflict();
◦ Pass $ to Ready Method For Scoped Usage

15. Adding jQuery to SharePoint
• MasterPage (Or Page Layout)
◦ Adds Unnecessary Overhead On Pages That Don’t Use jQuery (if any)
◦ Does not Touch Pages That Do Not Utilize Your MasterPage
• Content Editor WebPart (Or Custom WebPart)
◦ Becomes a Burden to Manage References and Consistent Use
◦ Use the Content Link Versus Inline Code
• Delegate Control
◦ Alternate Solution Exists in SharePoint 2010 (See next item)
• CustomAction (New in SharePoint 2010)
◦ Breaks Asset Picker without Additional Configuration
• Start.js
◦ jQuery Is Not Available At Page Load
