Hello,
To add Javascript after an action on the server side, you can use the
PageRenderSupport class.
Actually, this may work for Ajax and non-Ajax request.
To inject this class in your component :
@Environmental
private PageRenderSupport _pageRenderSupport;
Hope it helps.
Christophe.

Objet : Login google-style (with redirect after ajax form refresh)
Hi,
I have a login component that updates itself via a zone. Works
great especially when you enter wrong values (server side verified).
Now, if the form successfully logs in or out, I want to refresh
the current page because it likely looks different because of the
state change.
I tried many things including a <script></script> inside the block
but since its an ajax request, JS is not executed. Or is it and
I am doing something wrong.
Any insides appreciated,
Andreas Pardeike

<div class="kl-login-container">

<div class="kl-login-input">
<t:textfield class="email" t:id="email"
