Break site permission inheritance in code

Break site permission inheritance in code

Sometimes your want to allow your customer to create a site or a subsite with a simple click. 
And you want that same click to break the permission inheritance of its parent site.

Well, it has taken me some research but I have found a solution to do exactly that in code. 
Just put this code on a Sharepoint page. 
Or include the Sharepoint client object model into your custom page.

Enjoy the power of scripting ! 

  

      
 
function BreakRole()
{
   var copyRoleAssignments = true;
   var clearSubscopes = true;
   var clientContext = new SP.ClientContext.get_current();
   // or if your want to break another sites inheritance
   // var clientContext = new SP.ClientContext("/sites/YourSitecollection/yourSite");
   var oWebsite = clientContext.get_web();
   var $v_0 = new SP.ClientActionInvokeMethod(oWebsite, 'BreakRoleInheritance', [ copyRoleAssignments, clearSubscopes ]);
   clientContext.addQuery($v_0);
   clientContext.executeQueryAsync();
}
