Exploring the world of jQuery animation and background colors with Animate()

I'm currently attempting to implement a basic pulse effect by utilizing JQuery to modify the background color. However, I am facing issues with animating the backgroundColor property.

function show_user(dnid) {
    /* dnid represents the HTML ID of a specific div element. */
    if (! $(dnid).is(':visible')) {
        $(dnid).show()
    }
    $('html, body').animate({scrollTop: $(dnid).offset().top});
    $(dnid).animate({backgroundColor: "#db1a35"}, 1200);
}

A curious observation is that an alternate animation like this one does work:

$(dnid).animate({opacity: "toggle"}, 1200);

However, it's not the desired effect I am seeking.

In addition, the functionality for show() and scrolling within the function work perfectly fine. The only issue lies with the background color animation.

The function mentioned above is triggered by clicking on this link

<a href="#" onclick="javascript:show_user('#9e4cde88b90004ea722e9e129ed83747')">Locate Me</a>

Is there anyone who can assist me in achieving the animated background color?

=========

Thank you to everyone for your assistance. While many responses were similar, here is the solution that worked for me

In my header section

<script src="http://code.jquery.com/color/jquery.color-2.1.2.min.js"></script>

Then directly after the scroll animation in my show_user function.

var bgcolor = $(dnid).css('backgroundColor');
$(dnid).animate({backgroundColor: "#db1a35"}, 2000);
$(dnid).animate({backgroundColor: bgcolor}, 2000);

This results in a quick red "pulse" effect, effectively capturing the user's attention.

Once again, thank you for all the support.

Answer №1

If you want to animate colors with jQuery, you'll need to use the official jQuery.Color plugin.

When animating properties in jQuery, they should be animated to a single numeric value. Some non-numeric properties cannot be animated using basic jQuery functionality (such as background-color), unless you utilize the jQuery.Color() plugin.

Answer №2

When it comes to animating CSS properties with jQuery, you can animate between any numerical value except for colors. However, there are third-party libraries available that allow you to animate color transitions as well. One such library is called jQuery Color. On its official page, you'll find various examples demonstrating how to use it for animating color changes using the .animate() function in jQuery.

HTML

<div></div>

CSS

div {
    background-color: red;
    height: 200px; width: 200px;
    -webkit-animation: pulse 1s ease-in 0 infinite normal both;
    -moz-animation: pulse 1s ease-in 0 infinite normal both;
    -o-animation: pulse 1s ease-in 0 infinite normal both;
    animation: pulse 1s ease-in 0 infinite normal both;
}

@-webkit-keyframes pulse {
    0% { background-color: red; }
    65% { background-color: #7F0093; }
    100% { background-color: blue; }
}
@-moz-keyframes pulse {
    0% { background-color: red; }
    65% { background-color: #7F0093; }
    100% { background-color: blue; }
}
@-ms-keyframes pulse {
    0% { background-color: red; }
    65% { background-color: #7F0093; }
    100% { background-color: blue; }
}
@-o-keyframes pulse {
    0% { background-color: red; }
    65% { background-color: #7F0093; }
    100% { background-color: blue; }
}
@keyframes pulse {
    0% { background-color: red; }
    65% { background-color: #7F0093; }
    100% { background-color: blue; }
}

Answer №4

Before attempting to change the background color a second time, make sure it is already set to the original color. You also mistakenly enclosed the css property 'background-color' in quotes as if I didn't know :)

$(elementId).css({'background-color': "#ffffff"});

$(elementId).animate({'background-color': "#db1a35"}, 1200);

Answer №5

To complete the setup, simply insert the following snippet after your jQuery script:

<script src="https://cdn.jsdelivr.net/jquery.color-animation/1/mainfile"></script>
