在点击“下一步”和“上一步”时，任何数量的“里”只移动1次

我有动态的li's(这里是静态的)，但它可以是任何数量的li..在点击下一个和上一个箭头时，它只移动一次，条件是li的总数只能是1或30。我需要的是根据它的总长度来移动li。在目前的情况下，它只移动了一次，我在它里面有很多li .

if ($("ul#localSlider").find('li').is(':hidden')) {
  $('ul#localSlider li:eq(1)').addClass('act');
}
var LocalCurrent = 0;
var localContainer = $('ul#localSlider');
var LocalTotalLi = localContainer.find('li').length;
var localLiWdth = localContainer.find('li').outerWidth();
var localContDiv = $('.local_links .linner').outerWidth();
var LocalPageno = Math.ceil(LocalTotalLi / 6);
localContainer.css('width', LocalPageno * 300 + '%');
var localUlWidth = localContainer.outerWidth();
var localPage = Math.ceil(localUlWidth / localContDiv);
//console.log(localPage);
$('a.localArrow').on('click', function(e) {
  e.preventDefault();
  var $this = $(this);
  var LocalMrgn = 0;
  var Localdir = $this.data('dir');
  LocalCurrent = (Localdir === 'next') ? LocalCurrent + 1 : LocalCurrent - 1;
  if (LocalCurrent <= 0) {
    LocalCurrent = 0;
  }
  if (LocalCurrent >= 2) {
    LocalCurrent = 0;
  }
  var LocalLiWidth = ((300 / LocalTotalLi));
  LocalMrgn = LocalCurrent * localContDiv;
  var LocalUnit;
  if (Localdir && LocalMrgn !== 0) {
    LocalUnit = (Localdir === 'next') ? '-=' : '+=';
  }
  // Animation Here:
  localContainer.animate({
    marginLeft: '-' + LocalMrgn + ''
  }, 500);
});
