js 日期格式转换---将日期类型转换成字符串型格式

本文介绍了一种使用JavaScript进行日期和时间格式化的实用方法。通过几个简单的函数，可以将JavaScript Date对象转换为符合特定格式的字符串，例如“yyyy-MM-dd”或“yyyy-MM-dd hh:mm”。这些函数有助于快速实现日期时间的格式化需求。

在编码过程中，遇到字符串转换问题，然后使劲找，终于……OK! 现在分享如下：

// 取得当前日期 , 格式 yyyy-mm-dd

function GetCurrentDate ()

{

var year = 0 ;

var Month = 0 ;

var day = 0 ;

var CurrentDate = new Date ();

return ChangeDateToString ( CurrentDate );

}

// 取得当前日期 , 格式 yyyy-mm-dd hh:mm

function GetCurrentTime ()

{

var Year = 0 ;

var Month = 0 ;

var Day = 0 ;

var CurrentDate = new Date ();

return ChangeTimeToString ( CurrentDate );

}

// 将日期类型转换成字符串型格式 yyyy-MM-dd

function ChangeDateToString ( DateIn )

{

var Year = 0 ;

var Month = 0 ;

var Day = 0 ;

var CurrentDate = "" ;

// 初始化时间

Year = DateIn . getYear ();

Month = DateIn . getMonth ()+ 1 ;

Day = DateIn . getDate ();

CurrentDate = Year + "-" ;

if ( Month >= 10 )

{

CurrentDate = CurrentDate + Month + "-" ;

}

else

{

CurrentDate = CurrentDate + "0" + Month + "-" ;

}

if ( Day >= 10 )

{

CurrentDate = CurrentDate + Day ;

}

else

{

CurrentDate = CurrentDate + "0" + Day ;

}

return CurrentDate ;

}

// 将日期类型转换成字符串型格式 yyyy

function ChangeDateYearToString ( DateIn )

{

var Year = 0 ;

var CurrentDate = "" ;

Year = DateIn . getYear ();

CurrentDate = Year ;

return CurrentDate ;

}

// 将日期类型转换成字符串型格式 MM

function ChangeDateMonthToString ( DateIn )

{

var Month = 0 ;

var CurrentDate = "" ;

Month = DateIn . getMonth ()+ 1 ;

if ( Month >= 10 )

{

CurrentDate = CurrentDate + Month ;

}

else

{

CurrentDate = CurrentDate + "0" + Month ;

}

return CurrentDate ;

}

// 将日期类型转换成字符串型格式 yyyy-MM-dd hh:mm

function ChangeTimeToString ( DateIn )

{

var Year = 0 ;

var Month = 0 ;

var Day = 0 ;

var Hour = 0 ;

var Minute = 0 ;

var CurrentDate = "" ;

// 初始化时间

Year = DateIn . getYear ();

Month = DateIn . getMonth ()+ 1 ;

Day = DateIn . getDate ();

Hour = DateIn . getHours ();

Minute = DateIn . getMinutes ();

CurrentDate = Year + "-" ;

if ( Month >= 10 )

{

CurrentDate = CurrentDate + Month + "-" ;

}

else

{

CurrentDate = CurrentDate + "0" + Month + "-" ;

}

if ( Day >= 10 )

{

CurrentDate = CurrentDate + Day ;

}

else

{

CurrentDate = CurrentDate + "0" + Day ;

}

if ( Hour >= 10 )

{

CurrentDate = CurrentDate + " " + Hour ;

}

else

{

CurrentDate = CurrentDate + " 0" + Hour ;

}

if ( Minute >= 10 )

{

CurrentDate = CurrentDate + ":" + Minute ;

}

else

{

CurrentDate = CurrentDate + ":0" + Minute ;

}

return CurrentDate ;

}
