【问题描述】：

所以我有以下代码（您可以在下面看到）：

JavaScript：

var hidWidth;
var scrollBarWidths = 40;

var widthOfList = function(){
    var itemsWidth = 0;
    $('.list li').each(function(){
        var itemWidth = $(this).outerWidth();
        itemsWidth+=itemWidth;
    });
    return itemsWidth;
};

var widthOfHidden = function(){
    return (($('.wrapper').outerWidth())-widthOfList()-getLeftPosi())-scrollBarWidths;
};

var getLeftPosi = function(){
    return $('.list').position().left;
};

var reAdjust = function(){
    if (($('.wrapper').outerWidth()) < widthOfList()) {
        $('.scroller-right').show();
    }
    else {
        $('.scroller-right').hide();
    }

    if (getLeftPosi()<0){
        $('.scroller-left').show();
    }
    else {
        $('.item').animate({left:"-="+getLeftPosi()+"px"},'slow');
        $('.scroller-left').hide();
    }
}

reAdjust();

$(window).on('resize',function(e)
{  
    reAdjust();
});

$('.scroller-right').click(function()
{
    $('.scroller-left').fadeIn('slow');
    $('.scroller-right').fadeOut('slow');

    $('.list').animate({left:"+="+widthOfHidden()+"px"},'slow',function(){

    });
});

$('.scroller-left').click(function()
{
    $('.scroller-right').fadeIn('slow');
    $('.scroller-left').fadeOut('slow');

    $('.list').animate({left:"-="+getLeftPosi()+"px"},'slow',function(){

    });
});

CSS：

.wrapper {
    position:relative;
    margin:0 auto;
    overflow:hidden;
    padding:5px;
    height:50px;
}

.list {
    position:absolute;
    left:0px;
    top:0px;
    min-width:3000px;
    margin-left:12px;
    margin-top:0px;
}

.list li{
    display:table-cell;
    position:relative;
    text-align:center;
    cursor:grab;
    cursor:-webkit-grab;
    color:#efefef;
    vertical-align:middle;
}

.scroller {
    text-align:center;
    cursor:pointer;
    display:none;
    padding:7px;
    padding-top:11px;
    white-space:no-wrap;
    vertical-align:middle;
    background-color:#fff;
}

.scroller-right{
    float:right;
}

.scroller-left {
    float:left;
}

上面的代码创建了一个运行良好的水平菜单。菜单有水平滚动的箭头。

所以有以下问题 - 怎么做：

我想把它们变成垂直的（-> 150px 高）。
我需要将此菜单替换为垂直菜单。菜单中的项目是从上到下的。菜单的高度为 150 像素。

这不是实际的，但有点接近您想要的输出！：

var hidHeight;
var scrollBarHieghts = 40;
var heightOfList = function(){
  var itemsHeight = 0;
  $('.list li').each(function(){
    var itemHeight = $(this).outerHeight();
    itemsHeight+=itemHeight;
  });
  return itemsHeight;
};
var heightOfHidden = function(){
  return (($('.wrapper').outerHeight())-heightOfList()-getTopPosi())-scrollBarHieghts;
};
var getTopPosi = function(){
  return $('.list').position().top;
};
var reAdjust = function(){
  if (($('.wrapper').outerHeight()) < heightOfList()) {
    $('.scroller-down').show();
  }
  else {
    $('.scroller-down').hide();
  }
  if (getTopPosi()<0) {
    $('.scroller-up').show();
  }
  else {
    $('.item').animate({top:"-="+getTopPosi()+"px"},'slow');
    $('.scroller-up').hide();
  }
}
reAdjust();
$(window).on('resize',function(e){  
  reAdjust();
});
$('.scroller-down').click(function() {
  $('.scroller-up').fadeIn('slow');
  $('.scroller-down').fadeOut('slow');
  $('.list').animate({top:"+="+heightOfHidden()+"px"},'slow',function(){
  });
});
$('.scroller-up').click(function() {
  $('.scroller-down').fadeIn('slow');
  $('.scroller-up').fadeOut('slow');
  $('.list').animate({top:"-="+getTopPosi()+"px"},'slow',function(){
  });
});

谢谢。它不能正常工作。我们有菜单项：tab 1、tab2、tab ... tab5 等。当我看到最后一个 tab5 时，我会单击向下箭头，我没有看到 tab6（下一个选项卡）- 只有 tab12
@traekdjf 尝试全屏。我说它有点接近你想要的！我已经制作了一个起始版本，现在您可以对其进行修改以获得您想要的输出。谢谢:)
