On load/unload events for DOM elements using a MutationObserver

usage

var onload = require('on-load')
 
var div = document.createElement('div')
onload(div, function (el) {
  console.log('in the dom')
}, function (el) {
  console.log('out of the dom')
})
 
// Will fire the onload
document.body.appendChild(div)
 
// ... some time later
 
// Will fire the onunload
document.body.removeChild(div)

API

onload(node, onloadFn, onunloadFn, [caller])

Pass a dom node to onload to have a onloadFn function fire when the dom node is added to the document dom and a onunloadFn fire when the dom node is removed from the document dom. Optionally a caller ID can be set to associate the onload/onunload hooks with a particular instance of of a dom node. This is commonly used when 'componentizing' dom nodes.
