移动端H5开发 Turn.js实现很棒的翻书效果

作者:陈亚

这篇文章主要为大家详细介绍了Turn.js实现很棒的翻书效果,对Turn.js翻书效果的实现进行总结,感兴趣的小伙伴们可以参考一下

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.js和Swiper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     

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

2、html部分代码

<!DOCTYPE html>
<html>
<head>
 <meta charset="utf-8">
 <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"/>
 <meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no"/>

</div>
<div class="flipbook-viewport" style="display:none;">
 <div class="previousPage"></div>
 <div class="nextPage"></div>
 <div class="return"></div>
 <img class="btnImg" src="./image/btn.gif" style="display: none"/>
 <div class="container">
 <div class="flipbook">
 </div>
 </div>
</div>
<script>
 //自定义仿iphone弹出层
 (function ($) {
 //ios confirm box
 jQuery.fn.confirm = function (title, option, okCall, cancelCall) {
  var defaults = {
  title: null, //what text
  cancelText: '取消', //the cancel btn text
  okText: '确定' //the ok btn text
  };

  if (undefined === option) {
  option = {};
  }
  if ('function' != typeof okCall) {
  okCall = $.noop;
  }
  if ('function' != typeof cancelCall) {
  cancelCall = $.noop;
  }

  var o = $.extend(defaults, option, {title: title, okCall: okCall, cancelCall: cancelCall});

  var $dom = $(this);

  var dom = $('<div class="g-plugin-confirm">');
  var dom1 = $('<div>').appendTo(dom);
  var dom_content = $('<div>').html(o.title).appendTo(dom1);
  var dom_btn = $('<div>').appendTo(dom1);
  var btn_cancel = $('<a href="#"></a>').html(o.cancelText).appendTo(dom_btn);
  var btn_ok = $('<a href="#"></a>').html(o.okText).appendTo(dom_btn);
  btn_cancel.on('click', function (e) {
  o.cancelCall();
  dom.remove();
  e.preventDefault();
  });
  btn_ok.on('click', function (e) {
  o.okCall();
  dom.remove();
  e.preventDefault();
  });

  dom.appendTo($('body'));
  return $dom;
 };
 })(jQuery);

 //上一页
 $(".previousPage").bind("touchend", function () {
 var pageCount = $(".flipbook").turn("pages");//总页数
 var currentPage = $(".flipbook").turn("page");//当前页
 if (currentPage >= 2) {
  $(".flipbook").turn('page', currentPage - 1);
 } else {
 }
 });
 // 下一页
 $(".nextPage").bind("touchend", function () {
 var pageCount = $(".flipbook").turn("pages");//总页数
 var currentPage = $(".flipbook").turn("page");//当前页
 if (currentPage <= pageCount) {
  $(".flipbook").turn('page', currentPage + 1);
 } else {
 }
 });
 //返回到目录页
 $(".return").bind("touchend", function () {
 $(document).confirm('您确定要返回首页吗?', {}, function () {
  $(".flipbook").turn('page', 1); //跳转页数
 }, function () {
 });
 });
</script>
</body>
</html>

3、主要js实现部分

//判断手机类型
window.onload = function () {
 //alert($(window).height());
 var u = navigator.userAgent;
 if (u.indexOf('Android') > -1 || u.indexOf('Linux') > -1) {//安卓手机
 } else if (u.indexOf('iPhone') > -1) {//苹果手机
 //屏蔽ios下上下弹性
 $(window).on('scroll.elasticity', function (e) {
  e.preventDefault();
 }).on('touchmove.elasticity', function (e) {
  e.preventDefault();
 });
 } else if (u.indexOf('Windows Phone') > -1) {//winphone手机
 }
 //预加载
 loading();
}

var date_start;
var date_end;
date_start = getNowFormatDate();

//加载页面

   }
   }
   $(".flipbook").append(tagHtml);
   var w = $(".graph").width();
   $(".flipbook-viewport").show();
  });
  //配置turn.js

    },
    turned: function (e, page, view) {
    console.log(page);
    var total = $(".flipbook").turn("pages");//总页数
    if (page == 1) {

  yepnope({

}

function getNowFormatDate() {
 var date = new Date();
 var seperator1 = "";
 var seperator2 = "";
 var month = date.getMonth() + 1;
 var strDate = date.getDate();
 if (month >= 1 && month <= 9) {
 month = "0" + month;
 }
 if (strDate >= 0 && strDate <= 9) {
 strDate = "0" + strDate;
 }
 var currentdate = date.getFullYear() + seperator1 + month + seperator1 + strDate
 + "" + date.getHours() + seperator2 + date.getMinutes()
 + seperator2 + date.getSeconds();
 return currentdate;
}


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。
