Is it possible to change the background color using jQuery?

Question

Is it possible to change the background color using jQuery?

Can you assist me with this:

I have a website and I am looking to modify the bg-coler when hovering over the menu (similar to how it works on the rhcp-website). I attempted using jquery for this, but unfortunately, it did not yield the desired result..

(To clarify, I am not aiming to change the background color of the div container that houses my menu, rather, it should apply to the entire body..--> code)

Appreciate your help!

Here is the code snippet:

<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<link rel="stylesheet" type="text/css" href="style.css">
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js">
</script>

<script type="text/javascript">
    $('.start').hover(function () {
        $('html').css('background-color', '#676767')
    });
</script>

<?php include_once 'template.php' ?>

<title>Maximilian Braun</title>
</head>

<body>
    <div class="start">
        <h1>
            <a href="actor.php" >Schauspieler</a> - <a href="foto.php">Fotograf</a>
        </h1>
    </div>
    <?php echo footer();?>
</body>

Answer №1

To ensure your code is executed after the document is loaded, enclose it within the document ready function,


$(function(){
  $('.begin').hover(function(){$('body').css('background-color','#333')});
});

This is important because JQuery needs the relevant elements to be fully loaded before it can recognize them.

Quick solution with explanation

The reason your code wasn't working is because you were using jQuery before the document had finished loading. It's important to always encapsulate your code within:

$(document).ready(function(){
    //your code here
}

or:

$(function(){
    //your code here
}

Follow what Rajaprabhu suggested:

$(function(){
 $('.start').hover(function(){
   $('html').css('background-color','#676767') } );
});

Adding color animation

On the RHCP website, there is a color change with animation. jQuery alone cannot animate colors. There are two solutions: use a jQuery plugin or employ CSS transitions.

jQuery Plugin

If you include a plugin like jQuery Color, you can utilize:

$(function(){
 $('.start').hover(function(){
   $('html').animate({backgroundColor: '#676767') } );
});

CSS Transitions

Instead of relying on a plugin, opt for CSS animations which handle transitioning between different color values smoothly.

Stick with the original code:

$(function(){
 $('.start').hover(function(){
   $('html').css('background-color','#676767') } );
});

Apply this CSS as well

.start {
   -webkit-transition: background-color 0.3s ease-out; 
           transition: background-color 0.3s ease-out;  
}

Note that IE 9 and below do not support CSS Transitions if you choose this method.

To address your problem, you can use the .ready( handler ) method: All of these three options have the same functionality:

- $( document ).ready( handler )
- $().ready( handler ) (although not recommended)
- $( handler )

$( document ).ready(function( $ ) {

$('.start').hover(function(){$('html').css('background-color','#676767') } );

});
