Question

how can I get IDs of a html elements that added to page later by using javascript? JS changed the HTML contains after it’s rendered thus selenium can’t get the “just added” html elements.
Thank you.

Answer 1

get the element by Id - 
var element = document.getElementById(StringId);

insert new content -

element.innerHTML = newHTMLText;

append new content -

element.innerHTML += newHTMLText;
