css样式表
*{margin:0;padding: 0;} ul li{ list-style:none; } .header,.footer{ width: 100%; height: 400px; background: #ccc; text-align: center; color: #000; line-height: 400px; font-size: 70px; } .mainbox{ width: 100%; height: 600px; text-align: center; color: #a55; line-height: 600px; font-size: 70px; font-weight: bold; margin: 0 auto; } ul{ position: fixed; width: 30px; border: 1px solid purple; right: 8%; top: 200px; } ul{ display: none; } ul li{ width: 30px; height: 30px; text-align: center; line-height:30px; overflow: hidden; background: #fff; } li.btn{ border-bottom:1px solid purple; font-size: 12px; } .last{ font-size: 16px; font-weight: bold; } span{ display: block; width: 30px; height: 30px; } .second{ background:purple; color:#fff; } .focus{ display: none; } .active{ display: none; }
jQuery特效js
$(function(){ $(".btn").hover(function(){ $(this).find(".first").addClass("focus") },function(){ $(this).find(".first").removeClass("focus") }) $(document).scroll(function(){ var tops=$(this).scrollTop(); if(tops>=200){ $("ul").show(700) }else{ $("ul").hide(700) } $(".mainbox").each(function(i,o){ var bTop=$(o).offset().top; if(tops>=bTop){ $(".first").removeClass("active").eq(i).addClass("active") } }) }) $(".btn").click(function(){ var index=$(this).index(); var topss=$(".mainbox").eq(index).offset().top; $("html,body").stop().animate({scrollTop:topss},800) }) $(".last").click(function(){ $("html,body").stop().animate({scrollTop:0},800) }) })
最后在引入本地jQuery文件或者外部引用
