3. Session Overview SharePoint’s pages and forms can seem somewhat old- fashioned to the Facebook generation. By using jQuery, jQueryUI, and other scripting libraries such as SPServices, we can make those pages more consistent with the type of user experiences people are used to on the modern Web. In this session, Marc will cover some of the useful features of jQuery and SPServices as well as some of the rich possibilities available to you by demonstrating solution examples he has built for his consulting clients. This demo-rich session is bound to change the way you think about building your SharePoint applications.

4. Getting Started

5. What is jQuery? is

6. Getting Started Add references to the jQuery library References can be in: Master page Page layout Individual aspx pages jQuery and other.js files can be stored in: Document Library _layouts folder Retrieved from a CDN Use “protocol-less” src and href

7. Script from CDNs Referencing jQuery, jQueryUI, and SPServices from CDNs – Revisited http://sympmarc.com/2013/02/07/referencing-jquery-jqueryui-and-spservices-from-cdns-revisited/

8. HTML Elements Powered by Office365. Opening tag Closing tag AttributeValue Element Self-closing tag IdAttributePropertyValue Class(es)

9. What is the Document Object Model (DOM)? The DOM starts as the page’s markup (HTML) as delivered to the browser by the server: View Source Styled by the CSS which gives the page its look and feel The DOM is acted upon by any script in the page View Source is *not* the live DOM

10. What Can We Do With the DOM? Add or remove CSS classes Create new or remove existing HTML elements Change HTML element attributes Bind to events And so much more… The DOM is HTML, which is XML, which is data!

11. The Basic Idea of jQuery $('.article').hide(); Select something Do something! Remember this from CSS?

12. jQuery’s Document Ready $(document).ready(function() { // do something }); jQuery(function($) { // do something });

13. jQuery Documentation: Your Friend The jQuery documentation is used to be arranged to help you What you need to know is was arranged sequentially from top to bottom

14. jQuery Selectors Selectors are the most important jQuery concept Selecting the right DOM object(s) is half the battle Selectors return a jQuery object containing a collection of DOM objects: 1 to n matching elements

15. Selectors for SharePoint $("div[id$='QuickLaunchNavigationManager'] li:first span.menu-item-text")

16. Selectors for SharePoint $("td.ms-list-addnew a:eq(1)")

17. Useful jQuery Selector Tricks $("[id='foo']");// Equal to $("[id!='foo']");// Not equal to $("[id^='foo']");// Starts with $("[id$='foo']");// Ends with $("[id*='foo']");// Contains $("[id~='foo']");// Contains word $("[id|='foo']");// Contains prefix $("[id]"); // Has attribute $("[id][class][style]"); // Has all.NET Applications like SharePoint generate some long and ugly markup and IDs id="ctl00$ctl41$g_26ee1140_76aa_4ec0_88 c4_11e7e96480f4$ctl00$ctl02$ctl00$ctl01 $ctl00$ContentTypeChoice" These selector tricks really help

18. jQuery Attributes Once you’ve selected the right DOM element, you can use jQuery to get or set its attributes As of jQuery 1.6, the.prop() method provides a way to explicitly get/set property values, while.attr() gets/sets attributes To retrieve and change DOM properties such as the checked, selected, or disabled state of form elements, use the.prop() method.

19. Example with SharePoint Attributes: Get $("select[title='Region']").val(); $("select[title='Region'] option:selected").text();

20. Example with SharePoint Attributes: Set $("select[title='Region']").val(5); $("select[title='Region'] option:selected").text("boo");

21. Traversing Traversing lets you move around the DOM based on your initial selection This is how you get at elements which are difficult to select directly Ancestry matters in XML / HTML

22. Traversing Down: Find an Element’s Specific Children $("div[id$='QuickLaunchNavigationManager'] li:first").parent().find("li:eq(3) li:first.menu-item-text");

23. Traversal Example from SPServices var possibleValues = $("select[ID$='SelectCandidate'][Title^='" + opt.multiSelectColumn + " ']"); var selectedValues = possibleValues.closest("span").find("select[ID$='SelectResult '][Title^='" + opt.multiSelectColumn + " ']"); SelectCandidateSelectResult

24. Manipulation Once you’ve gotten the right element(s), you can: Manipulate their attributes Set properties Change their contents (innerHTML)

25. Events jQuery’s events enable you to work with all of the standard JavaScript events Used to create behaviors that take effect when the user interacts with the page in the browser, and to further manipulate those behaviors

26. jQuery Events $('.article').click(function(){ // do something }); $('.article').mouseover(function(){ // do something });

27. Effects jQuery gives you a set of effects you can use to change the elements in the page Effects can be: Visual: Change how the user sees existing elements with animations Manipulative: Change where and how elements are shown by moving them around in the DOM

28. jQuery Effects Examples $('.article').hide(); $('.article').slideUp(); $('.article').fadeOut("slow"); $('.article').animate({ "font-size": "24px", "background-color": "red" }, 5000);

29. Putting It Together: Toggling Web Part Visibility var wpTitles = $("h2.ms-webpart-titleText"); // Remove the links on the Web Part Titles wpTitles.find("nobr").unwrap(" "); // Show the pointer on mouseover wpTitles.css("cursor", "pointer"); // Add click behavior that toggles the visibility wpTitles.click(function() { $(this).closest("div.ms-webpart-chrome").find("div:eq(1)").slideToggle(); });

30. Putting It Together: Arranging Checkboxes // Collect all of the choices $(thisFormField).find("tr").each(function() { columnOptions.push($(this).html()); }); out = " "; // Add all of the options to the out string for(i=0; i < columnOptions.length; i++) { out += columnOptions[i]; // If we've already got perRow columnOptions in the row, // close off the row if((i+1) % opt.perRow === 0) { out += " "; } out += " "; // Remove the existing rows... $(thisFormField).find("tr").remove(); //...and append the out string $(thisFormField).find("table").append(out);

31. SharePoint 2013 SOAP Call With SPServices var thisPromise = $().SPServices({ operation: "GetListItems", listName: "Cities" }); thisPromise.done(function() { $(thisPromise.responseXML).SPFilterNode("z:row").each(function() { alert($(this).attr("ows_Title")); }); http://spservices.codeplex.com SOAP (asmx) Web Services are deprecated in SharePoint 2013

32. SharePoint 2013 REST Call $.ajax({ url: "/sites/marca/jquery/_api/web/lists/getbytitle('Cities')/items", type: "GET", headers: { "ACCEPT": "application/json;odata=verbose" }, success: function(data) { var results = data.d.results; for(i=0; i < data.d.results.length; i++) { alert(i + data.d.results[i].Title); } }); How to: Complete basic operations using SharePoint 2013 REST endpoints http://msdn.microsoft.com/en-us/library/jj164022.aspx Understanding and Using the SharePoint 2013 REST Interface http://msdn.microsoft.com/en-us/magazine/dn198245.aspx

33. SharePoint 2013 JSOM Call var siteUrl = "/sites/marca/jQuery"; var clientContext = new SP.ClientContext(siteUrl); var oList = clientContext.get_web().get_lists().getByTitle('Cities'); var camlQuery = new SP.CamlQuery(); camlQuery.set_viewXml(' '); this.collListItem = oList.getItems(camlQuery); clientContext.load(collListItem); clientContext.executeQueryAsync( Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed) ); How to: Complete basic operations using JavaScript library code in SharePoint 2013 http://msdn.microsoft.com/en-us/library/jj163201.aspx function onQuerySucceeded(sender, args) { var listItemInfo = ''; var listItemEnumerator = collListItem.getEnumerator(); while (listItemEnumerator.moveNext()) { var oListItem = listItemEnumerator.get_current(); alert(oListItem.get_item('Title').toString()); } function onQueryFailed(sender, args) { alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace()); }

34. jQueryUI Takes Effects Further $(".article").tabs(); $("input").autocomplete(); $("#infoBox").dialog(); $("table.sortable").sortable(); …and many more

35. jQuery Plugins Abound! If you want to do something sophisticated, look for an existing plugin Due diligence – some of the plugins aren’t written very well Beware of “plugin sprawl”

36. More Useful Tools JSLint http://jslint.com/ Checks your script against accepted standards “Warning: JSLint will hurt your feelings.” JSHint http://jshint.com/ Like JSLint, but a little more forgiving More jQuery aware. JavaScript Compressorator http://compressorrater.thruhere.net/ Minifies script files using multiple methods
