Invoice address in One Page Checkout

[Maggie Admin]

Hi all,

 

I am trying to change the behaviour of this checkbox "Please use another address for invoice" but unable to locate the JS codes in the opc-oder.js

 

So my intent is to change this checkbox to be always checked and rename to "Same as Billing". I am able to change this but when it's unchecked it hides the whole <div> of Invoice address. What I wish to do is to enable all the fields instead of hiding the whole invoice address.

 

Where can I find the codes that hide/display the div when the checkbox is ticked/unticked. 

 

Please advise.

 

Regards,

JJ
