Restrict/Validate the person being visited email address in Sponsor portal Known page

[reachmearun.s]

I am trying to restrict Sponsor to enter mycompany.com domain in the person being visited field and restrict any other personal emails entered in this field. I am currently running ISE 2.2 with Patch14. 

I have found a bug related to it - https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvq23221/?rfs=iqvred  and logged a case with TAC.

Please see the attached picture where in the Sponsor portal is allows me to use any personal emails to be entered in the person being visited field. Is there any working Java script to achieve this function.
