三、js代码

//数字滚动;(function($, window, document) { "use strict"; var defaults = { deVal: 0, //传入值 className:'dataNums', //样式名称 digit:'' //默认显示几位数字 }; function rollNumDaq(obj, options){ this.obj = obj; this.options = $.extend(defaults, options); this.init = function(){ this.initHtml(obj,defaults); } } rollNumDaq.prototype = { initHtml: function(obj,options){ var strHtml = '<ul class="' + options.className + ' inrow">'; var valLen = options.digit || (options.deVal + '').length; if(obj.find('.'+options.className).length <= 0){ for(var i = 0; i< valLen; i++){ strHtml += '<li class="dataOne "><div class="dataBoc"><div class="tt" t="38"><span class="num0">0</span> <span class="num1">1</span> <span class="num2">2</span> <span class="num3">3</span> <span class="num4">4</span><span class="num5">5</span> <span class="num6">6</span> <span class="num7">7</span> <span class="num8">8</span> <span class="num9">9</span><span class="num0">0</span> <span class="num1">1</span> <span class="num2">2</span> <span class="num3">3</span> <span class="num4">4</span><span class="num5">5</span> <span class="num6">6</span> <span class="num7">7</span> <span class="num8">8</span> <span class="num9">9</span></div></div></li>'; } strHtml += '</ul>'; obj.html(strHtml); } this.scroNum(options); }, scroNum: function(options){ var number = options.deVal; var $num_item = $('.' + options.className).find('.tt'); var h = $('.dataBoc').height(); $num_item.css('transition','all 2s ease-in-out'); var numberStr = number.toString(); if(numberStr.length <= $num_item.length - 1){ var tempStr = ''; for(var a = 0; a < $num_item.length - numberStr.length; a++){ tempStr += '0'; } numberStr = tempStr + numberStr; } var numberArr = numberStr.split(''); $num_item.each(function(i, item) { setTimeout(function(){ $num_item.eq(i).css('top',-parseInt(numberArr[i])*h - h*10 + 'px'); },i*100) }); } } $.fn.rollNumDaq = function(options){ var $that = this; var rollNumObj = new rollNumDaq($that, options); rollNumObj.init(); };})(jQuery, window, document);web前端开发学习Q-q-u-n： 767-273-102 ，分享学习的方法和需要注意的小细节，不停更新最新的教程和学习方法（详细的前端项目实战教学视频，PDF）
