Dear Jayakrishna You are breaking rules of html wildly. How do you expect to run the code properly? You gave two different image elements same id. Seriously 🤔 No Offence!

There are two ways: 1: document.querySelector("#test2 #img1"); 2: document.getElementById("img1"); document.getElementById("test2");

Wrong code you gave the images the same class of id. The code will run abnormally

Actually, technically you can use same id for different elements, and It works fine(just as classes). But you should never do that, because in large projects you might get lost, trying to differentiate which id is unique and applied to one specific element (what it's suppose to do), and which is applied to N elements as a class.

You can change before or after it loaded. You have done it right in your second code. If you want on load then your code should be like; window.onload = function() { //your code }();
