(Javascript) Super simple slider/carousel/slideshow

By | August 14, 2015

Here’s how you can make a super simple slideshow that changes slides on a timer interval. You could easily edit it so any other event, like a mouse click, will trigger the slide() function.

You can see it in action HERE

HTML

<div class="slider">

    <div class="slide red">
        <p>THIS IS SLIDE 1</p>
    </div>

    <div class="slide blue">
        <p>THIS IS SLIDE 2</p>
    </div>

    <div class="slide green">
        <p>THIS IS SLIDE 3</p>
    </div>

</div>

CSS

.slider {
    width: 500px;
    height: 300px;
    margin: 0 auto;

    /* DON'T CHANGE THESE */
    position: relative;
    overflow: hidden;
}

.slide {
    /* DON'T CHANGE THESE */
    position: absolute;
    width: 100%;
    height: 100%;
}

/** ONLY FOR STYLING THE EXAMPLE SLIDES */
.slide p {
    color: #FFF;
    text-align: center;
}

.red {
    background: red;
}

.blue {
    background: blue;
}

.green {
    background: green;
}

jQuery

<script src="http://code.jquery.com/jquery-1.11.3.min.js"></script>
<script src="http://code.jquery.com/jquery-migrate-1.2.1.min.js"></script>
<script>
    // Configurable values
    slider = $('.slider'); // Slider element
    slideDuration = 3000; // Duration of each slide in milliseconds
    slideSpeed = 1000; // Speed of slide animation in milliseconds (must be equal of less than slideDuration)


    width = slider.width();
    slider.children().hide().css({left: width});
    slider.children(':first').show().css({left: 0});

    // Slide in from the left
    $.fn.slideIn = function () {
        $(this).show().animate({
            left: "-=" + width
        }, slideSpeed / 2);
    }

    // Slide out to the left
    $.fn.slideOut = function () {
        $(this).animate({
            left: "-=" + width
        }, slideSpeed / 2, function () {
            $(this).hide().css({left: width});
        });
    }

    // Main slide function
    function slide() {
        currentSlide = slider.find('div:visible:first');
        nextSlide = (!slider.children(":last").is(":visible")) ? currentSlide.next() : slider.children(':first');

        currentSlide.slideOut();
        nextSlide.slideIn();
    }

    // Timer function
    window.setInterval(function () {
        slide();
    }, slideDuration);
</script>

And of course you could make this dynamic by spitting out the slides from a database… for example like this:

<div class="slider">

<?php foreach ($slides as $slide) { ?>

    <div class="slide">
        <p><?php $slide['content'] ?></p>
    </div>

<?php } ?>

</div>

    Hello! It seems to be a great and simple trick, but i’m trying to set in on an LARAVEL website, and it doesn’t
    work. The green slide shows up, but dont jump to another… Any idea?
