mutation-observer.js

// https://developer.mozilla.org/en/docs/Web/API/MutationObserver

// create an observer instance
var observer = new MutationObserver(function(mutations) {
  console.log(mutations);    
});

// configuration of the observer:
var config = { 
  attributes: true, 
  childList: true, 
  characterData: true,
  //subtree: true,
  attributeOldValue: true,
  characterDataOldValue: true,
  //attributeFilter: []
};

// select the target node
var target = document.querySelector('.pump-title-panel');

// pass in the target node, as well as the observer options
observer.observe(target, config);
 
// later, you can stop observing
observer.disconnect();

mutation-summary.js

var handleChanges = function (changes) {
  console.log(changes);
};

var observer = new MutationSummary({
  callback: handleChanges, // required
  //rootNode: myDiv, // optional, defaults to window.document

  oldPreviousSibling: true, // optional, defaults to false
  queries: [
    { all: true },
    // { /* query2 */ }, 
  ]
});

// If/when change report callbacks are no longer desired
// var summaries = observer.disconnect();
// if (summaries) handleChangesUpToHere(summaries);
