SERIOUSLY

Don’t forget to put your card in for the drawing.

You’ll wish you had.

Two sides to every (dev) story

Traditionally, this is how it’s been:

Client-Side Manipulation

• Style changes (though clunky)

• UI goodness (also clunky)• You can push a lot of

buttons…

Server-Side Manipulation

• List item CRUD• Security/Permissions• TRUE POWER!• (but mostly reserved for

Visual Studio)

So why develop client-side?

A few reasons:

• No special permissions required• No required packaging• No solution deployment process

= Quicker changes!

Let’s talk about…

• The role of JavaScript from then to now

• The rise of jQuery

• Tool memos and cool demos

JavaScript in SharePoint(a brief history)

In the beginning, there was… not much.

• SP 1 – wait, there was a SharePoint v1?• WSS 2.0 (SharePoint 2003) – FrontPage

– Web Services!• WSS 3.0 (MOSS 2007) – SP Designer

– Web Services – a few more options– Hack the Content Editor WebPart (CEWP)

JavaScript in SharePoint

Web Services

– (insert mammoth block of code here)

JavaScript in SharePoint

…and then along came jQuery!

– http://jquery.com

– A JavaScript library that abstracts out a ton of basic (and not-so-basic) functions

– Largely affects the markup in the browser

– …BUT has some great built-in AJAX help for calling server resources

JavaScript in SharePoint

Demonstration: Styling, etc. with jQuery

$(document).ready(function() {    var soapEnvelope =        "<soapenv:Envelope xmlns:soapenv='http://schemas.xmlsoap.org/soap/envelope/'> \            <soapenv:Body> \                <GetListCollection xmlns='http://schemas.microsoft.com/sharepoint/soap/'> \                </GetListCollection> \            </soapenv:Body> \        </soapenv:Envelope>";    $.ajax({        url: "http://yoursite/_vti_bin/lists.asmx",        type: "POST",        dataType: "xml",        data: soapEnv,        complete: getListNames,        contentType: "text/xml; charset=\"utf-8\""    });});

function getListNames(xData, status) {    $(xData.responseXML).find("List").each(function() {        $("#data").append("<div>" + $(this).attr("Title") + "</div>");    });}

A lot less code, but still a bit of XML to track. (Do I want to have to know what a “SOAP Envelope” is?)

(Special thanks to Jan Tielens for the code sample)

Web Services and jQuery

The SPServices JavaScript library

• http://spservices.codeplex.com/• Thank you, Marc Anderson (@sympmarc)!• Packaged web service operations for SP• Runs on top of jQuery

A still more excellent way

What’s new in 2010?

All hail the Client-Side Object Model!

• Managed code (VB, C#, anything that compiles for the .NET CLR)

• Silverlight

• JavaScript (ECMAScript)

Managed Code

Pros:• Very powerful.• Easy point of entry for .NET developers

Cons:• Need .NET framework (proper version) on all

target machines• Oh, and Visual Studio. You must compile.

Silverlight

Pros:• It’s cool.• Broader target base -- no .NET install required

Cons:• Still not completely accepted• Users must install a plug-in• Another dev platform to learn (school is boring)

JavaScript

Pros:• Almost universally accepted – mature tech• Platform independent (OOTB browser support)

Cons:• Not all SP CSOM functionality is available• Object types differ (JS is a loosely-typed language)

– Some obscure methods replace

Using JS with the CSOM

All objects are derived from the SharePoint Object Model

What you need:

• SP.js

• The SharePoint default master page (trust me)

• FormDigest element – it’s for your own safety, ma’am.

Using JS with the CSOM

Demonstration: Adding and retrieving list items

The sum of our training

Nothing to see here
