accessing the SP2013 Site Settings-->Master Page/Navigation settings etc using CSOM (client side object model)

Question

I want to access the SP2013 Site Settings-->Master Page/Navigation settings etc using CSOM (client side object model) using JavaScript or REST service or Webservice which I can call from Javascript.

To be more specific:

I want to access and change the Site Setting--> Navigation (under look and Feel)--> Global and Current Navigation to "Structural Navigation" instead of "Managed Navigation". I want to achieve this using CSOM (Javascript / REST/WebSErvice). I dont want to use server side or managed object model.

Can I get the pointer if such API/objects available for SP 2013?

Thanks nks

I had received similar 'File Not Found' error while trying to set the master page. Try to set your custom master page as:

var ctx = new SP.ClientContext.get_current();
var web = ctx.get_web();

ctx.load(web, 'ServerRelativeUrl');
web.set_masterUrl('/sites/site_collection/_catalogs/masterpage/your_masterpage.master');
web.update();

ctx.executeQueryAsync(
function() {
    window.console && console.log('Master page successfully set to: ' + web.get_customMasterUrl());
},
function (sender, args) { alert("Error" + args.get_message());
});

Note the site relative path: "/sites/site_collection" which is needed if your site is not at the root level.

Haven't actually tried, but using ClientContext you should be able to retrieve current Web and set its CustomMasterUrl (http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.client.web.custommasterurl.aspx) using something like

// Starting with ClientContext, the constructor requires a URL to the 
// server running SharePoint. 
ClientContext context = new ClientContext("http://SiteUrl"); 

// The SharePoint web at the URL.
Web web = context.Web; 

web.CustomMasterUrl = "<path_to_master>"; 

// Note that the web.Update() does not trigger a request to the server
// because the client library until ExecuteQuery() is called. 
web.Update(); 

// Execute the query to server.
context.ExecuteQuery();
