Question

Say the javascript has done some DOM manipulation like document.getElementById('id').innerHTML = "text". How do I get the frozen HTML at the very moment?

UPDATE:

I do not mean the particular code above. I mean after any sequence of operation.

Answer 1

Store it beforehand?

var currentHtml = document.getElementById('id').innerHtml;
document.getElementById('id').innerHtml = 'newHtml';

// codes

document.getElementById('id').innerHtml = currentHtml;
