根据数组向下定位,并在菜单中突出显示部分

data-target 和 data-index

但是,此功能不会突出显示您在菜单中滚动的当前部分。

你可以从我的错误尝试中看出 $(this).addClass('menuFollower-t'); 我试着设置一个类来模拟这个效果,不管它有多不起作用,只在点击时起作用,不会被删除。

功能一

_pdpNavigationScrollTo = function () {
        _pdpLink.on('click', function (e) {
            e.preventDefault();
            var _fixedNavHeight, _target, _target_index, _scrollTopPixels;

            if (!INFORMA.global.device.isDesktop) {

                _target = $(this).data('target');
                _target_index = $(this).data('target-index');

                $('#pdp-sections').slideUp();
                _pdpNavigationHeight = $('#pdp-navigation .nav-pdp-nondesktop').outerHeight();


                if (!_pdpFixed)
                    _pdpSectionsHeight = $('#pdp-sections').height();
                else
                    _pdpSectionsHeight = 0;

                _fixedNavHeight = _navHeightMobile;
                var anchorElementArray = $("[id='" + _target + "']");

                // console.log(anchorElementArray[_target_index]);

                if (anchorElementArray.length >= [_target_index]) {
                    //Fix ben-2018-onscroll

                }
                $('html, body').stop().animate({
                    scrollTop: _scrollTopPixels

                _target_index = $(this).data('target-index');
                _fixedNavHeight = _navHeightMobile;
                var anchorElementArrayDesk = $("[id='" + _target + "']");

                if (anchorElementArrayDesk.length >= [_target_index]) {
                    //Fix ben-2018-onscroll
                    _scrollTopPixels = $(anchorElementArrayDesk[_target_index]).offset().top - (_fixedNavHeight + _pdpNavigationHeight);
                    //End
                     $(this).addClass('menuFollower-t');
                } else {
                    _scrollTopPixels = $("#" + _target).offset().top - (_fixedNavHeight + _pdpNavigationHeight);
                }
                $('html, body').stop().animate({
                    scrollTop: _scrollTopPixels
                }, 1000);
            }

        })
    };

非常感谢您的帮助。

 $('.pdp-item-id').each(function() {
          var _Id = $(this).attr("id");
          for(var i = 0; i < _ArrayOfPdpElements.length; i++) {
