Open an entity record in a new window in MS CRM 2013 by Javascript

In CRM 2013 opening an entity record differs from previous versions. While CRM 2011 was all about popup windows CRM 2013 has a flat HTML5 navigation style. But you can still open a record in a popup window.

To open an entity record in a new window pass the following query string parameters.

etn	The logical name of the entity
extraqs	Optional for forms (see Microsoft Dynamics CRM SDK for 2013 documentation)
pagetype	entityRecord
id	The id of the entity
newWindow	true (undocumented)
histKey	a random numeric sequence (undocumented)

The following sample shows the URL and query string parameters to open an account record in a new window:

window.open("https://contoso.crm.dynamics.com/main.aspx?etn=account&extraqs=&histKey=469645694&id={02c2e648-0acd-41f0-9ca8-d8d131e5f47b}&newWindow=true&pagetype=entityrecord","","status=0,resizable=1,width=1000px,height=600px");
