Question

What is the best way to create a function that will initiate the download of a particular file based on a specific key provided by the

I need assistance in creating a function for my text box and button setup. Can someone please guide me on how to achieve this?

The user will be provided with a specific alphanumeric key from the website. They must input this key into the text box and then click on the button to access and download a specific file associated with that key. If the entered key matches the one assigned to a file, that file will be downloaded. While there are other files available, only the one paired with the correct key will be downloaded. Any help would be appreciated...

Here is my code:

<center>
        <input class="keyBox" type="text" placeholder="Enter your download key">
        <br><br>
        <div class="text-center">
            <button type="submit" class="btn btn-style btn-primary">Download</button>
        </div>
        </button>
  </center>

Assuming you have a server with an API endpoint that requires the key as a query parameter, this code should work for your needs. Make sure to adjust the URL as necessary for your specific requirements.

<!-- Insert this code after the HTML in your original post -->
<script>
    function onClick(event) {
        // Be sure to change the button's type to "button".
        // This will eliminate the need for this line.
        event.preventDefault()

        const inputElement = document.querySelector('input')
        const filename = inputElement.value

        location.href = `/path/to/${filename}`
    }

    const button = document.querySelector('button')

    button.addEventListener('click', onClick)
</script>

If the API endpoint sends the correct Content-Disposition headers, the browser will attempt to download the file rather than navigating to the URL.

For more precise element selection, consider using id attributes to avoid any confusion with document.querySelector. You can then utilize document.getElementById instead.
