XMLHttpRequest don't send to another page

[presso]

I use this code to upload files, and this code have a progressbar. The problem with this code is that it never send me to "upload.php" after it have uploaded the file, after it reach 100% on the progressbar. (It's not my code). The code:\[code\]// get form data for POSTing//var vFD = document.getElementById('upload_form').getFormData(); // for FF3var vFD = new FormData(document.getElementById('upload_form')); // create XMLHttpRequest object, adding few event listeners, and POSTing our datavar oXHR = new XMLHttpRequest(); oXHR.upload.addEventListener('progress', uploadProgress, false);oXHR.addEventListener('load', uploadFinish, false);oXHR.addEventListener('error', uploadError, false);oXHR.addEventListener('abort', uploadAbort, false);oXHR.open('POST', 'upload.php');oXHR.send(vFD);\[/code\]The whole script\[code\]// common variablesvar iBytesUploaded = 0;var iBytesTotal = 0;var iPreviousBytesLoaded = 0;var iMaxFilesize = 1048576; // 1MBvar oTimer = 0;var sResultFileSize = '';var uploadingcanceld = "??? ??? ????? ????? ?????";function secondsToTime(secs) { // we will use this function to convert seconds in normal time format var hr = Math.floor(secs / 3600); var min = Math.floor((secs - (hr * 3600))/60); var sec = Math.floor(secs - (hr * 3600) - (min * 60)); if (hr < 10) {hr = "0" + hr; } if (min < 10) {min = "0" + min;} if (sec < 10) {sec = "0" + sec;} if (hr) {hr = "00";} return hr + ':' + min + ':' + sec;};function bytesToSize(bytes) { var sizes = ['Bytes', 'KB', 'MB']; if (bytes == 0) return 'n/a'; var i = parseInt(Math.floor(Math.log(bytes) / Math.log(1024))); return (bytes / Math.pow(1024, i)).toFixed(1) + ' ' + sizes;};function fileSelected() { // hide different warnings document.getElementById('upload_response').style.display = 'none'; document.getElementById('error').style.display = 'none'; document.getElementById('error2').style.display = 'none'; document.getElementById('abort').style.display = 'none'; document.getElementById('warnsize').style.display = 'none'; // get selected file element var oFile = document.getElementById('ufile').files[0]; // filter for image files var rFilter = /^(image\/bmp|image\/gif|image\/jpeg|image\/png|image\/tiff)$/i; if (!
