javaScript+turn.js如何实现图书翻页效果
短信预约 -IT技能 免费直播动态提醒
小编给大家分享一下javaScript+turn.js如何实现图书翻页效果，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！
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

both: ['js/zoom.min.js', 'js/magazine.js', 'css/magazine.css'],
complete: loadApp
});
</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" class="lazy" data-src="js/jquery.min.1.7.js"></script>
<script type="text/javascript" class="lazy" data-src="js/modernizr.2.5.3.min.js"></script>
<script type="text/javascript" class="lazy" data-src="js/hash.js"></script>
<script type="text/javascript" class="lazy" data-src="js/turn.js"></script>
<script type="text/javascript" class="lazy" data-src="js/turn.html4.min.js"></script>
<script type="text/javascript" class="lazy" data-src="js/zoom.min.js"></script>
<script type="text/javascript" class="lazy" data-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。
//这里是对前页后页的位置设定
function setArrows() {
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);

},100);
}
//这是用于加载所有的待展示资源

// Add the page to the flipbook
if (book.turn('addPage', element, page)) {
// Add the initial HTML
// It will contain a loader indicator and a gradient
element.html('<div class="gradient"></div><div class="loader"></div>');
// Load the page
loadPage(page, element);
}
}
function loadPage(page, pageElement) {
// Create an image element
var img = $('<img />');
img.mousedown(function(e) {
e.preventDefault();
});
img.load(function() {
// Set the size
$(this).css({
width: '100%',
height: '100%'
});
// Add the image to the page after loaded
$(this).appendTo(pageElement);
// Remove the loader indicator
pageElement.find('.loader').remove();
});
// Load the page
img.attr('class="lazy" data-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) {

}
// 不需了解

}).attr('region-data', $.param(region.data || ''));

}
function regionClick(event) {
var region = $(event.target);
if (region.hasClass('region')) {

},
100);

};

// 加载大图

}
// 加载小图
function loadSmallPage(page, pageElement) {
var img = pageElement.find('img');
img.css({
width: '100%',
height: '100%'
});
img.unbind('load');
// Loadnew page
img.attr('class="lazy" data-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(),
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);
}
// 记录宽度
function largeMagazineWidth() {
return 2214;
}
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
