Creating and triggering events

Creating custom events

var event = new Event('build');

// Listen for the event.
elem.addEventListener('build', function (e) { ... }, false);

// Dispatch the event.
elem.dispatchEvent(event);

`MutationObserver`

// Select the node that will be observed for mutations
var targetNode = document.getElementById('some-id');

// Options for the observer (which mutations to observe)
var config = { attributes: true, childList: true, subtree: true };

// Callback function to execute when mutations are observed
var callback = function(mutationsList, observer) {
	for(var mutation of mutationsList) {
		if (mutation.type == 'childList') {
			console.log('A child node has been added or removed.');
		} else if (mutation.type == 'attributes') {
			console.log('The ' + mutation.attributeName + ' attribute was modified.');
		}
	}
};

// Create an observer instance linked to the callback function
var observer = new MutationObserver(callback);

// Start observing the target node for configured mutations
observer.observe(targetNode, config);

// Later, you can stop observing
observer.disconnect();
