ways to do that. The major methods are to register the file
on a page, to always load the file by using the SharePoint
CustomAction in Module and to load the file on demand by
using the Script on Demand function. This is valid for all
available for that page, and this normally works good.
The problem comes when you are modifying the SharePoint
ribbon using CustomAction and your CustomAction requires

need them all. You might only need them when a page is loaded
or custom actions are executed.
From SharePoint CustomAction in Module you can register

to use the file all over SharePoint.
You can use this code to check condition and load other

You can directly write a block of

There are three steps to load a script on demand: first

At the end of the file that is going to load dynamically
you need to add this line of code:

This function is used to register the file for the Script

SP.SOD.registerSod accepts two arguments, the key for
the file and its SharePoint path. This function registers
the file in the SharePoint memory so that it will be

This SharePoint function accepts three arguments: the
key, the name of the function and the callback function
that is executed after the file has been loaded. The
key should be the same that you used in the method,SP.SOD.registerSOD??.
(You can pass null into the second argument, because

- Do not always load all your files in SharePoint
using CustomAction. It will slow down SharePoint performance.
- You can load files when they are needed by SOD at

that will notify SharePoint that the file is loaded
- Register the file using the function
- Use executeFunc to load the file when needed. This
method executes a callback function once the loading
is done by SharePoint:
SP.SOD.executeFunc(?key???, null, callback);
