Question

我有此代码：

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(){
  	
  	});
});

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

Prview

上面的代码创建一个水平菜单。效果很好。菜单上有水平滚动的箭头。

我想将它们变成垂直的，高150像素。怎么做？

我需要将此菜单替换为垂直菜单。菜单中的项目将自上而下。菜单的高度应为150px。怎么做？

Answer 1

这不是实际的，但是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(){
  });
});

row_1 = df2['col_1'][0]
for i in range(len(row_1)):
    df2[i] = row_1[i]

df2.drop('col_1', axis=1, inplace=True)
