I have a sandbox solution (not visual) that contain only js files. Now I would like to add some functionality like getting List Items, Get List Guid by name and etc.
What is the best way to do it?
I tried to use $().SPServices, but I get Object doesn't support property or method 'SPServices' error.
The necessary js file is added to the aspx.
Does SandBox allow to run SPServices?
Maybe there is a way to add code behind that I can call from js? What kind of class it should be?
Thanks
