View Full Version : img onmouseover/out & a:active ‘if’?

12-21-2006, 12:05 PM
The problem:
-the a:active thumbnail loses opacity with onmouseout.

What works:
-thumbnail img, that also is a link, is defined with 30% opacity
-onmouseover changes this to 100% opacity
-onmouseout returns img to 30% opacity
-clicking thumbnail calls a jscript for swaping out a target image

What’s needed:
-set the thumbnail img to 100% opacity when it has been clicked (a:active) AND retain that opacity until a different thumbnail img is clicked.
-other thumbnails will continue to change opacity settings with onmouseover & -out.

I don’t know scripting and therefore don’t know how to write a script for this. TIA!

Here’s what I have thus far.

<a href="#"><img alt="" src="thumbs/thumb01.gif" class="transON"

<a href="#"><img alt="" src="thumbs/thumb02.gif" class="transON"
onmouseout="this.className='transON'" /></a>

<img src="images/image01.jpg" alt="" id="target" />

No one has any ideas?

It turned out to be a very simple change in CSS.

#thumbsInner a img {opacity: 0.3; -moz-opacity: 0.3; filter: alpha(opacity=30);}
#thumbsInner a:hover img {opacity: 1; -moz-opacity: 1; filter: alpha(opacity=100);}
#thumbsInner a:active img, #thumbsInner a:focus img {opacity: 1; -moz-opacity: 1; filter: alpha(opacity=100);}

<a href="#"><img alt="" src="thumbs/thumb01.gif" onmousedown="MM_swapImage('target','','images/image01.jpg',1)" width="36" height="36" /></a>

The problem being, however, that the first thumbnail is not highlighted on page load, and that the thumbnail loses focus (and thus 100% opacity) when the user clicks anywhere else on the page.
