1、阅读翻书js
/** * 电子翻书 */ //var width = 1080; //var height = 1680; var width = "10rem"; var height = "15.2rem"; window.onload = function () { //预加载 //loading(18,1); initData(); } function getQueryString(name) { var result = window.location.search.match(new RegExp("[\?\&]" + name + "=([^\&]+)", "i")); if (result == null || result.length < 1) { return ""; } return result[1]; } function initData(){ var book = getQueryString("bookId"); var count = getQueryString("pageCount"); loading_img_url = new Array(); for (var i = 0; i < count; i++) { loading_img_url.push((i+1) + ".png"); } var page = getQueryString("pageNum"); if(!page){ page =1; } loading(book,count,page); } var date_start; var date_end; date_start = getNowFormatDate(); //加载图片 var loading_img_url = []; //加载页面 function loading(book,count,page) { var numbers = 0; var length = loading_img_url.length; //var resUrl = ctxStatic+"/modules/intelligentquery/img/3/"; var resUrl = website + "/lawcase/bookScreenshot?bookId=" + book + "&page="; var jsUrl = ctxStatic+"/modules/front/guide/vertical/"; var bookId = book; var img = new Image(); img.src = resUrl + page; //img.src = resUrl + pageNum + ".png"; img.onerror = function () { numbers += (1 / length) * 100; } img.onload = function () { numbers += (1 / length) * 100; $('.number').html(parseInt(numbers) + "%"); console.log(numbers); if (Math.round(numbers)) { //$('.number').hide(); date_end = getNowFormatDate(); var loading_time = date_end - date_start; //预加载图片 $(function progressbar() { //拼接图片 $('.shade').hide(); var tagHtml = ""; var imgUrl = resUrl + page; //var imgUrl = resUrl + (pageNum) + ".png"; if (pageNum == 1) { tagHtml += "<div id='first'><img src='"+imgUrl+"' /></div>"; } else if (pageNum == length) { tagHtml += "<div id='first'><img src='"+imgUrl+"' /></div>"; } else { tagHtml += "<div><img src='"+imgUrl+"' /></div>"; } $(".flipbook").append(tagHtml); var w = $(".graph").width(); $(".flipbook-viewport").show(); }); //配置turn.js function loadApp() { var w = width; var h = height; $('.flipboox').width(w).height(h); $('.flipbook').turn({ width: w, height: h, elevation: 50, pages: count, display: 'single', gradients: true, autoCenter: true, when: { turning: function (e, page, view) { var total = $(".flipbook").turn("pages");//总页数 $("#currentPage").html(page); $("#pageCount").html("/"+total); if (page == 1) { $(".btnImg").css("display", "none"); $(".mark").css("display", "block"); } else { $(".btnImg").css("display", "block"); $(".mark").css("display", "none"); } if (page == length) { $(".nextPage").css("display", "none"); } else { $(".nextPage").css("display", "block"); } }, turned: function (e, page, view) { var total = $(".flipbook").turn("pages");//总页数 $("#currentPage").html(page); $("#pageCount").html("/"+total); // 判断翻页按钮点击事件以及状态样式 if(page >= total){ $("#next").addClass("btn-invalid").removeAttr('onclick'); }else{ $("#next").removeClass("btn-invalid").attr("onclick","next();"); } if(page == 1){ $("#prev").addClass("btn-invalid").removeAttr('onclick'); $("#indexPage").css("display","none"); }else{ $("#prev").removeClass("btn-invalid").attr("onclick","prev();"); $("#indexPage").css("display","flex"); } }, missing: function (e, pages) { for (var i = 0; i < pages.length; i++) { addPage(pages[i], $(this),bookId); } } } }) var cpage = getQueryString("pageNum"); $(".flipbook").turn('page', cpage); } yepnope({ test: Modernizr.csstransforms, yep: [jsUrl+'js/turn.js'], complete: loadApp }); } } } 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; } //异步加载 function addPage(page, book,bookId) { //var resUrl = ctxStatic+"/modules/intelligentquery/img/3/"; var resUrl = website + "/lawcase/bookScreenshot?bookId=" + bookId + "&page="; var imgUrl = resUrl + (page); var tagHtml = ""; if (page == 1) { tagHtml += "<div id='first'><img src='"+imgUrl+"' /></div>"; } else if (page == length) { tagHtml += "<div id='end'><img src='"+imgUrl+"' /></div>"; } else { tagHtml += "<div><img src='"+imgUrl+"' /></div>"; } // Check if the page is not in the book if (!book.turn('hasPage', page)) { // Create an element for this page var element = $('<div />').html(''); // Add the page book.turn('addPage', element, page); element.html(tagHtml); } }
2、阅读页面
