Change image source with JavaScript

Question

So I\'m new with JavaScript (this is actually my first attempt to make something work) and I\'m having a bit of trouble. I thought I had enough knowledge to make this work,

Answer 1

The problem was that you were using .src without needing it and you also needed to differentiate which img you wanted to change.

function changeImage(a, imgid) {
    document.getElementById(imgid).src=a;
}
