javascript - 在以1600分辨率向前滚动时到达页 footer 分时如何停止固定部分

我已经开发了opencart网站，它的工作正常，但问题是它们在产品列表页中的位置我已将过滤器的位置固定在1980年和1680年的工作状态，但字词过滤器的1600分辨率重叠在enter image description here下的页脚部分屏幕截图上
我也尝试此门户中发布的解决方案
请任何人帮我

$(function() {
    var top = $('#sidebar-sticky').offset().top - parseFloat($('#sidebar-sticky').css('marginTop').replace(/auto/, 0));
    var footTop = $('#main_footer').offset().top - parseFloat($('#main_footer').css('marginTop').replace(/auto/, 0));

    var maxY = footTop - $('#sidebar-sticky').outerHeight();

    $(window).scroll(function(evt) {
        var y = $(this).scrollTop();
        if (y > top) {
            if (y < maxY) {
                $('#sidebar-sticky').addClass('fixed').removeAttr('style');
            } else {
                $('#sidebar-sticky').removeClass('fixed').css({
                    position: 'absolute',
                    top: (maxY - top) + 'px'
                });
            }
        } else {
            $('#sidebar-sticky').removeClass('fixed');
        }
    });
});

#sidebar-sticky{
  position: absolute;
  width: 185px;
}
#sidebar-sticky.fixed{position: fixed;top:70px}
.filter-sticky-container{
  position: relative;
  box-shadow: none;
  border: none;
}
#main_footer{clear: both;}

最佳答案

我得到了上述问题的解决方案
我给了过滤器的高度

#sidebar-stick, .prodListMrgRgt{height:100vh}
