Use Javascript to pull the email from the URL parameter



I want use Javascript to pull the email field (write in the form) from the URL parameter and insert into a pixel conversion before the pixel fires (in my form confirmation dialog). Unfortunately, Unbounce Customer Support doesn’t have an example script to offer as this is custom.

My pixel is :
![](<a href= “Link http//trackeffiliationcom/servlet/effileadid660015881refFIELD_EMAIL”)" alt="" width=“1” height=“1”/>

Currently PHP cannot be used on Unbounce pages because Unbounce doesn’t allow server side scripting.

Can anyone help me ?
Thanks you
