使用jQuery和jsonp通过键获取选定的JSON值（Vimeo API）

Question

Let's say I have the following json result from an api:

{
  id: 116213129,
  title: "“An Episode,” by Palaxy Tracks",
  description: "Music: Palaxy Tracks<br /> Animation: Luca Tóth and Stephen McNally",
  url: "http://vimeo.com/116213129",
  thumbnail_small: "http://i.vimeocdn.com/video/502490003_100x75.jpg",
  thumbnail_medium: "http://i.vimeocdn.com/video/502490003_200x150.jpg",
  thumbnail_large: "http://i.vimeocdn.com/video/502490003_640.jpg",
  user_id: 14252792,
  width: 1920,
  height: 1080,
  tags: "palaxy tracks, music, an episode, animation, music video"
}

Now let's say I have some jQuery code and I want to only retrieve title and url, but nothing else and do something with them like push them into the value of a textbox on my page or a hidden input. I have seen the $.each method that loops through them, but I don't wt to do that. I just want a few values and I want to get them by their key.

Here is the sample jQuery code that loops through them, I got from jQuery API docs. How can I modify to just get those specific values?

<script>
  $.getJSON("http://vimeo.com/api/v2/video/116213129.json?jsoncallback=?", function (result) {
    var title = result.title;
    var description = result.description;
    $("#popVals").click(function () {
      $('#Video_Title').val(title);
      $('#Video_Description').val(description);
    });
  });
</script>

From the JQuery.getJSON docs :

The success callback is passed the returned data, which is typically a JavaScript object or array as defined by the JSON structure and parsed using the $.parseJSON() method. It is also passed the text status of the response.

In your case its a Javascript object which will be accessible via property access

<script>
  $.getJSON("http://vimeo.com/api/v2/video/116213129.json?jsoncallback=?", function (result) {
    var title = result.title;
    var url = result.url;
    //do something

  });
</script>
