Dear All
Where I work, we have had for several years, some VSTO customizations that are being used to compose emails and word documents, based of some standard texts saved inside of our SharePoint 2013 installation.
We have moved onto the Office 365 service from Microsoft. We are still having the Office 2013 client installed, but we would like to move our old VSTO customizations to the new Add-in model using HTML and JavaScript. I have tried to move the current Word customization to the new model, but I have run into problems, with how to do the logging into SharePoint from the Add-in. In VSTO, that part is a breeze, but I have been unable to find anything on how to do that from JavaScript.
The trick I am trying to achieve is, is to read a title from a SharePoint list, and populate a HTML textarea, with the Titles read, and another textarea, with the sample text that belongs to that Title, when the user click on the Title, in the first textarea. All the users have logins, to our SharePoint installation, but I cannot find any thing in the Microsoft documentation on how do that using JavaScript.
Any links, suggestions or how-to's you can give me will be much appreciated!
Regards
Tom Madsen
