Creating a basic jQuery button to switch an element's background color is a breeze

I'm new to this, so I hope this is a straightforward question. I'd like to use the bgtoggle class as a button to switch the background color of the metro class. I know I'm doing something wrong because it's not working as expected. Any help would be greatly appreciated. Thank you!

HTML:

<div class="bgtoggle">
</div>

CSS:

.bgtoggle{
    position: absolute;
    width: 56px;
    height: 43px;
    right:65px;
    top:170px;
    color:#fff;
    font-size: 3em;
    cursor:pointer;
    z-index:9999;
    background-image: url("../images/mthc/bgtoggle.png");
    background-size: 100%;
}

.bgtoggle:hover{
    background-image: url("../images/mthc/bgtoggle2.png");
}

Here's my attempt at jQuery, but it's not working as intended:

$('.bgtoggle').toggle(function () {
    $(".metro").css('background', '#000');
}, function () {
    $(".metro").css('background', '#fff'));
}

Answer №1

I have customized a button using your CSS code (excluding the background image) to change the body's background color, giving it a visually appealing effect. Feel free to adapt this to suit your needs. It's worth mentioning that I've utilized the latest jQuery version, so remember to use jQuery instead of $, although this can be reverted if you prefer an earlier version.

Link to live example

HTML

<div class="bgtoggle"></div>

jQuery

jQuery(document).ready(function(){
    jQuery(".bgtoggle").click(function () {
        jQuery("body").toggleClass("bgcolor--yellow");
    });
});

CSS

body {
    /* Customize the background as desired; I've set it to white */
    background-color: white;
}

.bgcolor--yellow {
    background-color: yellow;
}

I've noticed a few syntax errors on your part (common for beginners) – for instance, not checking if the document is ready. Additionally, I assumed that a button functionality would require an on-click event.

If you prefer achieving this effect through hover, you can use mouseover/mouseout instead:

Alternate method using hover

jQuery(document).ready(function(){
    jQuery(".bgtoggle").mouseover(function () {
        jQuery("body").css("background-color", "yellow");
    });
    jQuery(".bgtoggle").mouseout(function () {
        jQuery("body").css("background-color", "white");
    });
});

If you're wondering how to implement a toggle button using jQuery and have it perform a specific action whenever the toggle event occurs, check out the code snippet provided below.

<html>
<head>
<title>Creating a Toggle Button with jQuery</title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
</head>
<body style="font-family:arial,sans-serif;font-weight:bold;font-size:.9em;">
<center>
<div class="metro" style="width:100;height:100;background-color: rgb(255,  255, 255);">Click to Change Me</div>
<div class="bgtoggle" style="width:100;height:100;cursor:pointer;">Click Here</div>
<script>

$('.bgtoggle').click(function() {
   if ($('.metro').css('background-color')=="rgb(255, 255, 255)"){
       $('.metro').css('background-color', '#000');
   } else if ($('.metro').css('background-color')=="rgb(0, 0, 0)"){
       $('.metro').css('background-color', 'rgb(255, 255, 255)');
   }
});

</script>
</center>
</body>
</html>

Good luck with your coding endeavors!
