Question

我正在创建一个菜单栏，这时当我将元素颜色变为橙色时，当我将鼠标悬停在菜单栏的第一个和第二个元素上时，下拉div将打开（menuForHeader）。我想滚动时在这个div上，菜单栏的第一个元素的颜色保持橙色。

jquery used
     <script>

    $(document).ready(function(){


     var lastScrollTop = 0
    var currentScrollTop = 0
    $(window).scroll(function (event) { 
        lastScrollTop = currentScrollTop
        currentScrollTop = $(document).scrollTop()
        if (currentScrollTop > lastScrollTop) 
            {
                     $('.menuWrap1').css("background-color","black");

            }
        else
            {
            if(currentScrollTop==0){
                        $('.menuWrap1').css("background","linear-gradient(black, transparent)");
             $('.menuWrap1').css("background","-o-linear-gradient(black, transparent)");
              $('.menuWrap1').css("background","-moz-linear-gradient(black, transparent)");}
    }
    });

      $('#menu2 li:nth-child(2)').mouseover(function(){
         $('.menuWrap1').css("height","163px");



      });
      $('.menuForHeader').mouseover(function(){
           $('.menuWrap1').css("height","163px");


      });
       $('.menuForHeader').mouseout(function(){
           $('.menuWrap1').css("height","60px");

      });

       $('menuForHeader').mouseover(function(){

           $('#menu2 li:nth-child(2) a').css("color","orange");
       });
         $('#menu2 li:nth-child(2)').mouseout(function(){
         $('.menuWrap1').css("height","60px");


      });

     // $('#menu2 li:nth-child(2)').addClass('onHovermenu');

    });

        </script>
         <script type="text/javascript">

    var showStaticMenuBar = false;


    $(window).scroll(function () {


        if (showStaticMenuBar == false) {
            //if I scroll more than 200px, I show it 
            if ($(window).scrollTop() >= 160) {
                //showing the static menu
                $('.menu').addClass('show');

                showStaticMenuBar = true;

            }

        }

        else {
            if ($(window).scrollTop() < 200) {
                $('.menu').removeClass('show');


                showStaticMenuBar = false;
            }

    }

    });

哇，这太难了。我们来试试吧：

var innerHeader = $('.menuForHeader');
var menuWrap1 = $('.menuWrap1');
menuWrap1.mouseover(function() {
    this.css('color', 'orange');
});
innerHeader.mouseover(function() {
    this.css('color', 'orange');
});
innerHeader.mouseout(function() {
    this.css('color', 'green');
});
menuWrap1.mouseout(function() {
    if (innerHeader.style.color === 'green') {
        this.css('color', 'green');
    }
});

使用与jQuery混合的旧式DOM属性。像一个BAWSS！

当下拉菜单打开时，悬停状态不会保持固定状态？
