JS日期与字符串相互转换!!

Posted 2020-11-03 侯赛雷

一 日期转字符串

 　　　　　　　　　　dateToString: function(date){  
			var year = date.getFullYear();  
			var month =(date.getMonth() + 1).toString();  
			var day = (date.getDate()).toString();   
			if (month.length == 1) {  
				month = "0" + month;  
			}  
			if (day.length == 1) {  
				day = "0" + day;  
			} 
			var dateTime = year + "-" + month + "-" + day;
			return dateTime;  
		  },

二 字符串转日期

		stringToDate : function(dateStr,separator){ 
			 if(!separator){ 
					separator="-"; 
			 } 
		     var dateArr = dateStr.split(separator); 
		     var year = parseInt(dateArr[0]); 
		     var month; 
		     //处理月份为04这样的情况                          
		     if(dateArr[1].indexOf("0") == 0){ 
		         month = parseInt(dateArr[1].substring(1)); 
		     }else{ 
		          month = parseInt(dateArr[1]); 
		     } 
		     var day = parseInt(dateArr[2]); 
		     var date = new Date(year,month -1,day); 
		     return date; 
		 },
