title: AJAX and JSP , $getJSON
body: <p>So im really having difficulties in understanding the parameters of $.getJSON(), Im currently in my OJT, and there is a AJAX request parameter that I cant figure out.</p>
  
  <pre><code>$.getJSON(jspGetElems, {elem: $(this).val()}).done(function(result){
          //console.log('result',result);
      });
  </code></pre>
  
  <p>what does the " {elem: $(this).val()} " actually mean?</p>
