It’s a quick tip for you today, it took me longer to test it and then to write the javascript. The problem I had was when I pressed F12 to debug the Javascript on CRM 2013, I could see the name of my javascript file and in the end I had to search for some of the Javascript, which brought up a temporary file where I could put my breakpoint in.

var id =Xrm.Page.data.entity.getId();

var entityName = Xrm.Page.data.entity.getEntityName();

It’s worth getting to know the other functions in Xrm.Page.data.entity

The useful ones are above but there is also getIsDirty, which can be used to see if a field has been modified because only modified fields are sent to the server to be saved. Although that is my CRM 2011 thinking because in the CRM 2013 world fields are sent back to the server every 30 seconds to be saved (unless you have turned autosave off)
