Introduction
Here I am going to show you how to determine whether open Form is New Form or its just an existing Record.
alert(Xrm.Page.ui.getFormType())
If its output is 1 then its a New Form and if its output is 2 then it just Existing Record Form with fill up its data means its update Form.Others Form Types are:
1= "create";
2="update"
3="readonly"
4="disabled";
6="bulkedit";
