JS 获取当前时间

var myDate= new Date();

myDate.getYear();        //获取当前年份(2位)
myDate.getFullYear();    //获取完整的年份(4位,1970-????)
myDate.getMonth();       //获取当前月份(0-11,0代表1月)
myDate.getDate();        //获取当前日(1-31)
myDate.getDay();         //获取当前星期X(0-6,0代表星期天)
myDate.getTime();        //获取当前时间(从1970.1.1开始的毫秒数)
myDate.getHours();       //获取当前小时数(0-23)
myDate.getMinutes();     //获取当前分钟数(0-59)
myDate.getSeconds();     //获取当前秒数(0-59)
myDate.getMilliseconds();    //获取当前毫秒数(0-999)
myDate.toLocaleDateString();     //获取当前日期
var mytime=myDate.toLocaleTimeString();     //获取当前时间

myDate.toLocaleString( );        //获取日期与时间

计算时间的上一天 和下一天  这两种方式都可做上一天下一天使用

/下一天
function getNextday(){
var today=“2016-04-15”；
var  t =   new   Date(Date.parse(today.replace(/-/g,   "/")));

var tm=new Date(t.getFullYear(),t.getMonth(),t.getDate()+1);

var m='0'+(tm.getMonth()+1);
var d='0'+tm.getDate()

document.getElementById("lang0").value= tm.getFullYear()+'-'+m.substr(m.length-2)+'-'+d.substr(d.length-2);

}

//前一天
function getYestoday(date){
var date=“2016-04-15”；
var  t =   new   Date(Date.parse(date.replace(/-/g,   "/")));

var yesterday_milliseconds=t.getTime()-1000*60*60*24;
var yesterday = new Date();
yesterday.setTime(yesterday_milliseconds);
var strYear = yesterday.getFullYear();
var strDay = yesterday.getDate();
var strMonth = yesterday.getMonth()+1;
if(strMonth<10)
{strMonth="0"+strMonth;}
if(strDay<10)
{strDay="0"+strDay}
datastr = strYear+"-"+strMonth+"-"+strDay;
document.getElementById("lang0").value=datastr;
}

//当前时间

function nowtimeSelect(){
//alert("11");
var myDate = new Date();
var nowtime1 = myDate.toLocaleDateString();
var year = myDate.getFullYear();    //获取完整的年份(4位,1970-????)
var month = myDate.getMonth();       //获取当前月份(0-11,0代表1月)
month = month+1
if(month>0 && month<10){
month= "0"+month;
}
var day = myDate.getDate();
// alert(year);alert(month);
// alert(day);
// alert(nowtime1.replace("/","-"));
document.getElementById("d414").value =year+"-"+month+"-"+day;
return year+"-"+month+"-"+day;
}
