How to move an element to left, right, up and down using arrow keys in jQuery

Topic: JavaScript / jQueryPrev|Next

Answer: Use the jQuery keydown() method

You can use the jQuery keydown() method in combination with the animate() method to move an element such as <div> in left, right, up and down direction through pressing the corresponding arrow keys on the keyboard. Let's check out an example to see how this works:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>jQuery Move DIV Element with Arrow Keys</title>
<style>
    .box{
        width: 100px;
        height: 100px;
        position: relative;
        margin: 200px auto 0;
        background: yellowgreen;
    }
</style>
<script src="https://code.jquery.com/jquery-3.5.1.min.js"></script>
<script>
$(document).keydown(function(e){
    switch (e.which){
    case 37:    //left arrow key
        $(".box").finish().animate({
            left: "-=50"
        });
        break;
    case 38:    //up arrow key
        $(".box").finish().animate({
            top: "-=50"
        });
        break;
    case 39:    //right arrow key
        $(".box").finish().animate({
            left: "+=50"
        });
        break;
    case 40:    //bottom arrow key
        $(".box").finish().animate({
            top: "+=50"
        });
        break;
    }
});
</script>
</head>
<body>
    <p><strong>Note:</strong> Click inside the viewport and press the arrow keys to move the box.</p>
    <div class="box"></div>
</body>
</html>
