FormData無法在Internet Explorer中工作？

Question

function uploadPhoto(file) { 
    if (!file || !file.type.match(/image.*/)){ 
     if(!file){ 
      postStatus(); 
     } else { 
      return; 
     } 
    } 
    var fd = new FormData(); 
    fd.append("image", file); 
    fd.append("privacy", document.getElementById('privacy-handler').value); 
    var xhr = GetXmlHttpRequest(); 
    xhr.open("POST", "url here"); 
    slideUp('photo-upload'); 
    slideDown('photo-manager-txt'); 
    document.getElementById("photo-manager-txt").innerHTML='<i>Please wait a moment while we process your photo.</i>'; 
    xhr.onload = function() { 
     if(xhr.responseText == '0'){ 
      document.getElementById('photo-manager-txt').innerHTML='<br />Photo upload failed'; 
      slideDown('photo-upload'); 
      return; 
     } else { 
      document.getElementById('photo-txt').value='grab?v=1&file='+xhr.responseText; 
      document.getElementById('photo-manager-txt').innerHTML='Photo uploaded and shared.'; 
      postStatus(); 
     } 
    } 
    xhr.send(fd); 
} 

此功能似乎不工作。當我打電話我使用的功能：

onClick="uploadPhoto(document.getElementById('ID-HERE').files[0]);" 

當我刪除從files[]的0，它ATLEAST運行postStatus();，但它不會上傳照片。我該如何解決這個問題？

IE中的XHR在IE10之前不支持FormData。您可以安裝Windows 8 Customer Preview來嘗試。
