javascript - 下拉菜单的问题

Question

我不知道下拉菜单会发生什么，当我移动鼠标时我无法触摸下拉菜单:(我尝试用一​​条线，修改填充，它让我移动所有的线..就是全部关于下面的代码..只是你能为我做什么，非常感谢

(function ($) {
  $(document).ready(function () {
    $('#cssmenu').prepend('<div id="indicatorContainer"><div id="pIndicator"><div id="cIndicator"></div></div></div>');
    var activeElement = $('#cssmenu>ul>li:first');

    $('#cssmenu>ul>li').each(function () {
      if ($(this).hasClass('active')) {
        activeElement = $(this);
      }
    });


    var posLeft = activeElement.position().left;
    var elementWidth = activeElement.width();
    posLeft = posLeft + elementWidth / 2 - 6;
    if (activeElement.hasClass('has-sub')) {
      posLeft -= 6;
    }

    $('#cssmenu #pIndicator').css('left', posLeft);
    var element, leftPos, indicator = $('#cssmenu pIndicator');

    $("#cssmenu>ul>li").hover(function () {
        element = $(this);
        var w = element.width();
        if ($(this).hasClass('has-sub')) {
          leftPos = element.position().left + w / 2 - 12;
        }
        else {
          leftPos = element.position().left + w / 2 - 6;
        }

        $('#cssmenu #pIndicator').css('left', leftPos);
      }
      , function () {
        $('#cssmenu #pIndicator').css('left', posLeft);
      });

    $('#cssmenu>ul').prepend('<li id="menu-button"><a>Menu</a></li>');
    $("#menu-button").click(function () {
      if ($(this).parent().hasClass('open')) {
        $(this).parent().removeClass('open');
      }
      else {
        $(this).parent().addClass('open');
      }
    });
