Concealing or revealing an image with jQuery when hovering

I currently have 3 <a> tags within my html, each containing 2 images. Specifically, the greyscale images are the ones that are visible while the colored ones are set to display:none.

I am aiming to achieve a functionality where upon hovering over the greyscale image, it will be hidden and the colored image will appear. Conversely, when not hovering, the colored image should be hidden again. How can I accomplish this using jquery?

<a class="mylink" href="">
    <img src="img/thumbnails/colored-1.jpg" class="color-image"/>
    <img src="img/thumbnails/greyscale-1.jpg" class="greyscale-image"/>
</a>

<a class="mylink" href="">
    <img src="img/thumbnails/colored-2.jpg" class="color-image"/>
    <img src="img/thumbnails/greyscale-2.jpg" class="greyscale-image"/>
</a>

<a class="mylink" href="">
    <img src="img/thumbnails/colored-3.jpg" class="color-image"/>
    <img src="img/thumbnails/greyscale-3.jpg" class="greyscale-image"/>
</a>

.color-image {
    display:none
}

Answer №1

What are the benefits of using jQuery over pure CSS?

One advantage is the ability to change image displays on hover.

a.mylink:hover .color-image,
a.mylink .greyscale-image {
   display: inline;
}

a.mylink .color-image,
a.mylink:hover .greyscale-image {
   display: none;
}

In jQuery, achieving this functionality is simple:

function swap(evt) {
    var isOver = evt.type === "mouseenter";
    link.find(".color-image").toggle(isOver);
    link.find(".greyscale-image").toggle(!isOver);
}

$("a.mylink").hover(swap, swap);

Answer №2

No need for Jquery here. Simply utilize the CSS pseudo-class :hover on the anchor with the class .myLink, as shown below:

.color-image {
    display:none;
}

a.myLink:hover .color-image {
    display: block;
}

a.myLink:hover .greyscale-image {
    display: none;
}

Answer №3

Doing it my way :p

a[class="mylink"]:not(:hover) img[class*="greyscale"],
a[class="mylink"]:hover img[class*="color"] {
    display: inline-block;
}
a[class="mylink"]:not(:hover) img[class*="color"],
a[class="mylink"]:hover img[class*="greyscale"] {
    display: none;
}

Answer №4

One way to achieve this effect is by utilizing CSS :hover selector. By hovering over a grayscale image, you can set the display property to none and vice versa for the colored image. This approach ensures functionality even if JavaScript is turned off. Alternatively, JQuery UI could be a viable option for this task.
