Date nowtime=new Date();//取时间

Date yetime=new Date(nowtime.getTime() - 86400000L);

SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd");

String preTime1=sdf.format(yetime);

String nowTime1=sdf.format(nowtime);

JS代码获取时间

function GetDay()

{

var today=new Date();

var yesterday=new Date();

var yesterday_milliseconds=today.getTime()-1000*60*60*24;

var today_milliseconds=today.getTime();

yesterday.setTime(yesterday_milliseconds);

today.setTime(today_milliseconds);

var strYear=yesterday.getFullYear();

var strDay=yesterday.getDate();

var strMonth=yesterday.getMonth()+1;

var strYear1=today.getFullYear();

var strDay1=today.getDate();

var strMonth1=today.getMonth()+1;

if(strMonth<10)

{

strMonth="0"+strMonth;

}

if(strMonth1<10)

{

strMonth1="0"+strMonth1;

}

secondTime=strYear1+"-"+strMonth1+"-"+strDay1;

firstTime=strYear+"-"+strMonth+"-"+strDay;

//alert(strYesterday+"----"+strToday);

}
