FileSaver saveAs not working in IE11

Question

I'm currently using the jszip, jszip-utils, and FileSaver to zip and download several PDFs.

self.createZip = function () {
    var docs = self.list.filteredItems();
    var zip = new JSZip();
    var count = 0;
    var zipFilename = "zipFilename.zip";

    docs.forEach(function (item) {
        var filename = item.formDesc() + "_" + item.id() + ".pdf";
        // loading a file and add it in a zip file
        JSZipUtils.getBinaryContent('../career/document/StreamFile/?path=' + item.fileName(), function (err, data) {
            if (err) {
                throw err; // or handle the error
            }
            zip.file(filename, data, { binary: true });
            count++;
            if (count == docs.length) {
                zip.generateAsync({ type: 'blob' }).then(function (content) {
                     try {
                             saveAs(content, zipFilename);
                        } catch (e) {
                            console.log(e);
                        }                   
                });                
            }
        });
    });

This function currently works on all latest browsers except IE11. In IE11 is gets all the files, but Hangs on saveAs.

Try the following after your SaveAs statement to clear the buffer

content = null;
