onSelector() has been turned into the SelectorObserver class to reduce the performance impact on larger sites:
- its instances can be scoped to any element lower in the DOM tree, not exclusively the entire body and all its children like before
- separate instances can be disabled and reenabled individually on demand
- separate instances can have different MutationObserver options set to further reduce performance impact
- every listener can have a debounce time, so that it doesn't get called too often
- there are now multiple methods to get and remove specific listeners
The SelectorObserver.addListener() method is backwards compatible with the old onSelector() function, so you can just add the class instance in front (for full backwards compat use document.body for the baseElement parameter), then change the old function's name and it should work as before.
For more info and examples, please view the SelectorObserver documentation
