Designated location for downloading specified by the user

I've been searching for a while now and I can't seem to find a satisfactory answer.

Essentially, I have a website where users can input values and download a specific file based on those values. Everything is functional, but I want to give the user the option to choose where to save the file instead of it automatically downloading to the default location on their browser.

This is how I am currently initiating the download process:

 /**
        *    This function gets the data file URL and prompts the user to download it
        **/
        function getResultDataHandler(result, messages) {
           var dataURL = result.value.url;

            var askUser = confirm("Save File?");
            if (askUser == true) {
                download(dataURL);
            }
            else {
                console.log("Download canceled");
            }
            showMessage("", true);
        }

        /**
        *    Opens the download dialog in a new window/tab
        **/
        function download(dataURL) {
            console.log("Downloading...");
            window.open(dataURL, 'Download');
        }

Answer №1

It ultimately depends on the user's browser preferences whether they are prompted when downloading files. It's important to respect these preferences as users should have control over where their downloads go.

To enhance the user experience, ensure you are providing the necessary information to the browser. Make sure to include a Content-Disposition header in the response with a filename field like this:

Content-Disposition: attachment; filename=foo.csv

By incorporating these details into your download request, you can optimize the user experience. Hopefully, you're already implementing this step.
