问题 I have made a tree graph structure and it's working absolutely fine. But now I want to make a small change but unable to make that change.

Ideally I'd like this all to be done in the background rather than having to update the active tab... but not sure if this is possible - maybe for another question perhaps... For now though, my problem is that it will only fetch the DOM of the last URL in the array and ignores

问题 From MDN: The toggle method has an optional second argument that will force the class name to be added or removed based on the truthiness of the second argument. For example, to remove a class (if it exists or not) you can call element.classList.toggle('classToBeRemoved', false); and to add a class (if it exists or not) you can call element.classList.toggle('classToBeAdded', true); To my understanding, the classList is a token list, and lists, unlike arrays, can't have duplicate items.
