Hello,
I got my configurator app working, running in an iframe, where I change the values in a parent html. Everything is working fine in my prototype.

But in the final parent html done by someone else, the event listeners only work for the first event, as then it was explained to me, the DOM is changing and therefore I would need to “re-register” the event listeners.

How would I do that? Is there an easy solution/workaround?

Many thanks in advance!

Puzzles and JS coding. Fast and expensive.

If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of the meaning at all.

Thanks for the link. I came across theMutationObserver method on my research. But I have no idea how to implement it and was hoping for an easy plug-and-play solution within Verge3D.

Isn’t this a common problem? @yuri Is there a solution, or are you working on a feature for this?

Thanks again!

Nope, in fact it’s a very rare problem. You’re the first and only here.

The mutation observer allows to detect which DOM elements were removed/added. You can filter them by id to re-add event listeners if needed. Without a live example it’s hard to say more.
