How To Trigger A File Download When Clicking An Html Button Or Javascript

Have you ever wanted to create a webpage where users can download a file simply by clicking a button? Well, you're in luck! In this guide, we'll show you how to trigger a file download when clicking an HTML button or using JavaScript. It's a handy feature that can enhance user experience on your website.

To achieve this functionality, you need to handle the file download process using JavaScript. First, you'll need to create an HTML button that users can click to initiate the download. You can style this button however you like to make it more visually appealing and intuitive for your users.

Next, you'll need to add an event listener to the button to detect when it's clicked. This event listener will then trigger the file download process. Here's a simple example using vanilla JavaScript:

<title>File Download Example</title>


    <button id="downloadButton">Download File</button>

    
        const downloadButton = document.getElementById('downloadButton');
        downloadButton.addEventListener('click', () =&gt; {
            const fileUrl = 'https://www.example.com/file.pdf';
            const fileName = 'example.pdf';

            const a = document.createElement('a');
            a.href = fileUrl;
            a.download = fileName;
            document.body.appendChild(a);
            a.click();
            document.body.removeChild(a);
        });

In this code snippet, we're creating a button with the id `downloadButton`. We then add an event listener that listens for a click on the button. Once clicked, the JavaScript code creates an `` element, sets the file URL and file name, appends it to the document body, triggers a click event on the element, and finally removes it from the document.
