domManip (append/prepend/etc.) RE-evaluates contained scripts

[[email protected]…]

Using append (or another method implemented with domManip) to reposition an in-document element causes its scripts to be re-evaluated.

This is so because domManip passes all contained script elements to evalScript, which evaluates their code and removes the elements. I think it should skip evalScript for elements that are not disconnected or are otherwise known to have already been evaluated.

This is intended behaviour, if you don't need your scripts re-evaluted then i'd recommend separating your presentation from your logic.

If re-evaluation is intended, then why does evalScript remove elements from the DOM?

Also, why is this behavior not documented on the relevant ​Manipulation pages?

This have been bugging users for quite a few years now, at least a config option to turn on/off auto eval on dommanip would be nice.

Refactoring code to separate concerns , unfourtunately might not be an option in some cases. Im left with having to manually move out all the script tags every time I need a larger DOM manip (on content I cannot change).
