Remove Image Color using jQuery

Last modified on February 24th, 2017 by Vincy.

In this tutorial, we are going to see how to remove image color on hover using jQuery. In the previous tutorial, we have seen how to do fade in/fade out animation using jQuery.

We are handling image background animation by using CSS class selector. Using jQuery we are adding and removing the class on mouse-over and mouse-out events respectively.

HTML Images with jQuery Background Animation

These are the image tags in which we have to apply the jQuery remove color animation.

<img src="fading-photo.png" onMouseOver="show_grey(this)" onMouseOut="show_original(this)" />
<img src="fading-photo1.png" onMouseOver="show_grey(this)" onMouseOut="show_original(this)" />
<img src="fading-photo2.png" onMouseOver="show_grey(this)" onMouseOut="show_original(this)" />

jQuery Function to Remove Image Color

These two jQuery functions are used to add/remove CSS styles to create a black and white effect on images.

<script type="text/javascript">
function show_grey(obj) {
$(obj).addClass("grey-scale");
}
function show_original(obj) {
$(obj).removeClass("grey-scale");
}
</script>

and the style is,

<style>
.grey-scale{-webkit-filter: grayscale(100%); filter: grayscale(100%);}
</style>
