关于随机数应用的小整合

别的不说了   直接上代码

     /*随机数获取集合*/

     var zRandom={

           Capital:function(){

                return new Array('A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z');

           }(),

           //获取low-up的随机数 整数

           between:function(low,up){

                var choices=up-low+1;

                return Math.floor(Math.random()*choices+low);

           },

           //获取随机大写字母

           getCapitalChar:function(){

                return this.Capital[Math.round(Math.random()*25)+0];

           },

           //获取随机小写字母

           getLowerChar:function(){

                return this.Capital[Math.round(Math.random()*25)+0].toLowerCase();

           },

           //两个大写字母加年月日时分秒

           getNormalNum:function(){

                return this.getCapitalChar()+this.getCapitalChar()+new Date().Format("yyyyMMdd-HHmmss")+"00";

           },

           //获取随机数 

           getNumberRandom:function(digit){

                var i=0,res="";

                if(typeof digit=='number'){

                     for(;i<digit;i++){

                           res+=this.between(0,9);

                     }

                }

                return res;

           },

           //获取指定位数随机大写字母

           getCapitalCharRandom:function(digit){

                var i=0,res="";

                if(typeof digit=='number'){

                     for(;i<digit;i++){

                           res+=this.getCapitalChar();

                     }

                }

                return res;

           }

     };
