This week, we're updating our course layouts and descriptions. Presentation and materials always gently change over time, but just occasionally there's a need to make a step change to clear out some of the old and roll in the new. That's now happening - but over a long and complex site it's not instant and you'll see sections of the site changing up to and including 19th September.

Javascript - move cursor over image to change a different image.

Let's imagine that you have an image which is a map on your web page, and as you move over the map you want another image (elsewhere on the page) to change to show the place you're pointing too. Well - it can be done with Javascript, but it's not necessarily easy to find a simple example online ... which is probably why one of my customers asked me how to do it.

Try it out at http://www.wellho.net/demo/terry2.html and see the source code at http://www.wellho.net/resources/ex.php4?item=w602/terry2.html.

If you look at the source code, you'll find a lot of repeated code - not a good idea in the long term, but it will help you see what I have done and how I have done it.

P.S. The original question wasn't about maps and places - it was about a football team and showing pictures of their favourite foods. Yes, it should work for them too!

This is a page archived from The Horse's Mouth at http://www.wellho.net/horse/ - the diary and writings of Graham Ellis. Every attempt was made to provide current information at the time the page was written, but things do move forward in our business - new software releases, price changes, new techniques. Please check back via our main site for current courses, prices, versions, etc - any mention of a price in "The Horse's Mouth" cannot be taken as an offer to supply at that price.
