title: jQuery grab a file uploaded with input type='file'
body: <p>I want to grab the file uploaded in a <code>&lt;input type='file'&gt;</code> tag.</p>
  
  <p>When I do $('#inputId').val(), it only grabs the <em>name</em> of the file, not the actual file itself.</p>
  
  <p>I'm trying to follow this: </p>

  <pre><code>function upload(file) {
  
    // file is from a &lt;input&gt; tag or from Drag'n Drop
    // Is the file an image?
  
    if (!file || !file.type.match(/image.*/)) return;
  
    // It is!
    // Let's build a FormData object
  
    var fd = new FormData();
    fd.append("image", file); // Append the file
    fd.append("key", "6528448c258cff474ca9701c5bab6927");
    // Get your own key: http://api.imgur.com/
  
    // Create the XHR (Cross-Domain XHR FTW!!!)
    var xhr = new XMLHttpRequest();
    xhr.open("POST", "http://api.imgur.com/2/upload.json"); // Boooom!
    xhr.onload = function() {
      // Big win!
      // The URL of the image is:
      JSON.parse(xhr.responseText).upload.links.imgur_page;
     }
     // Ok, I don't handle the errors. An exercice for the reader.
     // And now, we send the formdata
     xhr.send(fd);
   }
