title: JSON: Get object by attribute
body: <p>i have a json like this:</p>
  
  <pre><code>{
      "page": {
          "id": 220,
          "parentId": 196,
          "property": {
              "1": {
                  "name": "h1",
                  "value": "value i dont need",
              },
              "2": {
                  "name": "tags",
                  "value": "value i dont need",
              },
              "3": {
                  "name": "description",
                  "value": "value i need",
              },
  }
  </code></pre>
  
  <p><strong>The question is:</strong> how can i get "value i need", if the id of property ("3" in my case) is changing dynamicly?
  So, i cannot just use</p>
  
  <pre><code>data.page.property[3].value
  </code></pre>
  
  <p>btw, i'm using jquery.</p>
  
  <p>thanks!</p>
