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>';

},

}
var numberArr = numberStr.split('');

}
$.fn.rollNumDaq = function(options){
