如何合并这两个JavaScript函数？

Question

我正在尝试编辑此示例，以便每按一次按钮，facebox仍会打开： Fiddle

我的目标是在上面jsfiddle的结构中的这个Demo工作中使这个弹出窗口效果（称为“reveal.facebox”）。

这是“reveal.facebox”

的完整javascript

(function($) {
  $.facebox = function(data, klass) {
    $.facebox.init()
    $.facebox.loading()
    $.isFunction(data) ? data.call($) : $.facebox.reveal(data, klass)
  }

  $.facebox.settings = {
    loading_image : 'facefiles/loading.gif',
    close_image   : 'facefiles/closelabel.gif',
    image_types   : [ 'png', 'jpg', 'jpeg', 'gif' ],

以下是小提琴的代码：

<div class="bouncyHouse">
  <button type="button">Click Me!</button>

  <div class="bouncer" data-vx='2' data-vy='-3'>
    <span>space</span>
  </div>
  <div class="bouncer" data-vx='-2' data-vy='2'>
    <span>space</span>
  </div>
  <div class="bouncer" data-vx='5' data-vy='2'>
    <span>space</span>
  </div>
</div>

CSS

.bouncyHouse {
  height: 200px;
  width: 150%;
  background-color: black;
  position: relative;
}

.bouncer {
  position: absolute;
  width: 200px;
  color: white;
}

.bouncer:nth-child(2) {
  top: 30px;
  left: 100px;
}

.bouncer:nth-child(3) {
  top: 50px;
  left: 200px;
}

的Javascript

function hitLR(el, bounding) {
  if (el.offsetLeft <= 0 && $(el).data('vx') < 0) {
    //console.log('LEFT');
    $(el).data('vx', -1 * $(el).data('vx'))

  }

    //console.log('TOP');
    $(el).data('vy', -1 * $(el).data('vy'));
  }
  if ((el.offsetTop + el.offsetHeight) >= bounding.offsetHeight) {
    //console.log('BOTTOM');
    $(el).data('vy', -1 * $(el).data('vy'));
  }
}

function mover(el, bounding) {
  hitLR(el, bounding);
  el.style.left = el.offsetLeft + $(el).data('vx') + 'px';
  el.style.top = el.offsetTop + $(el).data('vy') + 'px';

}

function moveIt() {
  $('.bouncer').each(function() {

    mover(this, $('.bouncyHouse')[0]);
  });
};
$htmlBack = $('.bouncer').clone();
moveInterval = setInterval(moveIt, 50);
$('button').on('click', function(){
    console.log(moveInterval);
    if( moveInterval != 0){
        clearInterval(moveInterval);
    $('.bouncer').remove();
    $('.bouncyHouse').eq(0).append($htmlBack);
        $htmlBack = $('.bouncer').clone();
    moveInterval = 0;
  } else {

  }
});
