jquery时间区间获取

Demo:

//获取当前日期
	var myDate = new Date();
	var nowY = myDate.getFullYear();
	var nowM = myDate.getMonth()+1;
	var nowD = myDate.getDate();
	var enddate = nowY+"-"+(nowM<10 ? "0" + nowM : nowM)+"-"+(nowD<10 ? "0"+ nowD : nowD);//当前日期
	//获取三十天前日期
	var lw = new Date(myDate - 1000 * 60 * 60 * 24 * 30);//最后一个数字30可改，30天的意思
	var lastY = lw.getFullYear();
	var lastM = lw.getMonth()+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
	console.info(enddate);
	console.info(startdate);
