title: I want get one specific entry from JSON data array and do some modification
body: <p>first I got JSON data via web server just like</p>
  
  <pre><code>$.getJSON(url,function(){
  //my callback function;
  });
  </code></pre>
  
  <p>And now I've got data as following:</p>
  
  <pre><code>{entries:[{title:'foo',id:'UUID',finished:null},{title:'bar',id:'UUID',finished:null},{title:'baz',id:'UUID',finished:null}]}
  </code></pre>
  
  <p>I have to find one specific JSON entry by it's UUID, and after that I need to modify one part for example, make a new json data:</p>
  
  <pre><code>{title:'foo',id:'UUID',finished:true}
  </code></pre>
  
  <p>And send back to server by using</p>
  
  <pre><code>$.post(url, data);
  </code></pre>
  
  <p>I'm totally lost myself with this situation... can anyone help?</p>
