Downloading a Dynamic CSV in Internet Explorer

Question

The following code works in both FireFox and Chrome, but not IE. Essentially, I have a JSON object which gets converted into an array and then to a csv format, when I click

Answer 1

This is my solution in case someone else is looking for a solution. now it works with FF, Chrome , and IE

var csv = JSON2CSV(json_obj);            
var blob = new Blob([csv],{type: "text/csv;charset=utf-8;"});

if (navigator.msSaveBlob) { // IE 10+
navigator.msSaveBlob(blob, "csvname.csv")
    } else {
        var link = document.createElement("a");
        if (link.download !== undefined) { // feature detection
            // Browsers that support HTML5 download attribute
            var url = URL.createObjectURL(blob);
            link.setAttribute("href", url);
            link.setAttribute("download", "csvname.csv");
            link.style = "visibility:hidden";
            document.body.appendChild(link);
            link.click();
            document.body.removeChild(link);
        }           
    }

Now I just need to figure out if there is a way to have the save as screen pop up instead of automatically saving the file. If anybody knows the answer to that please share. For now my users will have to use this functionality.

Thanks all for all the great answers, you guys are awesome.
