Our company has restricted any modifications to 2013 SharePoint masterpages. For the most part I have been using layout pages to add scripts however if a site is not a publishing site, I am looking at other methods to perform this function. Even layout pages do not effect a collection but just the pages that are associated.
So my question is how can I add or inject scripts into the masterpage without touching it. Visual Studio method has also been shutdown to us. Any advice would be wonderful. PS: I am a novice coder, more designer.
thanks so much CSM
