SPServices is a jQuery library which abstracts SharePoint’s Web Services and makes them easier to use. It also includes functions which use the various Web Service operations to provide more useful (and cool) capabilities. It works entirely client side and requires no server install.

SPServices can be used with SharePoint 2007, 2010, and 2013, whether on premises or hosted with Office365 or others.
The documentation sections below cover all aspects of SPServices.
These are the low-level functions that allow SPServices to work its magic. Leverage them to interact directly with SharePoint’s web services.
Take the out-of-the-box SharePoint forms to the next level with enhancements like autocomplete, cascading dropdowns and more.
From parsing query string parameters to getting information about the current user, these utility functions are handy tools for building client-side solutions.
SPServices is open source! Help develop it on GitHub.
