I'm working on a small chrome extension for fun, and one thing I need it to be able to do, is to detect when the text inside a div is changed by the webpage itself.The code I'm using is:
var status = document.getElementById("status").innerHTML;
status.onchange = function() {
console.log("CHANGE DETECTED")
And this doesn't seem to work, so what should I use instead?
NOTE: I'd prefer not to use jquery, as I am not even very proficient with javascript at the moment, but if it would be that much simpler/easier, that would be fine.
use this trick

// select the target node
var target = document.querySelector('#some-id');
// create an observer instance
var observer = new MutationObserver(function(mutations) {
mutations.forEach(function(mutation) {
console.log(mutation.type);
});
});
// configuration of the observer:
var config = { attributes: true, childList: true, characterData: true }
// pass in the target node, as well as the observer options
observer.observe(target, config);
// later, you can stop observing
observer.disconnect();
You can't do what you want using change event. On newer browsers, you can use Mutation Observers. On older browsers... well, you ask people to upgrade to newer browsers. :P
