title: How do I lazy load or partial download of a json file?
body: <p>I have a json file with this structure:</p>
  
  <pre><code>myCallback({
      "title": "data",
      "content": "data",
      "images": [
          {
              "img1": "data",
              "img2": "data"
          }
      ]
  })
  </code></pre>
  
  <p>I would like to know it it is possible to parse the file and extract for example only the title, before it is completely finished downloading. </p>
  
  <p>json files are stored in a remote server, therefor I use jsonp and later parse the full file, but I would like to skip the images (base64 encoded) and only download the first part / title / content.</p>
