为了实现图书翻页的效果我们在网上可以看到很多教程 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

</script> </div> </body> </html> <![endif]--></div> </html> </html> </html> </html> 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 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();

} // 为图书设置宽高 function resizeViewport() { var width = $(window).width(), height = $(window).height(), options = $('.magazine').turn('options'); $('.magazine').removeClass('animated'); $('.magazine-viewport').css({ width: width, height: height }).zoom('resize'); setArrows() ; if ($('.magazine').turn('zoom') == 1) { var bound = calculateBound({ width: options.width, 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({ marginTop: marginTop }); } if (magazineOffset.top < $('.made').height()) $('.made').hide(); else $('.made').show(); $('.magazine').addClass('animated'); } //这里用于返回待预览资源的个数（即书本的页数） function numberOfViews(book) { return book.turn('pages') / 2 + 1; } // 当前页 function getViewNumber(book, page) { return parseInt((page || book.turn('page')) / 2 + 1, 10);

} 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！！！！
