JS 取當(dāng)前日期、時間的代碼 收藏
1.JS 取當(dāng)前日期、時間的代碼？
--------------------------------------------------------------------------------
view plaincopy to clipboardprint?
<SCRIPT LANGUAGE="JavaScript">
<!--
var myDate = new Date();
myDate.getYear(); //獲取當(dāng)前年份(2位)
myDate.getFullYear(); //獲取完整的年份(4位,1970-????)
myDate.getMonth(); //獲取當(dāng)前月份(0-11,0代表1月)
myDate.getDate(); //獲取當(dāng)前日(1-31)
myDate.getDay(); //獲取當(dāng)前星期X(0-6,0代表星期天)
myDate.getTime(); //獲取當(dāng)前時間(從1970.1.1開始的毫秒數(shù))
myDate.getHours(); //獲取當(dāng)前小時數(shù)(0-23)
myDate.getMinutes(); //獲取當(dāng)前分鐘數(shù)(0-59)
myDate.getSeconds(); //獲取當(dāng)前秒數(shù)(0-59)
myDate.getMilliseconds(); //獲取當(dāng)前毫秒數(shù)(0-999)
myDate.toLocaleDateString(); //獲取當(dāng)前日期
var mytime=myDate.toLocaleTimeString(); //獲取當(dāng)前時間
myDate.toLocaleString( ); //獲取日期與時間
if (mytime<"23:30:00")
{
alert(mytime);
}
//-->
</SCRIPT>
<SCRIPT LANGUAGE="JavaScript">
<!--
var myDate = new Date();
myDate.getYear(); //獲取當(dāng)前年份(2位)
myDate.getFullYear(); //獲取完整的年份(4位,1970-????)
myDate.getMonth(); //獲取當(dāng)前月份(0-11,0代表1月)
myDate.getDate(); //獲取當(dāng)前日(1-31)
myDate.getDay(); //獲取當(dāng)前星期X(0-6,0代表星期天)
myDate.getTime(); //獲取當(dāng)前時間(從1970.1.1開始的毫秒數(shù))
myDate.getHours(); //獲取當(dāng)前小時數(shù)(0-23)
myDate.getMinutes(); //獲取當(dāng)前分鐘數(shù)(0-59)
myDate.getSeconds(); //獲取當(dāng)前秒數(shù)(0-59)
myDate.getMilliseconds(); //獲取當(dāng)前毫秒數(shù)(0-999)
myDate.toLocaleDateString(); //獲取當(dāng)前日期
var mytime=myDate.toLocaleTimeString(); //獲取當(dāng)前時間
myDate.toLocaleString( ); //獲取日期與時間
if (mytime<"23:30:00")
{
alert(mytime);
}
//-->
</SCRIPT>
2.如何用js得到 yyyy-mm-dd格式的當(dāng)前日期？
--------------------------------------------------------------------------------
view plaincopy to clipboardprint?
function appendZero(s){return ("00"+ s).substr((s+"").length);} //補(bǔ)0函數(shù)
var d = new Date();
alert(d.getFullYear() + "-" + appendZero(d.getMonth() + 1) + "-" + appendZero(d.getDate()));
function appendZero(s){return ("00"+ s).substr((s+"").length);} //補(bǔ)0函數(shù)
var d = new Date();
alert(d.getFullYear() + "-" + appendZero(d.getMonth() + 1) + "-" + appendZero(d.getDate()));
3.javascript 獲得指定日期的臨近日期的方法
view plaincopy to clipboardprint?
//取得日期字符串,返回YYYY-MM-DD
function getDate(date)
{
var thisYear = date.getYear();
var thisMonth = date.getMonth() + 1;
//如果月份長度是一位則前面補(bǔ)0
if(thisMonth<10) thisMonth = "0" + thisMonth;
var thisDay = date.getDate();
//如果天的長度是一位則前面補(bǔ)0
if(thisDay<10) thisDay = "0" + thisDay;
return thisYear + "-" + thisMonth + "-" + thisDay;
}
//取得日期時間字符串,返回YYYY-MM-DD HH:mm:SS
function getDateTime(date)
{
var thisYear = date.getYear();
var thisMonth = date.getMonth() + 1;
//如果月份長度是一位則前面補(bǔ)0
if(thisMonth<10) thisMonth = "0" + thisMonth;
var thisDay = date.getDate();
//如果天的長度是一位則前面補(bǔ)0
if(thisDay<10) thisDay = "0" + thisDay;
var thisHour = date.getHours();
//如果小時長度是一位則前面補(bǔ)0
if(thisHour<10) thisHour = "0" + thisHour;
var thisMinute = date.getMinutes();
//如果分鐘長度是一位則前面補(bǔ)0
if(thisMinute<10) thisMinute = "0" + thisMinute;
var thisSecond = date.getSeconds();
//如果分鐘長度是一位則前面補(bǔ)0
if(thisSecond<10) thisSecond = "0" + thisSecond;
return thisYear + "-" + thisMonth + "-" + thisDay + " " + thisHour + ":" + thisMinute + ":" + thisSecond;
}
//根據(jù)日期字符串生成日期對象,日期字符串格式為YYYY-MM-DD
function setDate(strDate)
{
var aDate = strDate.split("-");
return new Date(aDate[0],aDate[1]-1,aDate[2]);
}
//獲得指定日期的臨近日期
//strDate:指定的日期,格式為yyyy-mm-dd nDay:與指定日期相鄰的天數(shù) 1為明天 -1為昨天
function getNearDay(strDate,nDay)
{
try
{
var oDate = setDate(strDate);
var newDate = new Date(oDate.valueOf() + nDay*24*60*60*1000);
return getDate(newDate);
}
catch(ex)
{
return "error";
}
}
