html5 - Download Binary Data as a File Via Javascript -

-

i'm making ajax call api returns binary data. i'm wondering if possible take binary data , display client in new window? i'm doing right now. problem is, document opens up, blank.

$.ajax({     type: "post",     url: apiurl,     data: xmlrequest,     complete: function(xhr, status) {         var bb = new window.webkitblobbuilder();          // append binary data blob         bb.append(xhr.responsetext);          var bloburl = window.webkiturl.createobjecturl(bb.getblob('application/pdf'));         window.open(bloburl);     } });

any ideas?

okay, figured out. had specify responsetype 'array buffer':

function downloadpdf() {      var xhr = new xmlhttprequest();     xhr.open('post', api_url, true);     xhr.responsetype = 'arraybuffer';      xhr.onload = function(e) {         if (this.status == 200) {             var bb = new window.webkitblobbuilder();             bb.append(this.response); // note: not xhr.responsetext              var blob = bb.getblob('application/pdf');             var bloburl = window.webkiturl.createobjecturl(blob);              window.open(bloburl);         }     };      xhr.send(createrequest()); }
