导航栏上的导航栏主动滚动

时间：2016-11-27 05:02:30

标签： javascript html css

除了一个问题，我的单页布局工作正常。单击时导航栏链接会根据用户转到或滚动的位置更改颜色。

enter image description here

问题在于，当我点击＆＃34;联系我们＆＃34;链接，导航栏滚动到该位置，但导航栏链接不会改变颜色，如上图所示。它适用于其他所有部分而不是底部，因为该区域不够大。

window.onload=function(){
        // Cache selectors
        var lastId,
                topMenu = $("#top-menu"),
                topMenuHeight = topMenu.outerHeight()+15,
                // All list items
                menuItems = topMenu.find("a"),
                // Anchors corresponding to menu items
                scrollItems = menuItems.map(function(){
                    var item = $($(this).attr("href"));
                    if (item.length) { return item; }
                });

        // Bind click handler to menu items
        // so we can get a fancy scroll animation
        menuItems.click(function(e){
            var href = $(this).attr("href"),
                    offsetTop = href === "#" ? 0 : $(href).offset().top-topMenuHeight+1;
            $('html, body').stop().animate({ 
                    scrollTop: offsetTop
            }, 300);
            e.preventDefault();
        });

        $(window).scroll(function(){
            // Get container scroll position
            var fromTop = $(this).scrollTop()+topMenuHeight;

            // Get id of current scroll item
            var cur = scrollItems.map(function(){
                    if ($(this).offset().top < fromTop)
                        return this;
            });

        // Get the id of the current element
        cur = cur[cur.length-1];
        var id = cur && cur.length ? cur[0].id : "";

您可以将active类的更改移动到单击，此处我已注释掉滚动中发生的更改，将其移动到click事件，还添加了一行以获取ID：< / p> 

window.onload=function(){
        // Cache selectors
        var lastId,
                topMenu = $("#top-menu"),
                topMenuHeight = topMenu.outerHeight()+15,
                // All list items
                menuItems = topMenu.find("a"),
                // Anchors corresponding to menu items
                scrollItems = menuItems.map(function(){
                    var item = $($(this).attr("href"));
                    if (item.length) { return item; }
                });

        // Bind click handler to menu items
        // so we can get a fancy scroll animation
        menuItems.click(function(e){
            var href = $(this).attr("href"),
                    id = href.split('#')[1],
                    offsetTop = href === "#" ? 0 : $(href).offset().top-topMenuHeight+1;
            $('html, body').stop().animate({ 
                    scrollTop: offsetTop
            }, 300);
            e.preventDefault();

            menuItems.parent().removeClass("active").end().filter("[href='#"+id+"']").parent().addClass("active");
        });

        // Bind to scroll
        $(window).scroll(function(){
            // Get container scroll position
            var fromTop = $(this).scrollTop()+topMenuHeight;

            // Get id of current scroll item
            var cur = scrollItems.map(function(){
                    if ($(this).offset().top < fromTop)
                        return this;
            });

        // Get the id of the current element
        cur = cur[cur.length-1];
        var id = cur && cur.length ? cur[0].id : "";

        if (lastId !== id) {
                lastId = id;
            // Set/remove active class
            //menuItems
            //    .parent().removeClass("active")
            //    .end().filter("[href='#"+id+"']").parent().addClass("active");
        }
