title: How could I parse this json-string?
body: <p>I have a string:</p>
  
  <pre><code>[{"data1":"A"},{"data2":"B"},{"data3":"C"}]
  </code></pre>
  
  <p>I used jQuery to convert this string to json:</p>
  
  <pre><code>test_json = $.parseJSON('[{"data1":"A"},{"data2":"B"},{"data3":"C"}]');
  </code></pre>
  
  <p>I got 3 objects:<br>

  <p>I don't know, how could i get the key and value in this string-json?
  Or the format of string-json is wrong?</p>
