title: javascript find control id
body: <p>I have checkboxes generated with an auto ID</p>
  
  <p>I am using the function below:</p>
  
  <pre><code>getAllSelectedFeeds = function() {
   var val = []; 
   $('input:checkbox:checked').each(function(i) {
     val[i] = $(this).attr('id');
   });
   return val;
  };
  </code></pre>
  
  <p>It checks if any checkboxes are checked but I <strong>only</strong> want it to run for those checkbox controls with "selectedTask" within their autogenerated id such as <code>id="ctl00_m_g_95e8bffc_8200_46ac_887c_98522e26803c_ctl01_ctl02_selectedTask</code></p>
  
  <p>Would this javascript work (using jquery selector) by selecting only those checkboxes checked within a div called 'feedSelector'?
  //Get selected checkboxes IDs</p>
  
  <pre><code>getAllSelectedFeeds = function() {
   var val = []; 
   $('#feedSelector:input:checkbox:checked').each(function(i) {
    val[i] = $(this).attr('id');
   });
   return val;
  };
  </code></pre>
