其中具体报错的语句是47行：

1. shijia=shijia.toFixed(2);

另外有一段代码也报同样的错误，具体代码如下：

1. //两个日期之间的日期   
   
2.      //startTime = "2012-3-25";
   
3.     function dayToDay (startTime,endTime){
   
4.         var days = [];
   
5.         var tempStart = startTime.split("-");
   
6.         var dateStart = new Date(tempStart[0],tempStart[1],tempStart[2]);
   
7.           
   
8.         var tempEnt = endTime.split("-");
   
9.         var dateEnt = new Date(tempEnt[0],tempEnt[1],tempEnt[2]);
   
10.           
    
11.         while((dateEnt.getTime()-dateStart.getTime())>=0){
    
12.             var year = dateStart.getFullYear();
    
13.             var month = dateStart.getMonth().toString().length==1?"0"+dateStart.getMonth().toString():dateStart.getMonth();
    
14.             var day = dateStart.getDate().toString().length==1?"0"+dateStart.getDate():dateStart.getDate();
    
15.             days.push(year+"-"+month+"-"+day);
    
16.             dateStart.setDate(dateStart.getDate()+1);
    
17.         }
    
18.         return days;
    
19.     }

复制代码

其中具体报错语句是13行：

1. var month = dateStart.getMonth().toString().length==1?"0"+dateStart.getMonth().toString():dateStart.getMonth();

报错的页面刷新后又恢复正常~没有报错~能够正常执行出结果~但是多次刷新中偶尔又会有几次报错~请问怎么回事？

您好，请问是哪个版呢？
请加我QQ: 2122674861

您好。
把代码改成闭包的方式

已解决，与闭包没有关系。
是不能用Number（）和.toString（）
