Problem with a class attr

Hello,

I'm trying to execute this command…

sym.$("cible").attr({class:"pancarte"});

… but nothing happens.

Of course, i've tried to apply the pancarte class in my HTML document (to a <p>) and it works.

I also tried with the addClass() method, but nothinh happened.

I'm not able to apply a class to an element in Edge Animate
