Using jQuery to decrease the transparency of an image when the mouse hovers over it

I'm trying to set it up so that when you hover over an image, the opacity decreases by half. I know I must be making a simple mistake here, but I just can't figure out what it is. Any suggestions would be greatly appreciated.

http://jsfiddle.net/bUHVc/1/

   <a href="#" id="right-button"><img class="arrow" src="http://placekitten.com/200/200" alt="right" /></a>

 $('.arrow').hover(
function() {
     $(this).find('img').fadeTo('slow', 0.5);
},
function() {
     $(this).find('img').fadeTo('slow', 1);
 }
);

Answer №1

One elegant approach is to achieve this using basic CSS only, eliminating the need for any additional javascript. By simply adding a class and applying it to all your images, you can accomplish the desired effect. Here's an example:

.arrow:hover {
  opacity: 0.5;
}

If you prefer a smoother transition, you can refer to this resource for customizing the effect.

Answer №2

Ensure that jQuery is included in your code. Consider either eliminating the use of .find() and transferring your classname to the img element, or opting for .children() instead.

For the latest version, refer to this updated fiddle: http://jsfiddle.net/bUHVc/3/

Answer №3

Check out the updated jsfiddle I made for you - http://jsfiddle.net/bUHVc/6/

I noticed a couple of things that needed fixing in your code. Firstly, you forgot to include jquery. Additionally, the line `find("img")` was unnecessary and could be removed. You can achieve the desired effect using the animate() function.

Here is the jQuery code:

$(".arrow").hover(function(){
   $(this).stop().animate({"opacity": "1"}); 
}, function(){
   $(this).stop().animate({"opacity": "0.5"});
});

For the CSS part:

.arrow{
   opacity: 0.5;
}

And finally, the HTML part:

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<a href="#" id="right-button"><img class="arrow" src="http://placekitten.com/200/200" alt="right" /></a>
