dom-mutation-notifier

Friendly interface for MutationObserver. Eight events are implemented: (element|attribute|text|comment)(Added|Removed)

The constructor takes the same arguments as the observe method of MutationObserver. If no options are provided, childList will be watched by default.

MutationNotifier will only start observing when a valid event listener is added (with on). It will stop observing if all listeners have been removed (with off).

Usage

var MutationNotifier = require("dom-mutation-notifier")

var notifier = new MutationNotifier(document.querySelector("body"))
var addListener = function(element) {}
var rmListener = function(element) {}
notifier.on("elementAdded", addListener)
// Observing starts
notifier.on("elementRemoved", rmListener)
notifier.off("elementAdded", addListener)
notifier.off("elementRemoved", rmListener)
// Observing ends
