實(shí)現(xiàn)整屏上下翻效果：
需加載的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樣式如下：
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代碼如下：
var page=0;//翻屏變量，初始第一屏var shakStaute = 0; //該變量作用是鼠標(biāo)滑輪一直向下或者向上滑動時(shí)出現(xiàn)抖動現(xiàn)象$(function(){ var starttime = 0, endtime = 0; $("body").mousewheel(function(event, delta) { starttime = new Date().getTime(); //記錄翻屏的初始時(shí)間 if (delta < 0&& page>=0 && page<=$(".content .divsame").length-2) { if (shakStaute>=0 &&(starttime == 0 || (endtime - starttime) <= -500)) { //在500ms內(nèi)執(zhí)行一次翻屏 shakStaute=1; page++; renderPage(page,true); //翻屏函數(shù) endtime = new Date().getTime(); //記錄翻屏的結(jié)束時(shí)間 } } 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(){ //點(diǎn)擊小導(dǎo)航也執(zhí)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;}})同時(shí)也是實(shí)時(shí)響應(yīng)的。
再來看一個(gè)例子
注意頭部加載的js，jquery庫，mousewheel.js已經(jīng)實(shí)現(xiàn)的index.js
