三、js代码

    };

        this.init = function(){
             this.initHtml(obj,defaults);
        }
    }
    rollNumDaq.prototype = {
        initHtml: function(obj,options){
            var strHtml = '
';
            var valLen = options.digit ||  (options.deVal + '').length;
            if(obj.find('.'+options.className).length <= 0){

                }

                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 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){
