与此形成鲜明对比的是另一位巨星——葡萄牙队的c罗。上赛季他虽说有42个进球，但经统计，他的效率不到10%。在这个习惯统计学的社会，c罗的42球从深层分析充满了水分。此外，他的球场道德也属于低劣派，假摔贯穿全场，无处不在，江湖人送外号 "跳水运动员 "，桃色风波更是五花八门，而两者后果呢？看看吧：梅西凭借着08—09赛季带领巴萨取得西甲、国王杯、欧洲冠军联赛三冠王，取得433分，获得金球奖，而c罗只有他的一半不到！
为了实现图书翻页的效果我们在网上可以看到很多好代码教程在这里推荐turn.js网上的turn.js 有api不过是英文的 很多人看起来不方便.关于代码也是奇形怪状在这里我将详细讲解如何使用turn.js实现翻页效果,本篇文章只是讲解 turn.js 如何使用！！！！！！！ 文章最后提供源码下载，结合源码看本文，turn.js更简单！
首先附上个人的文件路径
对于css 和 js文件不需要过多的解释 在这里要注意的是pages文件夹 这里个文件夹下放的是需要预览的图片文件 所以
我们想展示的资源 就放在这个目录下面！！！！！！
接下来 先给大家看一下pages下面的资源名称
可以看到 所有的资源都以数字命名 至于为什么 我们在之后会讲解
接下来 我们开始使将turn.js结合到我们自己的项目中 先附上index.html中的代码

一：在其中值得注意的是：对于js的引用有两处！
1：是开头这里引用了css和js
<link rel="nofollow noopener noreferrer" href="css/magazine.css" rel="external nofollow" rel="external nofollow" rel="stylesheet" type="text/css"> <script type="text/javascript" src="js/jquery.min.1.7.js"></script> <script type="text/javascript" src="js/modernizr.2.5.3.min.js"></script> <script type="text/javascript" src="js/hash.js"></script> <script type="text/javascript" src="js/turn.js"></script> <script type="text/javascript" src="js/turn.html4.min.js"></script> <script type="text/javascript" src="js/zoom.min.js"></script> <script type="text/javascript" src="js/magazine.js"></script>
2：则是index.html的最下方，这里极容易被忽视！！！切记路径不可错误，不然报错！！！！
// Load the HTML4 version if there's not CSS transform
yepnope({
test: Modernizr.csstransforms,
yep: ['js/turn.js'],
nope: ['js/turn.html4.min.js'],
both: ['js/zoom.min.js', 'js/magazine.js', 'css/magazine.css'],
complete: loadApp
});
二：js中的magazine.js 这个js值整个功能实现的支柱 在这里提供了所有的函数。
/*
* Magazine sample
*/
//这里是对前页后页的位置设定
function setArrows() {
/*var width = $(window).width();
//alert("chushihua"+width);
var height = $(window).height();
var bookWidth = $(".magazine").width();
var bookHeight = $(".magazine").height();
//alert("chushihua"+bookWidth);
var arrowSize = $(".next-button").width();
//alert(arrowSize);
alert($(".magazine").offset().left+"\n"+$('.next-button').offset().left);
var LeftArrowLeft = - ( width - bookWidth ) / 4 + 'px' ;
//alert(LeftArrowLeft);
var RightArrowLeft = - ( width - bookWidth+ arrowSize*2) / 4 + 'px' ;
//alert(RightArrowLeft);
//alert(RightArrowLeft);
//alert("zhihou"+bookWidth);
$('.next-button').css( "right",RightArrowLeft );
$('.previous-button').css( "left", LeftArrowLeft );*/
setTimeout(function(){

var magaLeft=$(".magazine").offset().left;
var nextLeft= (width-bookWidth-magaLeft-60)/2;
//alert("width "+width +"\nbookWidth :"+bookWidth +"\nmagaLeft:"+magaLeft+"\nnextLeft:"+nextLeft);
$('.next-button').animate({ "right":nextLeft},300);
$('.previous-button').animate({ "left":nextLeft},300);
},100);
}
//这是用于加载所有的待展示资源

// 这里是识别预览大图还是小图的模式1为大图
function zoomTo(event) {

}
// 判断浏览器
function isChrome() {
return navigator.userAgent.indexOf('Chrome') != -1;
}
function disableControls(page) {
if (page == 1) $('.previous-button').hide();
else $('.previous-button').show();
if (page == $('.magazine').turn('pages')) $('.next-button').hide();
else $('.next-button').show();
}
// 为图书设置宽高
function resizeViewport() {
var width = $(window).width(),

if ($('.magazine').turn('zoom') == 1) {
var bound = calculateBound({

height: options.height,
boundWidth: Math.min(options.width, width),
boundHeight: Math.min(options.height, height)
});
if (bound.width % 2 !== 0) bound.width -= 1;
if (bound.width != $('.magazine').width() || bound.height != $('.magazine').height()) {
$('.magazine').turn('size', bound.width, bound.height);
if ($('.magazine').turn('page') == 1) $('.magazine').turn('peel', 'br');
}
$('.magazine').css({
top: -bound.height / 2,
left: -bound.width / 2
});
}
var magazineOffset = $('.magazine').offset(),
boundH = height - magazineOffset.top - $('.magazine').height(),
marginTop = (boundH - $('.thumbnails > div').height()) / 2;
if (marginTop < 0) {
$('.thumbnails').css({
height: 1
});
} else {
$('.thumbnails').css({
height: boundH
});
$('.thumbnails > div').css({

});
}
if (magazineOffset.top < $('.made').height()) $('.made').hide();

}
//这里用于返回待预览资源的个数（即书本的页数）
function numberOfViews(book) {

}
// 当前页
function getViewNumber(book, page) {
return parseInt((page || book.turn('page')) / 2 + 1, 10);
}
// 记录宽度
function largeMagazineWidth() {

}
function decodeParams(data) {
var parts = data.split('&'),
d,
obj = {};
for (var i = 0; i < parts.length; i++) {
d = parts[i].split('=');
obj[decodeURIComponent(d[0])] = decodeURIComponent(d[1]);
}
return obj;
}
function calculateBound(d) {
var bound = {
width: d.width,
height: d.height
};
if (bound.width > d.boundWidth || bound.height > d.boundHeight) {
var rel = bound.width / bound.height;
if (d.boundWidth / rel > d.boundHeight && d.boundHeight * rel <= d.boundWidth) {
bound.width = Math.round(d.boundHeight * rel);
bound.height = d.boundHeight;
} else {
bound.width = d.boundWidth;
bound.height = Math.round(d.boundWidth / rel);
}
}
return bound;
}
在掌握到这些后 便可使用turn.js
最后 展示一下实现的效果，很流畅！！！！
