时间的加一天、减一天,时间格式化
var todayDate = new Date("2017-08-15"); //初始化时间(时间戳) var maxDate = new Date();
maxDate.setDate(todayDate.getDate()+20); //时间加20天 var maxTime = getNowFormatDateToDay(maxDate); //时间格式化 console.log(maxTime); function getNowFormatDateToDay(date) {//返回时间格式【不精确到时间】(时间戳--》转为 标准时间) var seperator1 = "-"; var seperator2 = ":"; var month = date.getMonth() + 1; var strDate = date.getDate(); if (month >= 1 && month <= 9) { month = "0" + month; } if (strDate >= 0 && strDate <= 9) { strDate = "0" + strDate; } var currentdate = date.getFullYear() + seperator1 + month + seperator1 + strDate; return currentdate; }
