I need to run JS code after customer successfully submits registration form. Where to put the code?

[Yuriy]

Hi community,

Prestashop v.1.6.0.14

I tried to put the js function in the end of /themes/express/authentication.tpl, and called it with:

<form action="{$link->getPageLink('authentication', true)|escape:'html':'UTF-8'}" method="post" id="account-creation_form" class="std box" onsubmit="theFunction()">

from inside the authentication.tpl, but it runs theFunction() each time REGISTER is pressed, even if form is not validly filled.

More attempts were made... Validation of form is sunk in depts of php. Call theFunction() before redirect from controllers/front/AuthController.php? How? I'm not sure it's worth installing something like V8Js to call js from a php controller.

Maybe put the function when "Registration Successful!" page is shown up, but I can't track the page appearing.

What is the best practice?

Thanks in advance!
