title: jQuery - Seeing if a "checbox" is checked on entry
body: <p>I'm having trouble understanding why my second code here doesn't work (Ruhetag 2 which has just been edited). As a test to see if my targeting was ok I wrote Ruhetag1, which works find when clicking my checboxes, but I then wrote Ruhetag2 to also have the same function but in addition check to see which checkboxes were already checked on entry. Ruhetag1 works fine, Ruhetag2 isn't reacting at all - it's not giving me an error message either. Can you help me see where this is fallong down. Many thanks.</p>
  
  <p>Ruhetag1</p>
  
  <pre><code>$(".quiet").click(function (e) {
      $(this).parent().find(".optimes input[type=text]").val('');
      $(this).parent().find(".optimes").toggle(); 
  });
  </code></pre>
  
  <p>Ruhetag2</p>
  
  <pre><code>$(function(){   
      $(".quiet").each(function(){
          quiet(this);
      });
      $(".quiet").click(function() {
          quiet(this);
      });
  });
  function quiet() {
      if ($(this).is(':checked')) {
          $(this).parent().find(".optimes input[type=text]").val('');
          $(this).parent().find(".optimes").hide();
      } else {
          $(this).parent().find(".optimes").show();
      }
  }
  </code></pre>
