title: Window closing even on clicking 'cancel' button in confirmation box
body: <p>In my website i conduct an exam in new window &amp; i want that if a user closes this window, he will be redirected to other page if he presses 'ok' on confirmation. But he should stay there if presses 'cancel'. The javascript i'm using is below.</p>

  var validNavigation = false;
  
  function endSession() {
  
   $choice = confirm("You will exit your CSA test. Are you sure you want to close the window?");
  
   if ($choice)
       window.open('Result.aspx', '_blank', 'toolbar=0, scrollbars=1');
  }
  
  function wireUpEvents() {
  
  window.onbeforeunload = function () {
      if (!validNavigation) {
          endSession();
      }
  }
  
  // Attach the event keypress to exclude the F5 refresh
  $(document).bind('keypress', function (e) {
      if (e.keyCode == 116) {
          validNavigation = true;
      }
  });
  
  // Attach the event click for all links in the page
  $("a").bind("click", function () {
      validNavigation = true;
  });
  
  // Attach the event submit for all forms in the page
  $("form").bind("submit", function () {
      validNavigation = true;
  });
  
  // Attach the event click for all inputs in the page
  $("input[type=submit]").bind("click", function () {
      validNavigation = true;
  });
  
  }
  
  $(document).ready(function () {
  wireUpEvents();
  });
  </code></pre>
  
  <p>Here on clicking 'ok' button the 'Result.aspx' window opens successfully, but the problem here is that if user clicks 'cancel' in the confirmation box then also the window is getting closed.
  Please tell me where am i going wrong or any alternative to this.
  Any kind of any help will be appreciated.
  Thanks in advance!!</p>
