div content change event.js

var myElement = document.getElementById('IDoftheDIV');
if(window.addEventListener) {
   // Normal browsers
   myElement.addEventListener('DOMSubtreeModified', contentChanged, false);
} else
   if(window.attachEvent) {
      // IE
      myElement.attachEvent('DOMSubtreeModified', contentChanged);
   }

function contentChanged() {
   // this function will run each time the content of the DIV changes
}

Many thanks for this. Worked like a charm! I am using Stimulus JS in rails. If anybody else doing the same lands here, include this code in connect() function of your controller and use contentChanged as this.contentChanged().

Perfeito, era o que eu estava procurando, muito obrigado!

Thank you so much!
Great code

Thank you. It helped me today!

good, It helped me.

It works...

...and if the the change your listening for involves a list being iterated, you get to watch it work ' + list.length-1 + " times in rapid succession!

Thank you very much work fine and simple and clean

You saved me! Thank you so much!!!!!
