  5. 5.  What is jQuery and Why should I care? jQuery Overview Deployment & Development Interacting with SharePoint & the DOM Reading / Writing SharePoint List Data Using Third Party Libraries Demos 5
  6. 6.  What / Why jQuery? ◦ JavaScript utility library supported by Microsoft ◦ Don‟t have to crack open Visual Studio or deploy solutions (ideal for SharePoint online and tightly controlled environments) ◦ It‟s the future
  7. 7.  What skills do you need? ◦ JavaScript ◦ CSS, XML ◦ A development background  It IS code  Uses development constructs  If you can‟t write code, your ability to do magic will be limited to what you can copy/paste ◦ CAML, CAML, CAML… Sorry… ◦ Ability to think outside the box  Use all the pieces together
  8. 8. Resolves many common SharePoint complaints without having to crack open Visual Studio
  9. 9. “It looks like SharePoint”
  10. 10. “That‟s SharePoint?”
  11. 11. “I‟m so sorry… SharePoint can‟t do that out of the box”
  12. 12. “Sure, no problem”
  13. 13. “That will take 3 weeks???” becomes “2 days?Awesome! I love you… here, please accept thisbonus for being such a wonderful developer”
  14. 14.  What you need to be aware of ◦ It is secure  It uses SharePoint‟s security. All scripts run with privileges of current user ◦ It performs well… if done correctly  Reduce postbacks  Can delay queries more effectively ◦ Privileges  They can not be elevated… thank goodness…
  15. 15.  What you need to be careful of ◦ It can perform horribly  Executes on client computer  Don‟t send too much data over the wire  Minify your scripts ◦ Inconsistent results  Different browsers  Network speed  Client machine differences ◦ Changes in the jQuery library ◦ It CAN harm your farm!
  16. 16. JavaScript DescriptionClasses / Objects var myCar = { id: 1, make: “Jeep”, model: “Wrangler”, color: “Silver” } var vehicles = {}; vehicles[myCar.ID] = myCar;For each loops For (car in vehicles) { var thisCar = vehicles[car]; }.split() Var numbers = “1,2,3,4,5”; Var myArray = numbers.split(“,”); myArray[0] == “1”.replace() var myString = “This string has spaces”; var newString = myString.replace(“ “,””); newString == “Thisstringhasspaces”;
  17. 17. Method Description$(document).ready(function($){ Where code execution begins after page is loaded})$(“#ElementID”) Returns element with given id$(“Type[attrib=„value‟]”) Gets element of specific type and attribute value $(“input[Title=„First Name‟]”).show(), .hide(), .toggle() Shows, hides, toggles.html() Gets the raw html for an element with tags.text() Contents of an element with HTML tags stripped out
  18. 18. Method Description.each(function() {}) Iterate through all elements that are found. $(“tr”).each(function() { }) would iterate through every row on the page..closest(selector) Get the first element that matches the selector, beginning at the currently element and progressing UP the DOM $("input[title=„Field Name]").closest("tr").hide();.contains() Check to see if a DOM element is within another DOM element.find() Get the child elements of current element, filtered by a selectorChaining:$("#WebPartWPDnn").find("nobr b:contains(Sum = )").html().split(" = ")[1].replace(",","");
  19. 19.  Deployment Options ◦ Document Library  Easily modify scripts  Keep track of changes with Metadata  Recover from screw ups with Versioning  Less control, more flexibility versus other options ◦ File System  Deployed with a WSP (don‟t think of manually copying)  Not an option for Office 365 or hosted SharePoint 2010 ◦ CDN
  20. 20.  ScriptLink  MasterPages, Delegate Controls, Web Parts, Controls, Custom Pages  Ensures Script is not loaded multiple times  Renders in the correct place in the markup  Need Visual Studio or SPD  More upfront work Content Editor Web Part (CEWP)  Quick & Easy  Don‟t have to deploy anything  Adds CEWP overhead
  21. 21.  Custom Action  Loads Script for entire Site Collection  Works in sandbox<?xml version="1.0" encoding="utf-8"?><Elements xmlns=""> <CustomAction ScriptSrc="~sitecollection/SiteAssets/jquery.min.js" Location="ScriptLink" Sequence="100" > </CustomAction></Elements>
  22. 22.  Development Tools ◦ IDE  Visual Studio  Notepad++  SharePoint Designer ◦ Debugging  IE Developer Tools  Chrome debugger  Fiddler  Alerts… lots and lots of alerts  Avoid Console.log (or use it wisely)
  23. 23.  View the DOM to understand what elements and classes exist on the page. “View page source” (Chrome) and “View Source” (IE) displays the contests of the DOM when the page is initially loaded. The DOM is always being modified, view the active DOM in your chosen debugger to view the DOM as it currently exists.
  24. 24. Getting/Setting SharePoint Form Fields  Text Boxes ◦ $(“input[title=‟My Text Field‟]”).val()  Selects ◦ $(“select[title=‟My Choice‟]”).val(mySelectValue);  Checkboxes ◦ $("input[title=My Check box]").removeAttr(checked); ◦ $("input[title=My Check box]").attr(checked,checked);
  25. 25.  SPServices vs. Client Object ModelFeature SPServices COMAllows CRUD against SharePoint List Data Yes YesWorks in SharePoint 2007 Yes NoWorks in SharePoint 2010 Yes YesWorks with Anonymous Access Yes NoComes with additional helper functions Yes YesWorks cross-site Yes No
  26. 26.  Tips for selection and integration ◦ Look for supported / document libraries ◦ Test in target browsers before implementing ◦ Duplicate file structure ◦ Test “vanilla” in SharePoint first
  27. 27.  Some of my favorites ◦ Content Slider - rd-showcase-a-jquery-plugin/ ◦ Formatted Tables - ◦ Modal Window - dal/ ◦ SPServices - ◦ Calendar -
  28. 28. And Nifty Stuff
  29. 29.  You don‟t have to be a SharePoint Guru It‟s Cheap It‟s Quick It‟s Easy It gets the job done
  30. 30.  Don‟t abuse it, You‟ll pay for it later Limited choices There are healthier options Adds page bloat Can slow your performance
