How to download an image with user input name

Question

I'm new to coding, especially JavaScript, so I decided to ask you guys to take a look and maybe help me find a solution. I want to download an image with a name entered by the user. I wish to download and rename a user specified file instead of a predefined URL (as shown in my example). I prefer downloading from the frontend. I tried it in JavaScript but it doesn't work...anyone have any ideas? Try it https://jsfiddle.net/8qj3czvg/...

As someone has already commented, you should have a minimal reproducible example in your application; beyond that, you can try modifying the code in this way (note that additional name validation may be required ).

HTML：

Js：

$(document).ready(function() {
    $('.is-hidden').click(function() {
        domtoimage
            .toPng(document.getElementById('content'), {
                quality: 0.95
            })
            .then(function(dataUrl) {
                let link = document.createElement('a');
                let name = document.getElementById('file-name').value;
                name = name ? name : "placeHolderName"; // checks whether the user has entered a file name
                link.download = `${name}.jpeg`;
                link.href = dataUrl;
                link.click();
            })
    })
})
