javascript - Is there a way to track all change to an HTML element? -


is there (good) way track changes html element ?

i tried use javascript jquery not work.

$('div.formsubmitbutton input[type="submit"]').change(function(event){                 alert(event);             });

somehow style attribute set on submit button can't find , how done.

you can track changes done dom element using mutationobservers:

// select target node var target = document.queryselector('div.formsubmitbutton input[type="submit"]');  // create observer instance var observer = new mutationobserver(function(mutations) {     mutations.foreach(function(mutation) {         console.log(mutation);     });     });  // configuration of observer: var config = { attributes: true, childlist: true, characterdata: true }  // pass in target node, observer options observer.observe(target, config);

this give mutationrecord object details on changed. more info mutations at: https://hacks.mozilla.org/2012/05/dom-mutationobserver-reacting-to-dom-changes-without-killing-browser-performance/
