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

You've got a few changes (this assumes you indeed still want to change the image with an ID of IMG, if not use Shadow Wizard's solution).

Remove a.src and replace with a:

<script type="text/javascript">
function changeImage(a) {
    document.getElementById("img").src=a;
}
</script>

Change your onclick attributes to include a string of the new image source instead of a literal:

onclick='changeImage( "1772031_29_b.jpg" );'
