baseURI not valid in decorateCooked

I’m trying to do this:

How to get topic slug or id from PluginAPI?

PluginAPI newbie here. I have a working script something like: api.decorateCooked($elem => { var iframes = $elem[0].querySelectorAll('iframe'); var uri = $elem[0].baseURI; // modify the iframes in a way that depends on the topic }); I’m using the uri as a key into another database to know how to modify the iframes. However I think this will break if the topic is moved; in any case I would prefer to use the topic id or slug. Is there a way to get those from the PluginAPI?

I think I can use window.location.href instead, but thought I’d point out the inconsistent behavior.

I’m very new at this and don’t understand when I should use decorateCooked and when should I use onPageChange as you suggest, and what other events there might be.
