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
