    function getNowFormatDate() {
        var date = new Date(); var seperator1 = "-"; var year = date.getFullYear(); 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 = year + seperator1 + month + seperator1 + strDate; return currentdate; }

 

當前時間減一天

function daysJian(){  
  var date = new Date();//獲取當前時間  
  date.setDate(date.getDate()-1);//設置天數 -1 天  
   var time = date.Format("yyyyMMdd"); }
