Creating a JavaScript Slider

Creating a slider in JavaScript is a fairly simple task. In this example, we will create an HTML page with a slider that can move between two different values. The two values are 0 and 10.

To begin, we need to create the HTML page. This page will have a slider element, which will be a <input type="range"> tag. We will also add a <div> element, which will be used to display the current value of the slider. Here is the HTML page:


<!DOCTYPE html>
<html>
    <head>
        <title>Slider Example</title>
    </head>
    <body>
        <input type="range" min="0" max="10" value="0" />
        <div id="value">0</div>
    </body>
</html>

Next, we need to write the JavaScript code to make the slider work. This code will capture the change event of the slider, and update the value of the <div> element to the current value of the slider. Here is the JavaScript code:


document.querySelector('input[type="range"]').addEventListener('change', function() {
    let sliderValue = this.value;
    document.querySelector('#value').innerHTML = sliderValue;
});

Finally, we need to include the JavaScript code in the HTML page. We will do this by adding a <script> element at the bottom of the <body> element. Here is the complete HTML page:


<!DOCTYPE html>
<html>
    <head>
        <title>Slider Example</title>
    </head>
    <body>
        <input type="range" min="0" max="10" value="0" />
        <div id="value">0</div>
        <script>
            document.querySelector('input[type="range"]').addEventListener('change', function() {
                let sliderValue = this.value;
                document.querySelector('#value').innerHTML = sliderValue;
            });
        </script>
    </body>
</html>

And that's it! We now have a fully-functional slider in JavaScript. It is very easy to create sliders in JavaScript, and they can be used to create interactive and dynamic webpages.
