獲取N天前日期

//獲取當前日期
var myDate = new Date();
var nowY = = myDate.getFullYear()ar();
var nowM = = myDate.getMonth()+1()+1;
var nowD = = myDate.getDate();
();
var enddate = nowY+”-“+(nowM<10 ? “0” + nowM : nowM)+”-“+(nowD<10 ? “0”+ nowD : nowD);//當前日期
//獲取三十天前日期
var lw = new Date(myDate - 1000 * 60 * 60 * 24 * 30);//最後一個數字30可改，30天的意思
var lastY = = lw.getFullYear()ar();
var lastM = = lw.getMonth()+1()+1;
var lastD = = lw.getDate();
();
var startdate=lastY+”-“+(lastM<10 ? “0” + lastM : lastM)+”-“+(lastD<10 ? “0”+ lastD : lastD);//三十天之前日期
