Following this procedure, you will be able to add S+ links with different functionalities (adding a direct link to a document, site or list or even launching a detailed search within a site).
The process has 2 required steps:
Define the S+ link type you will use.
The URL structure is a different one for each SharePlus link type; therefore, choose the one that is most suitable to your needs.
Enable the S+ link in the index.html file.
The SharePlus link needs to be included in the index.html file.
Locate the place where you want the S+ link and create the link URL structure you need, including resources, parameters, and SharePlus actions.
Include the S+ link. Remember to use splus or spluss (as applicable) instead of HTTP/HTTPS.
(Optional) Test the resulting link.
Make sure the S+ link is working as expected by testing your zip package.
When working with SharePlus links, if the resource URL or the action’s parameters include special characters that are not part of the ASCII character-set, you need to encode them.
For example, “=” must be replaced with “%3d”.
You can encode/decode URL using free tools like http://meyerweb.com/eric/tools/dencoder/.
