Turn.js 实现翻书效果的学习与总结

turn.js

     最近CTO给我分配了一个移动端H5开发的任务,主要功能是需要实现翻书效果,我听过主要需求后,当时是呀!!!接下来自己尝试使用 fullPage.jsSwiper来实现翻书效果,结果效果都不是非常的理想,后来想起自己曾经做过PC版的翻书效果,当时使用的是Turn.js ,查过其相关API后,整个人突然豁然开朗呀,使用Turn.js 完全可以解决当前我接手这个项目的所有需求呀。现在将个人的学习总结如下,若有不正确的地方,欢迎读者给与批评指正! 

     Turn.js的官方网址: http://www.turnjs.com/

     下面是我这个项目上线后的效果:

      

      看过实际项目后,各位看官是不是已经迫不及待的想知道这个项目是如何实现,看官莫急,接下来我就详细的介绍下我的开发过程:

      1、需要引入的脚本文件      

1 <link rel="stylesheet" type="text/css" href="css/basic.css"/>
2 <script type="text/javascript" src="js/jquery.js"></script>
3 <script type="text/javascript" src="js/modernizr.2.5.3.min.js"></script>
4 <script type="text/javascript" src="js/main.js"></script>

     2、html部分代码

     4、最终实现结果

 

注:图片是从网上随便下载的,所以图片的尺寸不规范,导致在手机上浏览时图片不是很完整【不是因为代码写的有问题哦】 !!! 代码打包中没有加入真实项目中的图片,如需看到最佳的效果,建议图片尺寸设计为:750*1217,由于个人的时间和精力有限,我写的这个Demo使用的图片就没有将图片一一修改为750*1217的尺寸。

       5、代码打包 下载
