hello there, I have tried to add a widget to my forum , but it load the widget html in a async way, so when I pick a dom in $(document).ready(function(){ $('some dom').dosth()}) ,I cant obtain the dom because the widget html dom haven't load yet.
how can i solve this, very grateful if any help , much thanks

Why you still use async way? waiting the document to be ready is needed.
