javascript - HTML5 Upload via XHR fails in Chrome -

-

i using xhr upload file works great in ff fails in chrome.

an error thrown says upload failed: 0 means xhr.status comes 0 - i'm not sure means? no other status recorded.

//check if have xhr / file support if (typeof file != "undefined" && typeof (new xmlhttprequest()).upload != "undefined") {     var xhr = new xmlhttprequest();     xhr.upload.onprogress = function(e){         if (e.lengthcomputable){             uploadstarted = true;              var loaded = (e.loaded / e.total) * 100;              showprogress(loaded);         }     };      xhr.onreadystatechange = function(){         if (xhr.readystate == 4){              if (xhr.status == 200){                 uploadcomplete();             } else {                 alert("upload failed: " + xhr.status);             }              console.log("status",xhr.status);         }     };      var formelement = document.getelementbyid("configform");      xhr.open("post", $("#configform").attr('action') , true);     xhr.send(new formdata(formelement)); }

an xhr.status == 0 means there some network error. specs don't how can find out error was.

i suggest log whole xhr structure console (console.log(xhr)). maybe 1 of other fields contains valuable data.

if fails, check error logs of server. maybe wrong on server side.

actionscript 3 - TweenLite does not work with object -

-
i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines.
