JS字符串类型转日期然后进行日期比较

1、字符串转日期格式

 1 var stringToDate = function(dateStr,separator){ 
 2     if(!separator){ 
 3         separator="-"; 
 4     } 
 5     var dateArr = dateStr.split(separator); 
 6     var year = parseInt(dateArr[0]); 
 7     var month; 
 8     //处理月份为04这样的情况                          
 9     if(dateArr[1].indexOf("0") == 0){ 
10         month = parseInt(dateArr[1].substring(1)); 
11     }else{ 
12          month = parseInt(dateArr[1]); 
13     } 
14     var day = parseInt(dateArr[2]); 
15     var date = new Date(year,month -1,day); 
16     return date; 
17 }

2. 日期比较

1 var dateFeedBack = stringToDate(gfeedbackDataStore.getRowSet().getRow(0).getItemValue("svfd_FEEBBACK_DATE"));
2     var dateNow = stringToDate(callback_date);
3     var days1 = parseInt(dateFeedBack.getTime()/(1000*60*60*24));
4     var days2 = parseInt(dateNow.getTime()/(1000*60*60*24));
5     if((days2-days1)>7){
6       　　alert("提示：总部确认日期7天内才可退单！");
7       　　return;
8     }
