title: How to get span value jquery
body: <p>I'm trying to get spans text by passing the value of span id to the function like this :</p>
  
  <pre><code>function getDetails(testDetailId){
  alert(jq("#"+testDetailId).text());
  }
  </code></pre>
  
  <p>And I always get null alerted when the click is invoked :</p>
  
  <pre><code>jq("table tr").click(function(){
  var testDetailId = jq(this).attr("id");
  getDetails(testDetailId);
  }); 
  </code></pre>
  
  <p>I use jquery no conflict :</p>
  
  <pre><code>var jq = jQuery.noConflict();
  </code></pre>
  
  <p>some html :</p>
  
  <pre><code>&lt;span id="2"&gt;[{"testId":22,"testPerfReports":[]}]&lt;/span&gt;
  </code></pre>
  
  <p>Any ideas ?</p>
