Open CRM form via JavaScript

Have you been struggling to find out how to open a CRM form from another form or from a custom page?

Here is the solution:

Use window.open("/main.aspx?etn=entityname&pagetype=entityrecord&id=" + recordGUID");

or simply:
 window.open("/main.aspx?etn=entityname&pagetype=entityrecord");

to create a new record.

You can also pass custom parameters using the extraqs parameter and encodeURIComponent. You can find out more from the Crm SDK.

Cheers.
