Filtering required from object from array of objects
<p>My Structure of data will be like below  </p>

<pre><code> var data = {"Questions" : [
                  {"QID":"Q1","S":"2"},
                  {"QID":"Q2","T":"12"},   
                  {"QID":"Q3","U":"22"}], // Also please suggest me to improve this to make parsing easier
             "Share" : "Yes"
            };
 for(var item in data.Questions)
 {
    if(this.QID == "Q2") // this.QID returns me undefined
    {
        // I want to retrieve the total object i.e
        // {"QID":"Q2","T":"12"} should be returned
    }
 }
</code></pre>

<p>Why does <code>this.QID</code> return me <code>undefined</code>?  How can I retrieve the total object, i.e. <code>{"QID":"Q2","T":"12"}</code>?</p>
