<div class="item">A</div>
<div class="item">B</div>
<div class="item">C</div>
<div class="item">D</div>

<div id="test1" class="test"></div>

CSS

.item {
  padding: 10px;
  margin: 10px;
  border: 2px solid #aaa;
}

.item.doing-things {
  border-color: #f00;

JavaScript

var triggered = false,

    $test2 = $('#test2');

$('.item').addClass('doing-things').delay(1000).queue(function(next) {
  // Do some things
  console.log('Things are happening');
  // Check a condition and change variable
  if ( !triggered ) {
    triggered = true;
  }
  // Finished doing things
  $(this).removeClass('doing-things');
  next();
}).queue(function(next) {
  // Check inside queue
  if ( triggered ) { 
    // This will be fired repeatedly in the loop, $('.items').length number of times
    $test1.append('<div>Fired</div>'); 
  }
  next();
});

// Check after queue
if ( triggered ) { 
  // This will fire once, but will be false, because it will fire before the queue finishes (with delays)
  $test2.append('<div>Fired</div>'); 
}
