I've been looking about for a while now and I cant find a proper answer.

Basically I have a web page that lets the user enter somevalues and download a specific file depending on the values entered. All is working but, I want to enable the user to select where to save the file to, instead of just the browser saving to the default download location.

I am using the follownig to initiate the download.

 /**
        *    Get URL for data file and ensure user wants to download it
        **/
        function getResultDataHandler(result, messages) {
           var dataURL = result.value.url;

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

        /**
        *    Open the download dialog
        **/
        function download(dataURL) {
            console.log("downloading");
            window.open(dataURL, 'Download');
        }

Whether the browser asks the user or not is down to the user's preferences in the browser. You can't bypass those preferences (nor, really, should you — if the user wants to always download files to a specified location, they should be allowed to do that).

What you can do is make sure you're sending the browser as much information as possible to help it make for a good user experience. If you're not already doing so (you probably are), be sure to include a Content-Disposition header in the response to the download request, including a filename field:

Content-Disposition: attachment; filename=foo.csv

But I'm guessing you're already doing that part.
