Question

I have a thumbnail image that when you click it changes a larger image on the page. So far I have the Javascript figured out for passing on the .src, .alt, and .title information that makes the picture and tool tip of the picture change.

The large picture has a caption underneath. I was wondering how to also have the caption change when the thumbnail is clicked. I’m assuming I can change it into some sort of Javascript variable but this is my first time using JS so I am still very green.

Answer 1

One way is to have the caption in a container with an ID, and overwrite the innerHTML of that container. i.e.

<div id="myCaption">People of Walmart</div>

<script type=text/javascript>
document.getElementById('myCaption').innerHTML = 'Whoa!';
</script>
