实现整屏上下翻效果:
需加载的js
<script type="text/javascript" src="js/jquery-1.8.3.min.js"></script> <script type="text/javascript" src="js/jquery.mousewheel.js"></script>
css样式如下:
body{padding:0;margin:0; overflow:hidden } ul{list-style:none;} .content{width:100%;height100%;position:relative;top:0;} .div_01,.div_02,.div_03,.div_04{width:100%;margin:0 auto; text-align: center;} .div_01{background: #b20909;} .div_02{background: #0941b2;} .div_03{background: #2db209;} .div_04{background: #b29c09;} .left_fixed{position:fixed;width:15px; height:100px; left:100px;top:200px;z-index:999;} .left_fixed ul li{ background:#000;cursor:pointer;width:15px;height: 15px; border-radius:15px;margin-bottom: 10px; } .left_fixed ul li.active{background:#fff;}
jquery代码如下:
var page=0;//翻屏变量,初始第一屏 var shakStaute = 0; //该变量作用是鼠标滑轮一直向下或者向上滑动时出现抖动现象 $(function(){ var starttime = 0, endtime = 0; $("body").mousewheel(function(event, delta) { starttime = new Date().getTime(); //记录翻屏的初始时间 if (delta < 0&& page>=0 && page<=$(".content .divsame").length-2) { if (shakStaute>=0 &&(starttime == 0 || (endtime - starttime) <= -500)) { //在500ms内执行一次翻屏 shakStaute=1; page++; renderPage(page,true); //翻屏函数 endtime = new Date().getTime(); //记录翻屏的结束时间 } } else if (delta>0 && page>=1 && shakStaute==1 && (starttime == 0 || (endtime - starttime) <= -500)) { page--; renderPage(page,true); endtime = new Date().getTime(); } }); var div_height=$(window).height(); $(".divsame").css({'height':div_height}); $(window).resize(function(){ div_height=$(window).height(); $(".divsame").css({'height':div_height}); $('.content').animate({top:-page*div_height }, 100); }); $(".left_fixed ul li").on("click", function(){ //点击小导航也执行翻屏 var index = $(this).index(); if(index>0){ shakStaute==1; } page = index; renderPage(page, true); $(".left_fixed ul li").removeClass("active"); $(this).addClass("active"); return false; }); function renderPage(pageNumber, isScroll){ if (isScroll){ $('.content').animate({top:-pageNumber*div_height }, 'slow'); $(".left_fixed ul li").removeClass("active"); $(".left_fixed ul li").eq(pageNumber).addClass("active"); } return; } })
同时也是实时响应的。
再来看一个例子
注意头部加载的js,jquery库,mousewheel.js已经实现的index.js

jquery 代码如下(index.js):
var i=0;//翻屏变量,初始第一屏 var s = 0; //该变量作用是鼠标滑轮一直向下或者向上滑动时出现抖动现象 $(function(){ var starttime = 0, endtime = 0; $("body").mousewheel(function(event, delta) { starttime = new Date().getTime(); //记录翻屏的初始时间 if (delta < 0&& i>=0 && i<=2) { if (s>=0&&(starttime == 0 || (endtime - starttime) <= -500)) { //在500ms内执行一次翻屏 s=1; i++; renderPage(i,true); //翻屏函数 endtime = new Date().getTime(); //记录翻屏的结束时间 } } else if (delta > 0&& i>=1&&s==1&& (starttime == 0 || (endtime - starttime) <= -500)) { i--; //console.log(i); renderPage(i,true); endtime = new Date().getTime(); } }); var div_height=$(window).height(); $(".div_01,.div_02,.div_03,.div_04").css({'height':div_height}); $(window).resize(function(){ var div_height=$(window).height(); $(".div_01,.div_02,.div_03,.div_04").css({'height':div_height}); }); function renderPage(pageNumber, isScroll){ if (isScroll){ $('body, html').animate({scrollTop:pageNumber*div_height }, 'slow'); $(".left_fixed ul li").removeClass("active"); $(".left_fixed ul li").eq(pageNumber).addClass("active"); } return; } $(".left_fixed ul li").on("click", function(){ //点击小导航也执行翻屏 var index = $(this).index(); renderPage(index, true); $(".left_fixed ul li").removeClass("active"); $(this).addClass("active"); return false; }); })
jquery.mousewheel实现整屏翻屏效果
