JS日期与字符串相互转换!!

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;
		 },
