javaScript+turn.js实现图书翻页效果实例代码

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

<![endif]--></div>

</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();
 //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 width = $(window).width();
 var bookWidth = $(".magazine").width();
 var arrowSize = $(".next-button").width();
 var magaLeft=$(".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
function addPage(page, book) {
 var id, pages = book.turn('pages');
 // Create a new element for this page

 }
}

 // Set the size

 $(this).appendTo(pageElement);
 // Remove the loader indicator
 pageElement.find('.loader').remove();
 });
 // Load the page
 img.attr('src', 'pages/' + page + '.png');//这里就是指向展示资源路径，pages/即之前提及的pages文件夹，根据需要可更换。
 loadRegions(page, pageElement);
}
// 这里是识别预览大图还是小图的模式1为大图
function zoomTo(event) {
 setTimeout(function() {

}
// 加载小图

 img.css({
 width: '100%',
 height: '100%'
 });
 img.unbind('load');
 // Loadnew page
 img.attr('src', 'pages/' + page + '.png');//指向小图路径，同上
}
// 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(),

  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 {

  height: boundH
 });
 $('.thumbnails > div').css({
  marginTop: marginTop
 });
 }

}
//这里用于返回待预览资源的个数（即书本的页数）

}
// 当前页
function getViewNumber(book, page) {

}
// 记录宽度

}
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！！！！
