Can sp.js be used in 2007?

Question

I'm trying to use the code found at http://msdn.microsoft.com/en-us/library/hh185010(v=office.14).aspx under the section 'Adding a Web Part To A Page With Javascript'. However I cannot get a reference to the file SP.js. Is this found in 2007 or is it only 2010 and on?

Thanks

Answer 1

Try adding this code at the top of the page:

<SharePoint:ScriptLink Name="sp.js" LoadAfterUI="true"
    Localizable="false" runat="server" ID="ScriptLink1" />

SP.js is a part of JavaScript Class Library in SharePoint 2010 Client Object Model (CSOM)

It is not supported to use in previous versions of SharePoint including SharePoint 2007

The CSOM acts as a proxy to connect to a WCF service (Client.svc) for the processing of the request. The Client.svc service is the protocol server responsible for performing all of the operations requested by the client object model. For more details see, for example Working with the ECMAScript Client Object Model (JSOM) in SharePoint 2010–Part 1. This kind of functionality is not available in SharePoint 2007.
