javascript in master page to be run only when a document library is opened

Question

I already found a similar post here:

register-javascript-for-document-library

But instead of adding a content/script editor to every document library, as suggested, I'd prefer to add my code to the system master page and have it triggered only when a document library gets opened. Does any one have a solution for this? The code I developed is working great when I put it in a script editor, now how can I make it run from the master page only on document libraries?

Answer 1

you maybe get Doc. library by checking the url if it contains Forms/AllItems.aspx and then execute your code

Answer 2

Ok, I solved my problem. Here's my solution:

        if ( ctx != null && ctx.listBaseType == 1) {
            //YOUR CODE HERE
        }

This way the code will be executed only if the Sharepoint ctx variable is loaded and the library you open is a Document Library (that means that listBaseType == 1).
